Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the hearing device at the deaf side constantly transmits audio signals to the contralateral hearing device, then the hearing capability for unilateral hearing users is improved, but the battery power consumption increases significantly

Engineering Contradiction:
Improvehearing capabilityVSAvoidbattery power consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies dynamics by making the transmission mode configurable between full-duplex and half-duplex modes. The system can dynamically switch between these modes based on user needs, allowing the hearing device to transmit audio signals when necessary while reducing transmission activity to conserve battery power when continuous transmission is not required, thus resolving the contradiction between hearing capability and power consumption

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameter of the wireless communication link by introducing configurable transmission modes. By allowing the system to switch between full-duplex and half-duplex modes, the patent modifies the transmission parameter to balance audio signal transmission needs with battery power conservation, directly addressing the technical contradiction

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the wireless communication link is always enabled for audio signal transmission, then the audio processing capability is improved, but the battery power consumption increases

Engineering Contradiction:
Improveaudio processing capabilityVSAvoidbattery power consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts the wireless communication link state by enabling or disabling it based on operational mode. In full-duplex mode, the link is enabled for comprehensive audio processing, while in half-duplex mode, it is selectively enabled only when needed, allowing the system to adapt between high audio processing capability and low power consumption states

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The hearing device autonomously manages the wireless communication link by automatically enabling or disabling it based on the selected operational mode. This self-service mechanism allows the system to optimize between audio processing capability and power consumption without requiring external intervention, resolving the contradiction through intelligent autonomous control

Inventive Principle:
Principle #25Self-service

3Reliability

If the hearing device operates in full-duplex mode for optimal audio transmission, then the audio quality is improved, but the battery consumption increases

Engineering Contradiction:
Improveaudio qualityVSAvoidbattery consumption
Core Design Contradiction:
ReliabilityVSUse of energy by stationary object

Solution Approach 1:

The patent applies dynamics by making the transmission mode configurable between full-duplex and half-duplex modes. The system can dynamically switch between these modes based on user needs, allowing the hearing device to transmit audio signals when necessary while reducing transmission activity to conserve battery power when continuous transmission is not required, thus resolving the contradiction between audio quality and power consumption
