Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate remote controls are used for different components, then each component can be controlled independently, but the system becomes cluttered and complex

Engineering Contradiction:
Improvecomponent control independenceVSAvoidremote control quantity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by enabling a single remote control to perform multiple functions across different components. The universal remote receives infrared signals and can route them to different devices (TV, audio system, speakers) based on the signal type and system state, eliminating the need for separate remote controls for each component while maintaining independent control capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If additional speakers are added to the home theatre system, then audio quality is improved, but frequency response degradation occurs due to uncontrolled combination of sound output

Engineering Contradiction:
Improveaudio qualityVSAvoidfrequency response degradation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent implements feedback by having the audio system continuously monitor the operational state of both integrated and additional speakers. When additional speakers are detected as active, the system automatically adjusts the volume level of integrated speakers through feedback control, preventing frequency response degradation and ensuring optimal audio performance from the additional speaker system.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent applies dynamics by making the speaker volume control adaptive rather than static. The system dynamically adjusts the volume of integrated speakers based on real-time detection of additional speaker usage, transitioning between different volume states to maintain optimal frequency response while supporting both integrated and additional speaker systems.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If a universal remote control is programmed to control all functions, then clutter and confusion are reduced, but the programming task becomes tedious and time consuming

Engineering Contradiction:
Improveremote control quantityVSAvoidprogramming time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The patent applies self-service by enabling the remote control system to automatically identify and route infrared signals to the appropriate device without manual programming. The system detects the type of infrared signal received and autonomously determines which device should receive the signal based on current system state, eliminating the tedious manual programming process while maintaining universal control functionality.

Inventive Principle:
Principle #25Self-service
