Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If screw coupling method is used to open and close the bracket, then the bracket can be fixed securely, but the screw coupling becomes loose after repeated use and the bracket cannot be fixed

Engineering Contradiction:

Improvebracket fixation reliabilityVSAvoidtime for bracket opening and closing

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent applies a dynamic coupling mechanism where the bracket can be quickly opened and closed through a simple locking action. The coupling structure transitions between locked and unlocked states dynamically, eliminating the need for repeated screw tightening while maintaining secure fixation during operation.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The bracket assembly is segmented into separable components with dedicated coupling parts. The electronic control device bracket is divided into a main body and a detachable cover portion, allowing independent opening and closing operations without affecting the entire structure.

Inventive Principle:

Principle #1Segmentation

2Reliability

If screw coupling is tight to prevent loosening, then the bracket remains secure, but it becomes difficult for the user to open and close the bracket

Engineering Contradiction:

Improvebracket fixation reliabilityVSAvoidease of bracket opening and closing

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The coupling mechanism provides dynamic adjustment capability, allowing the bracket to be securely locked during operation but easily opened when needed. The locking structure transitions between a tight secured state and an easily opened state through a simple user action.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

A coupling part acts as an intermediary between the bracket body and the cover portion. This intermediate structure provides both secure fixation when engaged and easy release when disengaged, mediating between the conflicting requirements of reliability and ease of operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If excessive force is applied to open and close the bracket with tight screw coupling, then the bracket can be opened, but the bracket may be damaged

Engineering Contradiction:

Improveease of bracket opening and closingVSAvoidbracket structural integrity

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The dynamic coupling mechanism allows the bracket to be opened and closed without applying excessive force. The locking and unlocking actions are designed to be performed with minimal force, preventing damage to the bracket structure while maintaining operational ease.

Inventive Principle:

Principle #15Dynamics

4Reliability

If screw coupling method is used, then the bracket can be fixed, but follow-up management of screws is difficult and lead time increases during production

Engineering Contradiction:

Improvebracket fixation reliabilityVSAvoidmanufacturing efficiency

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent extracts the screw coupling elements from the bracket assembly and replaces them with an integrated coupling structure. This eliminates the need for separate screw management during production and follow-up maintenance, simplifying both manufacturing and service operations.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The coupling function is merged into the bracket structure itself rather than being a separate assembly step. The coupling parts are integrated into the bracket and cover design, eliminating the need for separate screw fastening operations during manufacturing.

Inventive Principle:

Principle #5Merging (Combining)
