Solution Overview

Problem

Existing connection members often deform during disassembly, leading to reduced service life and compromised assembly quality, and lack features to prevent unauthorized disassembly.

Innovation Solution

A connection member design featuring a body with a recess and slots for an apparatus, retaining surfaces with ribs, pre-contact members, an intermediate member that folds for assembly/disassembly, and a flexible member that acts as a spring to prevent unintentional movement, allowing secure mounting and demounting only with an apparatus.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a connection member is designed to be easily disassembled, then ease of operation is improved, but the connection member undergoes severe deformation during disassembly and becomes unusable

Engineering Contradiction:
Improveease of disassemblyVSAvoidstructural integrity
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The connection member is divided into distinct functional segments: a body portion, an intermediate member with pre-contact members, and a flexible member. This segmentation allows the disassembly force to be distributed across multiple components rather than concentrating stress on a single structure, enabling easy disassembly while preserving overall structural integrity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The intermediate member is designed to be foldable during assembly and disassembly operations. This dynamic characteristic allows the connection member to adapt its structure during operation - the intermediate member can fold to accommodate the apparatus and facilitate easy disassembly, then return to its original position to maintain structural integrity and prevent deformation.

Inventive Principle:
Principle #15Dynamics

2Reliability

If a connection member is designed for secure fixation, then reliability is improved, but unauthorized disassembly cannot be prevented

Engineering Contradiction:
Improvesecure fixationVSAvoidunauthorized disassembly prevention
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The flexible member acts as an intermediary element between the body and the intermediate member. It provides a controlled interface that allows the connection to be securely fixed while requiring specific apparatus interaction for disassembly. The flexible member's spring characteristics ensure that normal operational forces cannot disassemble the connection, yet the designated apparatus can overcome this resistance when properly applied.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If a connection member uses simple clipping design, then ease of manufacture is improved, but the connection member moves unintentionally and lacks retention

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidposition stability
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The pre-contact members are positioned to contact the workpiece before the main connection is established. This local action at a specific location provides immediate stabilization and prevents unintentional movement during the assembly process, while the overall manufacturing process remains simple and straightforward.

Inventive Principle:
Principle #3Local quality
