Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional mounting mechanism with fixed seat, adjusting seat and buckle is used, then the gap between drawer and slide rail can be adjusted, but the structure becomes complex which increases manufacturing cost and makes assembly cumbersome

Engineering Contradiction:
Improvegap adjustment capabilityVSAvoidmounting mechanism structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the fixed seat, adjusting seat, and buckle into a single integrated mounting assembly. The mounting assembly includes a mounting body with a built-in adjusting mechanism that can directly adjust the gap between the drawer and slide rail without requiring separate components, thereby simplifying the structure while maintaining adjustment functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mounting assembly is designed to perform multiple functions within a single component structure. It provides both the mounting function and the gap adjustment function simultaneously, eliminating the need for separate fixed seat and adjusting seat components, thus reducing device complexity while preserving adaptability.

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

2Adaptability or versatility

If the traditional mounting mechanism adjusts the longitudinal gap between slide rail and drawer, then the gap can be modified, but the longitudinal positions of movable rail and fixed rail are reduced, decreasing cushioning distance and effect

Engineering Contradiction:
Improvegap adjustment capabilityVSAvoidcushioning effect
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements localized adjustment at the mounting assembly position rather than changing the overall longitudinal positions of the movable rail and fixed rail. The adjusting mechanism locally modifies the gap between the drawer and slide rail at the mounting point, preserving the cushioning distance and effect while achieving the desired gap adjustment.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The mounting assembly acts as an intermediary component between the drawer and the slide rail system. It provides the adjustment function through its built-in mechanism while isolating the adjustment action from the main rail positioning, thereby maintaining the cushioning effect of the slide rail system.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the longitudinal gap is adjusted to change the gap between mounting mechanism and drawer, then the gap can be modified, but the gap between tail hook and drawer increases or becomes too tight, causing large oscillating quantity and noise

Engineering Contradiction:
Improvegap adjustment capabilityVSAvoiddrawer stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The mounting assembly provides localized adjustment at its installation position, ensuring that the gap modification does not propagate to the tail hook connection. This localized approach allows independent optimization of the mounting gap without affecting the stability and oscillation characteristics of the tail hook to drawer connection.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent segments the adjustment function to be performed independently at the mounting assembly level, separate from the tail hook connection. This segmentation allows the gap adjustment to be isolated to a specific location, preventing unwanted changes in the tail hook gap and maintaining overall system stability.

Inventive Principle:
Principle #1Segmentation
