Fixing Member Bending Deformation for Operation Panel Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face challenges in efficiently and easily replacing the function display sheets and transparent cover members on their operation panels, particularly due to the complexity and user burden of the fixing mechanisms, which often require nails and forceful detachment.
Innovation Solution
The design incorporates a fixing member with a slidably moving fixing body and engaging parts that allow for easy detachment by bending deformation, reducing the need for nails and simplifying the detachment process, enabling straightforward replacement of the display plate and transparent cover member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional fixing member with abutting piece and shaft is used to fix the transparent cover member, then the fixing strength is improved, but the ease of operation for detachment deteriorates due to requiring nails and forceful detachment
Solution Approach 1:
The fixing member transitions from a static rigid structure to a dynamic system where the fixing body can elastically deform. The elastic portion bends to release engagement with the operation panel, enabling easy detachment without requiring external tools or forceful actions, thus resolving the contradiction between strong fixing and easy detachment
Solution Approach 2:
The physical state of the fixing member changes through elastic deformation. By changing the bending parameter of the elastic portion, the engagement state between the fixing member and operation panel is reversed from engaged to disengaged, allowing simple detachment while maintaining strong fixing during normal operation
2Reliability
If a rigid fixing structure is used to ensure stable fixing, then the reliability of fixing is improved, but the ease of manufacture deteriorates due to complex assembly requirements
Solution Approach 1:
The fixing member is segmented into distinct functional portions: a fixing body for engagement, an elastic portion for flexible connection, and a projection piece for positioning. This segmentation allows each part to be manufactured independently and simplifies the overall assembly process while maintaining reliable fixing through the coordinated function of these segments
Solution Approach 2:
The elastic portion acts as a flexible element that provides both structural integrity for reliable fixing and manufacturing simplicity. The flexibility allows the fixing member to be easily assembled and detached without complex mechanisms, while still ensuring stable fixation during operation

Function Achieved in This Case
This solution facilitates stable and easy detachment of the fixing member from the operation panel, reducing user burden and improving the stability of the detachment process, allowing for effortless replacement of the display and cover components.
Implementation Method 1
when the one side end portion of the straight line direction of the fixing body is pressed downward and is subjected to bending deformation, engagement of the first engaging part and the first part to be engaged is released due to the bending deformation

AI summary
A fixing member has a fixing body, which slidably moves in a straight line direction, and a first engaging part. The first engaging part projects downward from a lower surface of the fixing body to pass through an operation panel. The first engaging part is engaged with a part to be engaged formed on a lower surface of the operation panel, thereby restricting the fixing body so as not to move in the straight line direction. A space is formed in a height direction between one side end portion in the straight line direction of the fixing body and the upper surface of the operation panel. When the one side end portion in the straight line direction of the fixing body is pressed downward and is subjected to bending deformation, engagement of the first engaging part and the part to be engaged is released.
