Exercises

Excercise 3:

Problem Statement: Soccer referees are bound make mistakes during the game, and these inaccuracies can affect the outcomes of games.

Fault Tree:

KT Problem Analysis:

Exercise 4:

Solution Search: General goal -> specific goals -> specifications

• public acceptance

  • avoid ruining spectator/fan experience

    • Functional: cannot delay game (needs to be fast)

    • Ergonomic: enhancing experience be allowing information to be accessible to fans

  • avoid hindering player experience

    • Physical: must be comfortable for player (small unnoticable devices)

  • make the game more enjoyable to watch

    • Ergonomic: enhancing experience be allowing information to be accessible to fans

• performance

  • record, send, and display information/data quickly

    • Functional: must have effective, high-performance middleware

    • Functional: middleware must be able to handle interference from fans cellular connection

  • clearly depict different degrees of contact severity

    • Functional: must have effective algorithms to interpret contact efficiently

• ease of operation

  • not requiring any maintance or supervision while in use

    • Physical: Device must be durable

    • Physical: Battery life must be substaintial or device can function on low power

• reliability

  • maintaining near 100% accuracy of real time events

    • Functional: Device must be thoroughly tested

  • endure the whole game with out malfunction

    • Physical: Device must be durable

Exercise 5:

Similiar Patent to Contaxt:

• Wireless motion sensor system and method

• Athletic Performance Monitoring Systems and Methods in a Team Sports Environment

Exercise 6: System Design Chart

Exercise 7:

Desired Function/Goals:

1. Stable network: Interference free connection, mesh network, stable servers

2. Comfortable/unnoticable: miniaturizing devices, soft electronics, convenient placement, minumal components/features

3. Durable: convenient placement, strong casing, good intergration, long battery

4. Minumum interfering with uniform brands: Portable/"accessorizable", in shin guards, under the uniform, in the cleat

Exercise 8 & 9: Ethics, Liability, and Failure and Hazard Anaylsis

Ethical issues:

1. Problem: Players finding a way to exploit the sensors to get calls their way

Solution: MVP must be the accuracy of the technology

2. Problem: Players using the embedded electronics to inflict more pain on their oppenents

Solution: the electronics must be miniturized to our best ability and corperated well into uniform.

Product liability:

1. Problem: Faulty readings after a longer use-time

Solution: either increased durability(product lifetime) or replaceability (lower cost)

2. Problem: Damaged device after extended use

Solution: increased durability/flexibility of electronics

3. Problem: Overuse of batteries

Solution: rechargeable devices

4. Problem: Need of frequent discarding of uniforms/product for better accuracy

Solution: make the device more of an over clothing/cleat accessory

Social impact

4. 1. Problem: Issues disposing of batteries

Solution: make devices rechargeable

4. 2. Problem: Fabric embedded electronic material not easily recyclable

Solution: make device easily removable and installable into uniform/cleat

Exercise 10: KT Decisions and Evaluation

Exercise 11: Implementation

11.1:Reconsidered System Design

• MVP: Woolven in electronic system with sensors that can connect to the internet

• Reason for change of desing focus: The technology needed to transmit and process the data is already available, however the technology required for embedding sensor technology in clothes comfortably would be the groundbreaking mvp.
