Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wired connection is used for stereo reception in hearing communication devices, then reliable audio transmission is achieved, but convenience and aesthetics deteriorate due to wire breakage and visible wires
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. Hearing communication devices transmit audio signals wirelessly to a remote device, eliminating the need for physical cables and connectors. This substitution resolves the contradiction by maintaining reliable audio transmission through wireless protocols while completely eliminating the mechanical wire that caused convenience and aesthetic problems.
2Stability of the object's composition
If a wired connection is used for stereo reception, then stable signal transmission is achieved, but device aesthetics and user acceptance worsen due to visible wires
Solution Approach 1:
The patent substitutes the mechanical wire-based signal transmission system with an electromagnetic wireless communication system. The wired connection that provided stable signal transmission is replaced by wireless protocols that transmit audio data through the air, eliminating the visible wire that compromised device aesthetics and user acceptance.
Solution Approach 2:
The patent introduces a remote device as an intermediary that receives wireless audio signals and processes them into stereo output. This intermediary enables stable signal transmission without requiring physical connection between hearing aids, allowing the hearing aids to remain aesthetically pleasing while maintaining reliable audio delivery through the remote device.
3Ease of operation
If wireless communication is implemented for stereo reception, then convenience and aesthetics are improved, but system complexity increases due to multiple communication modes and protocols
Solution Approach 1:
The patent implements a universal communication system where the remote device can operate in multiple modes (stereo reception, monophonic reception, direct communication, eavesdropping, relaying) and support various wireless protocols. This multi-functionality allows a single device to handle diverse communication scenarios, improving user convenience while managing complexity through a unified platform that adapts to different requirements.
Solution Approach 2:
The patent creates a dynamic communication system where the hearing communication devices and remote device can adapt their communication mode based on environmental conditions and user needs. The system dynamically switches between different protocols and modes (direct connection, eavesdropping mode, relaying mode) to optimize performance, making the complexity manageable through adaptive behavior rather than fixed complex architecture.
