Solution Overview

Problem

Existing accommodating devices for plate-shaped members, such as electronic substrates and printed circuit boards, face inefficiencies in mounting and replacing segments due to integral slot designs leading to high replacement costs and time-consuming assembly processes.

Innovation Solution

The design features a modular system with segments that have engagement portions for connection and loosely-fitting units for easy detachment and mounting on a wall body, allowing for efficient stacking and replacement of accommodating portions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If slots are molded integrally into one member, then the accommodating portions are firmly fixed and reliable, but the cost for replacing components becomes high when damage occurs

Engineering Contradiction:

Improvefirm fixation of accommodating portionsVSAvoidreplacement cost of damaged components

Core Design Contradiction:

ReliabilityVSEase of repair

Solution Approach 1:

The side plate is divided into multiple independent slots that can be separately replaced. Each slot is a separate component that can be detached and replaced individually without replacing the entire side plate, thus reducing repair costs while maintaining reliable fixation through the modular design

Inventive Principle:

Principle #1Segmentation

2Reliability

If rail member is firmly fixed by plurality of claws one by one, then the rail member is reliably attached to wall surface, but mounting and assembling work takes time

Engineering Contradiction:

Improvereliable attachment of rail memberVSAvoidmounting work efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

Multiple claws are integrated into a single claw member that can be attached to the wall surface in one operation. This merging of multiple fixation elements into one component maintains reliable attachment while significantly reducing mounting time and improving productivity

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If rail member uses complex claw system for fixation, then firm attachment is achieved, but the rail member is not easily removed and replaced

Engineering Contradiction:

Improvefirm attachmentVSAvoidease of removal and replacement

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The claw member is designed with dynamic fixation capability, allowing it to be firmly attached during mounting but easily released during removal. The claw structure enables one-handed operation for both attachment and detachment, providing firm fixation when needed while maintaining ease of replacement

Inventive Principle:

Principle #15Dynamics
