Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a cable connection is used to connect the helmet-mounted communications assembly to the microphone-including unit, then the system can transmit voice-carrying signals between the components, but the rider must perform cumbersome plugging and unplugging procedures when donning or doffing the helmet

Engineering Contradiction:

Improvesignal transmission reliabilityVSAvoidconvenience of helmet donning/doffing

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical cable connection system with a wireless communication system. The helmet-mounted communications assembly uses a wireless microphone and speaker that transmit signals to and from the microphone-including unit without physical cable connections, eliminating the need for plugging and unplugging operations while maintaining reliable voice-carrying signal transmission

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a wireless signal transmission mechanism as an intermediary between the helmet-mounted communications assembly and the microphone-including unit. This wireless intermediary enables signal exchange without direct physical connection, allowing the rider to freely don and doff the helmet without affecting communication functionality

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a cable connection is required between the helmet-mounted assembly and microphone-including unit, then voice-carrying signals can be transmitted, but the structure becomes more complex and the operation more cumbersome

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent eliminates the mechanical cable connection structure entirely by implementing a wireless communication system. The helmet-mounted assembly uses wireless transmission components that replace the cable-jack connection mechanism, simplifying the overall device structure while maintaining reliable voice signal transmission capability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts and removes the cable connection component from the system. By taking out the physical cable and jack receptacle elements, the design achieves a simpler structure that maintains functionality through wireless signal transmission between the helmet-mounted assembly and microphone-including unit

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A communication system for a user having a helmet including earphones and a microphone and including a two-way radio and a microphone-including unit carried by the user and connected to the two-way radio includes a sensor for sensing the presence of the user's head within the helmet. A transmitter associated with the sensor transmits a wireless signal to the microphone-including unit which enables the microphone-including unit to wirelessly receive voice-carrying signals transmitted from the helmet microphone for conductance to the two-way radio and enables the microphone-including unit to wirelessly transmit voice-carrying signals which are received by the microphone-including unit from the two-way radio to the helmet earphones. In addition, helmet-carried componentry permits the user to simultaneously communicate through the two-way radio and a bluetooth enabled cell phone.
