Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If board-fixing members are adjusted to level the electrical installation box by cutting and using adhesive, then the installation box can be leveled, but it becomes difficult to assemble and disassemble, and the gluing area decreases after cutting

Engineering Contradiction:
Improveleveling precisionVSAvoidassembly and disassembly ease
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The leveling mechanism is segmented into a separate adjustable component (leveling member with threaded rod) that can be independently adjusted without cutting the board-fixing member. This allows the board-fixing member to remain intact for easy assembly and disassembly while achieving precise leveling through the threaded adjustment mechanism

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A leveling member with a threaded rod acts as an intermediary between the board-fixing member and the electrical installation box. This intermediary component provides the adjustment function, allowing the board-fixing member itself to remain uncut and maintain its full gluing area while still achieving precise leveling

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If board-fixing members are cut to adjust length, then the installation box can be positioned correctly, but the gluing area decreases and assembly becomes more difficult

Engineering Contradiction:
Improvepositioning adaptabilityVSAvoidassembly ease
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The board-fixing system incorporates an adjustable leveling member with a threaded rod that can be dynamically adjusted to different lengths and positions without cutting. This dynamic adjustment mechanism provides positioning adaptability while keeping the board-fixing member intact for easy assembly

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Instead of changing the physical dimensions of the board-fixing member through cutting, the system changes the position parameter by adjusting the threaded rod of the leveling member. This allows positioning adaptability while maintaining the original gluing area and assembly simplicity

Inventive Principle:
Principle #35Parameter changes

3Reliability

If adhesive is used to mount the board-fixing member, then the installation box can be secured, but it becomes difficult to disassemble and the gluing area is reduced after cutting

Engineering Contradiction:
Improvemounting reliabilityVSAvoiddisassembly ease
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The mounting system is segmented into the board-fixing member and a separate adjustable leveling member. The board-fixing member itself is not cut, maintaining full gluing area for reliable mounting, while the adjustable component handles positioning and allows for easier disassembly through the threaded adjustment mechanism

Inventive Principle:
Principle #1Segmentation
