Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connection is used to connect earpieces to processing device, then reliability of connection is improved, but wearing comfort deteriorates and accidental removal risk increases
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. The earpieces communicate with the processing device via wireless signals, eliminating physical cables that cause discomfort and accidental removal while maintaining reliable connection through robust wireless communication protocols.
2Stability of the object's composition
If wired connection is used to connect earpieces to processing device, then connection stability is improved, but risk of accidental removal increases
Solution Approach 1:
The patent eliminates the mechanical connection system that causes accidental removal by implementing wireless communication. The earpieces maintain stable connection through wireless signals without physical attachments that can be caught on branches or other objects during combat operations.
3Ease of operation
If wireless communication is implemented, then wearing comfort is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic action by enabling wireless communication only when needed for communication tasks rather than continuous operation. The processing device activates wireless transmission functions during communication phases and reduces power consumption during audio processing phases, balancing communication needs with power management.
