Imaging Apparatus Sheet Fixing Member for Contact Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses face challenges in achieving normal contact between members with shape variations due to the need for high precision in fabricating attachment surfaces, which is difficult to achieve consistently.
Innovation Solution
An imaging apparatus design that includes a casing with attachment surfaces, a sheet fixing member with displaceable portions, and a flexible circuit board, allowing for normal contact even with shape variations by using a sheet-like member between the casing and the sheet-fixing member, where the sheet fixing member has first and second contact surfaces that can adjust to accommodate variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple attachment surfaces are fabricated with high precision, then normal contact between members is achieved, but manufacturing complexity and cost increase significantly
Solution Approach 1:
The sheet fixing member incorporates a flexible portion that can dynamically adjust its position and shape to accommodate variations in attachment surfaces. This dynamic flexibility allows the member to maintain normal contact with multiple attachment surfaces without requiring each surface to be fabricated with high precision, thereby resolving the contradiction between contact reliability and manufacturing ease
Solution Approach 2:
The invention changes the physical state of the sheet fixing member by introducing a flexible portion that can deform elastically. This parameter change from rigid to flexible allows the member to adapt to surface variations through elastic deformation, achieving reliable contact while simplifying the manufacturing requirements of the attachment surfaces
2Manufacturing precision
If both members are fabricated with high precision and without shape variations, then proper contact is achieved, but manufacturing difficulty and cost increase
Solution Approach 1:
The sheet fixing member uses a thin flexible film structure that can bend and deform to compensate for shape variations in both itself and the attachment surfaces. This flexible thin film approach eliminates the need for high manufacturing precision while ensuring proper contact between members
Solution Approach 2:
The flexible portion of the sheet fixing member introduces dynamic adaptability, allowing the structure to adjust its shape during assembly and operation. This dynamic capability compensates for manufacturing tolerances and shape variations, achieving proper contact without requiring both members to be fabricated with high precision

AI summary
An imaging apparatus includes: a casing having first and second attachment surfaces; a sheet fixing member having first and second contact surfaces coming into contact with the first and second attachment surfaces, respectively; and a sheet-like member disposed between the casing and the sheet fixing member. The sheet fixing member has a first portion and a second portion that is displaceable with respect to the first portion. The first contact surface of the sheet fixing member is disposed on the first portion. The second contact surface of the sheet fixing member is disposed on the second portion.
