Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If light blocking parts are provided for each light source to prevent light leakage, then light leakage prevention is improved, but device complexity and cost increase

Engineering Contradiction:

Improvelight leakage preventionVSAvoidconfiguration complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the light blocking function into a single common structure (the board) that serves all light sources simultaneously, rather than providing separate light blocking parts for each light source. The board is positioned to block light from all light sources in one unified approach, reducing the number of components while maintaining effective light isolation.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The board serves multiple functions: it acts as a mounting substrate for the light sources, provides light blocking to prevent leakage, and structurally supports the entire assembly. This multi-functional design eliminates the need for separate dedicated light blocking parts for each light source.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If light blocking parts are provided for each light source to prevent light leakage, then false recognition prevention is improved, but manufacturing cost increases

Engineering Contradiction:

Improvefalse recognition preventionVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent combines the light blocking function into a single common board structure that serves all light sources, reducing the total number of components that need to be manufactured and assembled. This merging approach lowers manufacturing costs while maintaining effective prevention of light leakage and false recognition.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The board performs multiple functions including mounting light sources and blocking light, eliminating the need for separate dedicated light blocking parts. This reduces component count and assembly steps, thereby reducing manufacturing cost while maintaining reliability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If multiple light sources are disposed in parallel, then charging state display capability is improved, but light mixture and leakage occur

Engineering Contradiction:

Improvecharging state display capabilityVSAvoidlight mixture

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The board acts as an intermediary structure between multiple light sources, providing physical separation and light blocking. It serves as a mediator that allows multiple light sources to operate in parallel for enhanced display capability while simultaneously preventing their light from mixing through its light-blocking properties.

Inventive Principle:

Principle #24Intermediary (Mediator)
