Sliding Demountable Joint With Resilient Locking for Easy Release

Solution Overview

Problem

Conventional match structures, such as mortise and tenon joints, face challenges in achieving adequate structural strength during assembly while maintaining ease of disassembly, as increased strength often makes disassembly difficult.

Innovation Solution

A demountable assembly structure featuring a first and second body with sliding surfaces and an engaging component, including a slide switch and resilient element, allows for quick joining and separating by engaging and disengaging resilient arms within a channel, enhancing ease of use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the mortise and tenon joint is designed with increased structural strength to overcome inadequate assembly strength, then the assembly-related structural strength is improved, but the disassembly process becomes difficult

Engineering Contradiction:

Improveassembly structural strengthVSAvoiddisassembly ease

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The joint system is segmented into a mortise (recess), tenon (protrusion), and a separate fastening mechanism (screw or cam lever). This allows the alignment function (mortise and tenon) to be separated from the locking function (fastening mechanism), enabling strong assembly while maintaining easy disassembly through the independent fastening component.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A fastening mechanism (screw or cam lever) is introduced as an intermediary element between the mortise and tenon. This intermediary provides the necessary structural strength for assembly while allowing controlled disassembly, resolving the contradiction between strong bonding and easy separation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the mortise and tenon joint is designed for easy disengagement to improve disassembly convenience, then the disassembly process becomes easy, but the assembly-related structural strength becomes inadequate

3Device complexity

If conventional match structures are used for joining two objects in a separable manner, then the assembly process is simple, but the alignment precision between the two objects is insufficient

Engineering Contradiction:

Improveassembly process complexityVSAvoidalignment precision

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The mortise and tenon structures are designed with predetermined geometric shapes and dimensions that automatically guide the alignment of two objects during assembly. The tenon protrusion fits into the mortise recess, pre-establishing the correct positional relationship before final fastening, thus achieving precise alignment without complex adjustment procedures.

AI summary

A demountable assembly structure includes a first body, second body, and engaging component. The first body has a first sliding surface and a slide switch recess positioned proximate to the first sliding surface. The second body has a second sliding surface and an engaging channel positioned proximate to the second sliding surface. The engaging channel is opposite the slide switch recess. The engaging component has a slide switch and a resilient element. The resilient element has a basal portion fixedly disposed in the slide switch recess and a resilient engaging arm extended from the basal portion to the engaging channel and engaged inside the engaging channel. The resilient engaging arm has a guide surface opposite the engaging channel. When the first sliding surface slides onto the second sliding surface, the resilient engaging arm gets engaged inside the engaging channel by having the guide surface slid along the engaging channel.
