Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single light-transmitting element is used to achieve adjustable light transmittance, then light control function is improved, but heat and sound insulation performance deteriorates

Engineering Contradiction:

Improvelight transmittance adjustmentVSAvoidheat and sound insulation

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The single light-transmitting element is divided into multiple independent light-transmitting elements (first light-transmitting element, second light-transmitting element, etc.). Each element can be independently controlled to achieve light transmittance adjustment, while the multiple elements collectively provide improved heat and sound insulation through the air gaps between them.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple light-transmitting elements are arranged in a nested configuration with switchable light control elements positioned between them. This nested structure allows each layer to contribute to both light control and thermal/acoustic insulation, with the air gaps between nested elements enhancing the insulation performance.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Object-affected harmful factors

If multiple light-transmitting elements are added to improve heat and sound insulation, then insulation performance is improved, but device complexity increases

Engineering Contradiction:

Improveheat and sound insulationVSAvoidstructure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

Multiple light-transmitting elements and switchable light control elements are merged into a single integrated assembly. The elements are positioned in relation to each other within a common structure, allowing the entire multi-element system to function as one unified device for light control and insulation, rather than separate components.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

Each light-transmitting element and switchable light control element is designed to perform multiple functions simultaneously: light transmission, heat insulation, and sound insulation. This multi-functionality reduces the need for separate dedicated insulation layers, thereby limiting the increase in device complexity while achieving improved insulation performance.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If switchable light control elements are positioned between light-transmitting elements, then light control efficiency is improved, but manufacturing difficulty increases

Engineering Contradiction:

Improvelight control efficiencyVSAvoidassembly difficulty

Core Design Contradiction:

ProductivityVSEase of manufacture

Solution Approach 1:

The switchable light control elements are pre-positioned between the light-transmitting elements during the assembly process. This preliminary positioning ensures optimal alignment and spacing for maximum light control efficiency, while also simplifying the final assembly by having components already in their correct positions before final integration.

Inventive Principle:

Principle #10Preliminary action
