Cover Biasing Mechanism for Balanced Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face challenges in easily opening and closing the cover without damaging it, as the biasing assembly can cause bending when pushed closed from one side.
Innovation Solution
The use of biasing assemblies in the side walls of the housing, combined with a locking assembly and interlock switch, allows the cover to be easily opened by releasing the locking mechanism and utilizing compression coil springs to maintain torque for balanced opening and closing, preventing oblique orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a locking assembly is released to allow the cover to be opened, then the cover becomes easily openable by the user, but the cover may be pushed closed from one side causing bending damage
Solution Approach 1:
The biasing force is segmented into multiple independent biasing assemblies distributed at different positions on the housing. Each biasing assembly independently applies force to specific regions of the cover, ensuring balanced support and preventing localized bending when the cover is pushed closed.
Solution Approach 2:
Different regions of the housing are equipped with biasing assemblies at strategically selected positions to provide localized biasing forces. This ensures that each area of the cover receives appropriate support tailored to its specific structural requirements and loading conditions.

AI summary
An image forming apparatus including a housing, a cover, an interlock switch, a locking assembly, and a biasing assembly. The housing may comprise a pair of frames spaced apart from each other, and may form an opening between the pair of frames. The cover may move between a covered position wherein the opening is covered and an opened position wherein the opening is uncovered. The interlock switch may be pressed by the cover when the cover is in the covered position. The locking assembly may move between a locking state wherein the locking assembly locks the cover in the covered position and a released state wherein the locking assembly allows the cover to move. Further, the biasing assembly may be positioned in or on at least one of the frames, and may bias the cover toward the opened position when the cover is in the covered position.
