Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing cell box technologies require complex operations for fixing and releasing printed circuit boards, which complicates the packing and unpacking process.

Innovation Solution

A cell box design featuring a spacer that can be switched between two states, allowing for simple operation to fix and release the object to be packed, by adjusting its protrusion from the sidewall.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an engagement member with multiple arms is used to fix the printed circuit board, then the printed circuit board can be securely fixed, but the operations for fixing and releasing become complicated

Engineering Contradiction:

Improvefixing reliabilityVSAvoidoperation complexity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The engagement member is divided into a first engagement member that engages with the display panel and a second engagement member that engages with the printed circuit board. These two engagement members are connected through a rotating member, allowing them to operate independently. This segmentation enables simple single-action operation while maintaining reliable fixing of both components.

Inventive Principle:

Principle #1Segmentation

2Reliability

If a first arm and second arm are inserted into separate engagement grooves and notch portions, then the printed circuit board can be fixed, but the fixing and releasing operations become complicated

Engineering Contradiction:

Improvefixing reliabilityVSAvoidoperation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The first engagement member and second engagement member are combined into a single integrated engagement member structure. By rotating the rotating member, both engagement members can be engaged or disengaged simultaneously through a single operation, reducing the time required for fixing and releasing while maintaining reliable fixation.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If the spacer protrudes by a first distance from the sidewall, then the object to be packed can be fixed, but the structure becomes more complex

Engineering Contradiction:

Improvefixing reliabilityVSAvoidstructure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The spacer is designed to be movable relative to the sidewall, allowing it to switch between protruding by a first distance (for fixing) and protruding by a second distance or not protruding at all (for releasing). This dynamic adjustment capability enables simple operation while maintaining fixing reliability when needed.

Inventive Principle:

Principle #15Dynamics

AI summary

A cell box includes a bottom plate on which an object to be packed is placed, a sidewall formed at a peripheral edge of the bottom plate, and a spacer that is switched between a first state where one end of the spacer protrudes by a first distance from a sidewall toward a side of an accommodation space accommodating the object to be packed, and a second state where the one end does not protrude from the sidewall toward the side of the accommodation space.
