Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio signals are stored temporarily in the audio storage means, then communication reliability is improved by enabling re-listening, but device complexity increases due to additional storage and control components
Solution Approach 1:
The patent combines the audio storage means with the existing audio signal processing path in the headset. The storage means is integrated into the signal flow so that received audio signals are automatically stored without requiring separate independent storage hardware, thereby reducing overall device complexity while maintaining reliability improvement.
Solution Approach 2:
The audio storage means serves multiple functions: it stores audio signals for replay, enables communication reliability improvement, and works integration with the existing output unit and operating unit. This multi-functionality reduces the need for separate dedicated components, addressing the complexity issue.
2Reliability
If the output unit increases the volume of reproduced audio signals, then comprehensibility is improved for repeated reproductions, but energy consumption increases
Solution Approach 1:
The output unit dynamically adjusts the volume of reproduced audio signals based on the reproduction count. The volume is increased specifically for repeated reproductions rather than maintaining a constant high volume, thereby improving comprehensibility when needed while minimizing energy consumption during initial or single reproductions.
Solution Approach 2:
The patent changes the volume parameter of the audio signal based on the reproduction history. By modifying this physical parameter dynamically according to whether it's a first or repeated reproduction, the system achieves better comprehensibility for replayed messages while avoiding continuous high energy consumption.
3Ease of operation
If the headset includes an operating unit for managing stored audio signals, then ease of operation is improved for replay control, but device complexity increases
Solution Approach 1:
The operating unit provides self-service functionality by enabling the user to directly control the replay of stored audio signals without requiring external devices or complex setup. The user can independently manage the stored messages through the integrated operating unit, improving ease of operation while keeping the system self-contained.
Solution Approach 2:
The operating unit extracts and provides control functionality specifically for managing stored audio signals, separating this control function from the main audio processing path. This modular extraction allows for simplified user interaction while maintaining overall system integration, balancing ease of operation with manageable complexity.
