Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the earphone monomers are made rotatable to improve wearing comfort, then the adaptability is improved, but the device lacks damping force effect resulting in unsatisfactory hand feeling

Engineering Contradiction:

Improvewearing comfortVSAvoidlack of damping force

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The patent applies beforehand cushioning by incorporating elastic elements (springs) within the pivoting structure of the sliding rod before the rotation movement occurs. These elastic elements are pre-positioned to provide damping force during the rotation of earphone monomers, cushioning the movement and providing satisfactory hand feeling while maintaining the adaptability of rotatable design

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Device complexity

If conventional assembly methods are used, then the device complexity is low, but the ease of manufacture deteriorates due to difficult assembly process

Engineering Contradiction:

Improvestructure simplicityVSAvoidease of assembly

Core Design Contradiction:

Device complexityVSEase of manufacture

Solution Approach 1:

The patent applies segmentation by dividing the headset into modular components: headband, sliding rods with pivoting structures, suspension brackets, and earphone monomers. Each component is designed as an independent module that can be assembled separately through the limitation blocks and limitation slots mechanism, significantly improving ease of manufacture while maintaining relatively simple device complexity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies self-service through the self-limiting assembly mechanism where limitation blocks on sliding rods automatically engage with limitation slots on suspension brackets during assembly. This self-guided assembly process eliminates the need for complex alignment procedures or specialized assembly tools, making the device easy to manufacture while keeping the structure relatively simple

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If the earphone monomers are made rotatable to fit ears better, then the adaptability is improved, but the hand feeling effect deteriorates without damping force

Engineering Contradiction:

Improvefitting capabilityVSAvoidhand feeling

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements beforehand cushioning by pre-installing elastic elements within the pivoting structure of the sliding rod. These elements are positioned in advance to provide damping force during the rotation operation of earphone monomers, ensuring satisfactory hand feeling while maintaining the fitting capability through rotatable design

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)
