Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If display modules are fixed rigidly to minimize movement, then structural stability is improved, but risk of cracks during assembly and operation increases

Engineering Contradiction:

Improvestructural stabilityVSAvoidrisk of cracks

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent applies the dynamics principle by replacing rigid fixed connections with movable guide mechanisms. Display modules are guided along tracks that allow controlled movement in assembly direction while maintaining positional stability during operation. This dynamic approach enables the structure to adapt to assembly variations without generating harmful stresses that cause cracks.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements beforehand cushioning by incorporating guide mechanisms with built-in compliance and tolerance compensation. The guide structure includes features that absorb assembly misalignments and operational variations before they can transmit harmful forces to the display panels, thereby preventing cracks while maintaining stability.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Reliability

If display modules are connected with complex locking mechanisms to ensure stability, then reliability is improved, but ease of installation and maintenance deteriorates

Engineering Contradiction:

Improveconnection reliabilityVSAvoidease of installation

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces complex mechanical locking systems with a simplified guide-based positioning mechanism. Display modules are secured through geometric constraints and friction-fit guides rather than multiple screws and locks. This substitution maintains connection reliability through precise guiding while dramatically improving ease of installation and maintenance.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts and removes unnecessary complex locking components from the connection system. By relying on the guide structure itself to provide both positioning and securing functions, the design eliminates separate locking mechanisms, thereby simplifying assembly and maintenance procedures while maintaining sufficient connection reliability.

Inventive Principle:

Principle #2Taking out (Extraction)

3Reliability

If display modules are connected with complex locking mechanisms to ensure stability, then reliability is improved, but device complexity increases

Engineering Contradiction:

Improveconnection reliabilityVSAvoidconnection structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing the guide structure to perform multiple functions simultaneously: positioning, guiding, securing, and allowing controlled movement. This multi-functional guide mechanism replaces multiple separate components (positioning fixtures, locking mechanisms, adjustment devices), thereby reducing overall device complexity while maintaining connection reliability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges separate connection functions into a unified guide structure. The guiding mechanism integrates positioning, constraint, and securing functions that would traditionally require multiple independent components. This merging simplifies the connection structure while ensuring reliable attachment of display modules.

Inventive Principle:

Principle #5Merging (Combining)
