Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If external fixing components (screws or bolts) are used with screw structures and lock holes, then stable assembly is achieved, but operation complexity increases and assembly/disassembly time increases

Engineering Contradiction:

Improveassembly stabilityVSAvoidoperation complexity

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent replaces the traditional screw-bolt mechanical fastening system with a snap-fit mechanism combining resilient hooks and a connecting component. The resilient hooks automatically engage with the connecting component through elastic deformation, eliminating the need for threaded fasteners and external tools, thus simplifying operation while maintaining stable assembly

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The resilient hooks utilize their own elastic properties to automatically engage with and lock onto the connecting component without requiring external tools or additional fastening operations. The mechanism self-secures through the elastic recovery force of the hooks, enabling tool-free assembly and disassembly while ensuring stable connection

Inventive Principle:

Principle #25Self-service

2Reliability

If external tools (screw drivers or spanners) are used to lock fixing components, then reliable fixing is achieved, but assembly and disassembly speed decreases

Engineering Contradiction:

Improvefixing reliabilityVSAvoidassembly speed

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent replaces tool-dependent mechanical fastening with a tool-free snap-fit system. The resilient hooks engage with the connecting component through elastic deformation and automatic locking, achieving reliable fixing without requiring screw drivers or spanners, thereby enabling rapid assembly and disassembly operations

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The resilient hooks are pre-designed with elastic properties that enable them to automatically engage and lock onto the connecting component during the assembly process itself, without requiring subsequent tool-based tightening operations. This preliminary self-locking action ensures reliable fixing while maintaining high assembly speed

Inventive Principle:

Principle #10Preliminary action

3Stability of the object's composition

If multiple combining portions are used to enhance connection stability, then assembly stability improves, but the risk of resilient deformation increases

Engineering Contradiction:

Improveconnection stabilityVSAvoiddeformation risk

Core Design Contradiction:

Stability of the object's compositionVSReliability

Solution Approach 1:

The patent introduces the connecting component as an intermediary element that mediates between multiple resilient hooks. This connecting component provides a stable engagement interface that distributes and controls the elastic deformation forces, allowing multiple hooks to work together to enhance connection stability while preventing uncontrolled resilient deformation through the mediating structure

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A fixing mechanism is used to fix a first electronic component to a second electronic component of an electronic apparatus. The fixing mechanism includes a detachable frame, a constraining component, a combining component and an actuating component. The first electronic component is assembled with the detachable frame via a first plate portion of the detachable frame. The constraining component is movably disposed on the detachable frame. The constraining component abuts against the first plate portion. The combining component is disposed on the detachable frame and corresponds to a connecting component of the second electronic component. The actuating component is movably disposed on the detachable frame. The combining component and the connecting component are matched in a loose manner via the actuating component in a first position, and matched in a tight manner via the actuating component in a second position.
