Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wires are used to connect circuit boards linearly for electrical connection, then electrical connection is achieved, but assembly becomes cumbersome and assembly efficiency decreases

Engineering Contradiction:
Improveassembly easeVSAvoidassembly efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent extracts and eliminates the wire component from the electrical connection system. Instead of using wires to connect circuit boards, the invention integrates electrical contacts directly into the circuit board structure, allowing direct electrical connection without intermediate wiring components.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the electrical connection function with the mechanical support structure. The circuit board is designed with integrated contacts that combine structural support and electrical conduction functions into a single unified component, eliminating the need for separate wire connections.

Inventive Principle:
Principle #5Merging (Combining)

2Device complexity

If wires are used to connect multiple light-emitting bodies, then electrical connection is achieved, but the structure becomes complex and uniform luminescence cannot be realized

Engineering Contradiction:
Improvestructural complexityVSAvoiduniform luminescence
Core Design Contradiction:
Device complexityVSIllumination intensity

Solution Approach 1:

The patent segments the light-emitting bodies into modular units, each with integrated electrical contacts. This segmentation allows for standardized connection interfaces that simplify the overall structure and enable uniform electrical connection across all modules, resulting in uniform luminescence.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The circuit board is designed with universal connection features that serve multiple functions: mechanical support, electrical connection, and positioning. This multi-functionality reduces structural complexity while ensuring uniform electrical distribution to all light-emitting elements.

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

3Ease of manufacture

If wires are welded to circuit boards for fixing, then electrical connection is achieved, but the appearance becomes messy and aesthetic appeal decreases

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidappearance
Core Design Contradiction:
Ease of manufactureVSShape

Solution Approach 1:

The patent removes the wire component entirely from the design, extracting the aesthetic problem caused by visible wiring. The electrical connection is achieved through integrated contacts that are concealed within the circuit board structure, resulting in a clean, wire-free appearance.

Inventive Principle:
Principle #2Taking out (Extraction)

4Productivity

If conventional wire-based connection is used, then electrical connection is achieved, but time-consuming assembly process reduces productivity

Engineering Contradiction:
Improveassembly efficiencyVSAvoidassembly time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent incorporates electrical contacts directly into the circuit board during manufacturing, performing the electrical connection preparation in advance. This preliminary action eliminates the need for time-consuming wire welding and connection steps during assembly, significantly reducing assembly time and improving productivity.

Inventive Principle:
Principle #10Preliminary action
