Element D: DESIGN CONCEPT GENERATION, ANALYSIS, AND SELECTION

Due 2/14

Reflective Questions:

What brainstorming or idea generations techniques did I/we use to help define possible solutions and how can we show that I/we kept all of the design requirements in mind throughout the entire process?
What was the best solution to try and why was it the best solution to try?

Include:

Multiple design solutions.
Detailed concept sketches, schematics, annotated drawings
A discussion of the brainstorming process and how it you narrowed it down to your final selection
Detailed and prioritized list of all design goals and requirements.

- Features desired in final design
- Specifications
- Constraints
- Parameters

Reflection and analysis of design goals and requirements identified and prioritization.
A decision matrix.
A final design with justification for selection.
Your team’s Gantt chart to detail all tasks, responsible parties, and due dates. Clearly define the entire scope of work in the task list. Be sure to consider the Rule of Thirds when making scheduling projections.

Annotated Drawings

Sketch 1: Spray Concept

Sketch 2: Sleeve Concept

In this concept sketch, I visualize a cable sprayed with a capacacin-integrated flexible coating. By spraying individual cable rolls, the capsaicin can be easily integrated into the design of individual parts, and adjusted by adding bite-resistant mesh and thick, durable insulating sleeves.

Flexible, long lasting, and durable, the capsaicin-incorporated sleeve surrounds the outermost layer of a power line, providing additional safety from a taste-based standpoint. With easier accessibility and no environmental concerns, consumers implement the sleeve individually, and are more likely to buy the product.

Sketch 3: Heat Shrink

Sketch 4: RTV Rubber

This heat shrink infused with capsaicin can be easily coated onto wires by use of a household hair dryer or a heat gun. A squirrel that bites into the heat shrink will be repelled by the taste of the unsavory capsaicin.

In this design, the Capsaicin could be dissolved into an oil, and dispersed into micro-droplets throughout. RTV Rubber, a room-temperature drying casting material, also works well as an insulator, and could be easily applied by a consumer. Some possible issues with the design include fumes while applying and cleanup.

Sketch 5: Paint concept

The paint design uses a very basic feature. By blending in the capsaicin into the paint mixture, buyers are able to apply it to virtually any surface creating a layer of protection. The paint method requires more time to dry but will create a more permanent solution.
