Solution Overview

Problem

Existing electronic devices require complex and damaging disassembly processes, leading to potential damage of internal parts and wear of screw threads due to repeated coupling and disassembly.

Innovation Solution

A disassembling apparatus with a base part, movable part, fixing part, and separation part that facilitates easy disassembly of electronic devices by spacing the housings apart and using snap-fitting mechanisms to separate the upper and lower housings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional coupling tools (screws) are used to couple the housing, then the housing can be securely assembled, but the disassembly process becomes complex and time-consuming requiring removal of multiple coupling tools

Engineering Contradiction:

Improveease of assemblyVSAvoiddisassembly time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The coupling mechanism is segmented into a coupling protrusion on the upper housing and a coupling recess on the lower housing, allowing the housing to be divided into separable sections that can be quickly detached without requiring removal of multiple fastening elements

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of using traditional screw-fastening where the fastener must be removed to separate parts, this invention uses a snap-fit coupling where the housing sections are designed to interlock and separate through vertical movement, inverting the traditional fastening approach

Inventive Principle:

Principle #13The other way round (Inversion)

2Ease of repair

If traditional coupling tools are repeatedly coupled and disassembled, then the housing can be serviced, but the screw threads become worn and damaged

Engineering Contradiction:

ImproveserviceabilityVSAvoidthread durability

Core Design Contradiction:

Ease of repairVSReliability

Solution Approach 1:

The coupling protrusion and recess are designed as wear-resistant permanent features of the housing structure itself, eliminating the need for reusable threaded fasteners that degrade with repeated use. The housing sections can be serviced multiple times without cumulative wear damage

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Ease of operation

If the housing is disassembled through complex processes, then internal parts can be accessed, but the risk of damage to internal parts increases

Engineering Contradiction:

Improveaccess to internal partsVSAvoidrisk of internal part damage

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The coupling recess includes a guide structure that preliminarily guides the separation force in the vertical direction before the housing sections fully separate, ensuring controlled disassembly that prevents accidental damage to internal components

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The coupling mechanism acts as an intermediary that mediates the separation process, providing a controlled interface between the upper and lower housing sections that allows safe access to internal parts without direct manual manipulation that could cause damage

Inventive Principle:

Principle #24Intermediary (Mediator)

4Stability of the object's composition

If multiple coupling tools are used to secure the housing, then the assembly is stable, but the device complexity increases

Engineering Contradiction:

Improvehousing stabilityVSAvoidcoupling mechanism complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The coupling function is merged into the housing structure itself through integrated coupling protrusions and recesses, eliminating the need for separate coupling tools and simplifying the overall device structure while maintaining assembly stability

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The housing sections serve multiple functions: they provide structural enclosure and simultaneously incorporate the coupling mechanism, making the housing itself multi-functional and reducing the number of separate components needed

Inventive Principle:

Principle #6Universality (Multi-functionality)
