Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire holding members in image forming apparatuses are bulky, require specialized tools for manufacturing, and have low work efficiency due to their three-dimensional structure, making them difficult to attach and store effectively.
Innovation Solution
A wire holding structure comprising an elastic sheet member with bent holding pieces formed by curved or bent cuts, allowing easy attachment to a sheet-metal frame with a stepped portion, which supports the wire holding member and enables efficient wire management without the need for complex bending tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional three-dimensional wire holding member is used, then wire holding function is achieved, but the structure becomes bulky and difficult to store
Solution Approach 1:
The wire holding member is transformed from a three-dimensional structure to a two-dimensional flat sheet structure. The holding pieces are formed by making cuts in a flat sheet member, allowing the entire structure to be stored in a compact, flat state and only becoming three-dimensional when attached to the frame for wire holding operations.
Solution Approach 2:
The invention uses a flat sheet member as the base structure for the wire holding member. This thin film approach allows the holding member to be stored compactly while still providing sufficient structural integrity when installed, resolving the contradiction between functionality and storage compactness.
2Reliability
If a three-dimensional wire holding member is manufactured, then wire holding capability is provided, but specialized bending tools are required
Solution Approach 1:
The wire holding member is segmented into multiple holding pieces formed by cuts in the flat sheet. Each holding piece is created by making a cut from the edge toward the center, dividing the sheet into functional segments that can be bent and attached without requiring complex three-dimensional forming tools.
Solution Approach 2:
The invention changes the structural parameter from three-dimensional to two-dimensional, allowing standard cutting and bending tools to be used instead of specialized three-dimensional forming equipment. The holding pieces are created through simple cuts and bending operations on a flat sheet.
3Reliability
If a conventional wire holding member is attached, then wire management is achieved, but work efficiency is reduced due to complex attachment process
Solution Approach 1:
By transforming the holding member to a two-dimensional flat structure, the attachment process is simplified. The flat sheet can be easily positioned and attached to the frame, and the holding pieces can be bent into place without complex assembly steps, thereby improving work efficiency while maintaining wire management functionality.

AI summary
A wire holding structure includes a wire holding member and a support member. The wire holding member is formed from an elastic sheet member, includes a holding piece that can be bent in a direction perpendicular to a surface of the sheet member and is formed by forming a curved cut or a bent cut, and is configured such that a wire can be held in a gap that is formed when the holding piece is bent. The support member constitutes a part of a plate-like frame that constitutes a housing of an image forming apparatus. The support member includes a stepped portion and supports the wire holding member on an upper stage surface of the stepped portion in a state where the cut of the holding piece is oriented toward an edge of the upper stage surface, and a tip of the holding piece projects over the edge.
