Engineering design process

1.    Identify Customer need or opportunity

Street light wont turn off during daylight hours

2.    Problem Definition♦

The sensors in the light are not detecting the ambient light to turn of the light during the daylight. The type of technology used in the street light. The design might make  it difficult to put certain sensors on them. Height may be an issue. Surrounding objects such as trees, building, and wildlife. Street light and repair might disrupt traffic.

3.    Data and Information Collection

Checking for correct Photocell and/or Replacing bad photocell that detects sunlight.

4.    Development of Alternative Designs

Completely redesign to our own specifications, add  360 degree detection sensor, repair malfunctioning parts. AND WE CAN CHANGE THE LIGHT BULB.

5.   Selection of optimal Design

Bright enough to light up street but not enough to blind drivers at night, and something to block street light’s light from shining into neighborhood houses. Critter deterent to prevent birds/animals from making house in the light.Add in a 36o° photocell to turn off light during slight daytime for when it storms. built in lighting rod to prevent lighting from damaging the street light.

1.    Identify Customer need or opportunity

Computer mouse causing Carpal Tunnel after excessive use

2.    Problem Definition

Many people working at a desk or in an office use a computer mouse a lot of the time. Even at home, people are using computers and computer mice, causing strain and injury in their hand an arm. Clicking, twisting of arm, curvature of hand, and gripping of mouse causes these problems. The more injured they are, the more time they need to take off of work and the more that costs the company money.

3.    Data and Information Collection

Common solutions

Different mice, such as:

  • Ergonomic mouse
  • Track pad (laptops)
  • Vertical Mouse
  • Trackball

4.    Development of Alternative Designs

 One good alternative would be a glove mouse, which is a mouse integrated into a glove that you wear on your hand.

5.   Selection of optimal Design

Best design would probably be the glove mouse. There would be no grip, no curvature of hand, you and could be used virtually anywhere so you wouldn’t have to twist your arm.

1.    Identify Customer need or opportunity

Garbage disposal will not break down enough to go down drain.

2.    Problem Definition

     The garbage disposal will only grind certain types of food when put into the grinding chamber.  It will grind tomatoes, potatoes etc., softer foods and it doesn’t matter the size or amount.  The disposal is having problems grinding rice, artichoke, celery, etc., foods that are more grainy and an all together tougher food.  The drain is constantly becoming clogged and much time is spent disposing of the non grinding food when it should easily go down the drain.

     The motor needs to be larger and maybe sharper blades inside the disposer itself.  The cost of a new disposer with the horsepower to grind the food expected to be ground will be significantly higher.  Custom blades will have to be bent or rolled then reinstalled to achieve adequate chopping of the tougher foods.  These two obstacles will put the disposals price twice what most are wanting to pay.  An upgraded electrical outlet may also be required or heavier gauge wire my need installed to power the newly added horsepower.  Also the safety of a disposal with higher horsepower and sharper blades will be a concern.  If a person was to drop silverware or something other they would have to reach into the extra sharp blades and retrieve it.  Maybe causing a laceration then turn infection from the contents of saturated old food residue.  Another issue would be the size of the opening the upgraded unit will need to be installed in, as well as the durability of the sink itself.  A larger unit may be more apt to cause leaking around the basket seal, where it attaches to the lip of the sink.  Even causing some thinner stainless steel sinks to partially collapse.

     It would be in the best interest of the consumer as well as economically feasible to dispose of the harder, grainier foods into the waste basket.  We don’t believe many consumers will pay the extra cost attributed with the upgraded disposal.  The market will be to small for the upgraded unit making it unprofitable.

3.    Data and Information Collection

     We will need to reconfigure the blade design for chopping  maybe even add an additional blade inside the grinding chamber. The blades may have to be taken back to square one for reshaping, in order to have an optimum chopping ability. Reconfiguring a new smaller motor with more horsepower would be optimal but the cost of taking it all the way back to design could would also become more costly. 

     There are many disposers on the market now with a huge price difference.  The solution and the best and most cost effective is buying a different garbage disposer, though the same problem my exist with the next one causing the consumer to return it.  

4.    Development of Alternative Designs

     The consumer or whoever could be given suggestions to begin composting more of there food waste instead of sending them down the garbage disposal.  The purchaser of the disposer could be given a list of the basic designs of compost bins and other ways to utilize food wastes.   

     Another design with a smaller mouth could solve some of the non-grinding issues.  Also with a smaller disposal mouth the customer would have to cut the food waste into smaller pieces before placing them into the grinding chamber.  The blades them would be closer having more of an instant grinding technique compared to previous disposers.

5.   Selection of optimal Design

     Garbage disposals are a widely used home appliance that many household have problems with.  Disposers that don’t properly grind food waste begin a slow problem of buildup inside waste lines, gathering food waste  until the line clogs.  Also people are constantly digging food from garbage disposals which should not have been inserted into the disposer in the first place.  Most consumers will continue the same methods of disposal putting the wrong foods into the grinding chamber knowing the resulting problem.  Maybe out of laziness or just giving it another try people will keep putting the same unwanted food down the drain. 

      A new design could be ideal but we would need to take it to the design table for affordability, today the market is saturated enough.

Engineering design process

1.    Identify Customer need or opportunity

Customer needs to store large amounts of data with backup.

2.    Problem Definition

The problem is pretty simple, our customer wants to store large amounts of data on his personal computer with a backup of all the data as security. The problem is he/she is not very knowledgeable with modern technology, so there will cost and time to set up for he/she.  Also tech materials may be expensive or troublesome to implement. 

3.    Data and Information Collection

1.Extra Internal hard drive that data is stored on then disconnected

2. External Hard Drive for easy use.

3. Flash drives for simple small items.

4.    Development of Alternative Designs

One good alternative idea is to have a cloud storage system that is accessible on the internet where ever the customer goes.

5.   Selection of optimal Design

We chose the external hard drive in combination the the cloud storage system so the customer can have double the security along with the simple use of each product.
