Solution Overview

Problem

Conventional fastener structures for handles and coupling counterparts are inflexible, leading to protrusion interference, collision risks, and difficulty in disassembly due to fixed screw connections, which complicates portability and repeated coupling/separation.

Innovation Solution

A fastener structure featuring a body with a fastening portion that includes a neck for assembly with a coupling counterpart, allowing for easy connection and disconnection by using a fixing connection portion and abutting elements to maintain the neck in a withdrawn position, enabling the handle to be removed when not in use and facilitating quick coupling and separation of objects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If screws are used to lock and fix the handle on the object, then the handle can be firmly connected to the object, but the handle cannot be collapsed or removed, causing protrusion interference and collision risks

Engineering Contradiction:
Improveconnection strengthVSAvoidhandle collapsibility
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The patent applies the dynamics principle by designing a handle with a movable connection mechanism that transitions between extended and collapsed states. The handle body can rotate relative to the object surface, allowing it to be extended for use and collapsed for storage, transforming a static fixed connection into a dynamic adjustable connection that adapts to different usage conditions.

Inventive Principle:
Principle #15Dynamics

2Strength

If screws are used to fix the handle on the object, then the handle can be firmly connected, but the assembly process becomes complicated and disassembly is difficult

Engineering Contradiction:
Improveconnection strengthVSAvoidassembly process complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the connection system into distinct modular components: a handle body, an object with a receiving structure, and a fastening mechanism. This modular design allows each component to be independently manufactured and assembled, simplifying the overall assembly process while maintaining strong connections through the segmented fastening system.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the handle constantly protrudes from the object surface, then it is always accessible for use, but it causes interference in object arrangement and collision risks when not in use

Engineering Contradiction:
Improvehandle accessibilityVSAvoidprotrusion interference
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent resolves this contradiction by making the handle dynamically adjustable between extended and collapsed positions. When not in use, the handle can be collapsed flush with the object surface, eliminating protrusion interference and collision risks. When needed, it can be extended for easy accessibility, thus adapting to different operational states.

Inventive Principle:
Principle #15Dynamics

4Strength

If screws are used for coupling objects, then the objects can be firmly coupled, but the coupling cannot be easily separated for repeated use

Engineering Contradiction:
Improvecoupling strengthVSAvoiddisassembly ease
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The patent applies dynamics to the coupling mechanism by designing a reversible fastening system that transitions between locked and unlocked states. The coupling can be firmly secured when needed but can also be easily released and resecured for repeated coupling and separation operations, transforming static permanent fastening into dynamic reversible fastening.

Inventive Principle:
Principle #15Dynamics

AI summary

A fastener structure includes a body and a fastening portion. The fastening portion is provided on one end of the body, and includes a neck configured to be receivingly fastened into, assembled into or fitted with a coupling counterpart. Thus, the handle and the coupling counterpart may be assembled during use, and the handle may be removed from the coupling counterpart when not in use, achieving effects of easy operation and collision prevention. Further, the fastener structure may be assembled to a first object, and be fastening connected to a second object or removed from the second object so as to complete coupling or separation of at least two objects, achieving the effect of repeated quick coupling and separation.
