Pressing Member Slope Surface Reduces Operational Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses require high operational force to move detachable bodies from a first position to a second position due to perpendicular contact surfaces, leading to inefficient operation and potential misalignment issues.
Innovation Solution
The image forming apparatus incorporates a pressing member with a slope surface forming an obtuse angle with the pressing surface, which contacts the detachable body to facilitate smooth movement from the first to the second position, reducing operational force and ensuring proper alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a detachable body is moved from a first position to a second position with a surface perpendicular to the pressing surface, then the positioning is straightforward, but the operational force required is high
Solution Approach 1:
The pressing member is equipped with a slope surface instead of a perpendicular contact surface. This inclined surface allows the detachable body to be guided smoothly into the second position, reducing the operational force required by the user while maintaining positioning accuracy.
Solution Approach 2:
The contact surface geometry is changed from a simple perpendicular interface to an inclined surface that introduces a directional component. This dimensional change in the contact interface allows the pressing member to both push and guide the detachable body simultaneously, reducing operational force.
2Ease of operation
If a pressing member with a slope surface is used to reduce operational force, then ease of operation improves, but the device structure becomes more complex
Solution Approach 1:
The slope surface is integrated directly into the pressing member structure, combining the positioning and pressing functions into a single component. This merging eliminates the need for separate guiding surfaces or additional mechanical elements, thereby reducing overall device complexity while maintaining ease of operation.
