Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional buckling components, sliding components and latches are used to connect casings, then connecting strength is improved, but structural space requirement increases and device complexity increases

Engineering Contradiction:

Improveconnecting strengthVSAvoidstructural space

Core Design Contradiction:

StrengthVSVolume of stationary object

Solution Approach 1:

The patent combines multiple functions into a single integrated buckling component. The buckling component simultaneously provides connecting strength, acts as a latch, and eliminates the need for separate sliding components and latches. This merging of functions reduces the overall structural space while maintaining the required connecting strength between casings.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The buckling component is designed as a multi-functional element that performs multiple roles: it provides mechanical connection strength, acts as a locking mechanism, and enables rapid assembly/disassembly without requiring separate dedicated components for each function. This universality reduces the total number of parts and the space they occupy.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Strength

If conventional buckling components, sliding components and latches are used to connect casings, then connecting strength is improved, but device complexity increases

Engineering Contradiction:

Improveconnecting strengthVSAvoidstructural complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The patent merges the functions of buckling components, sliding components, and latches into a single integrated mechanism. This reduces the number of separate parts and simplifies the overall structure while maintaining the necessary connecting strength and locking functionality.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated buckling component serves multiple purposes simultaneously: providing connection strength, enabling locking, and facilitating rapid assembly/disassembly. This multi-functionality reduces device complexity by eliminating the need for multiple specialized components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Strength

If conventional casings with multiple components are used, then connecting strength is improved, but assembly and disassembly time increases

Engineering Contradiction:

Improveconnecting strengthVSAvoidassembly time

Core Design Contradiction:

StrengthVSLoss of time

Solution Approach 1:

The patent extracts and eliminates unnecessary intermediate components (separate sliding components and latches) from the assembly process. By removing these redundant elements, the assembly and disassembly operations are simplified and accelerated, while the integrated buckling component maintains the required connecting strength.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The buckling component is designed to automatically engage and lock into position through its own structural features, eliminating the need for separate locking operations or additional components. This self-service mechanism reduces assembly time while maintaining secure connection.

Inventive Principle:

Principle #25Self-service

AI summary

A detachable combining device for covering an electronic module is disclosed in the present invention. The detachable combining device includes a first casing having an engaging portion, a second casing, a buckling component pivotably disposed on the second casing, and a latch slidably disposed on the second casing. The buckling component buckles the engaging portion of the first casing, so as to constrain movement between the first casing and the second casing. The latch is for sliding relative to the second casing along a first direction to move the buckling component, so that the buckling component pivots relative to the second casing for disassembling from the engaging portion.
