Cover Sequence Regulation Mechanism for Image Formation Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image formation apparatuses require more effort to properly open and close their covers due to incorrect opening/closing sequences, affecting operability.
Innovation Solution
A covers opening/closing sequence regulation system that allows the first cover to be opened and closed while the second cover is fully closed, and prevents the second cover from being opened or closed when the first cover is fully closed, using a regulation mechanism to stop the first cover in a spaced-out position, ensuring the second cover can be opened and closed independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the opening/closing sequence of covers is regulated to allow proper maintenance access, then maintenance services can be properly provided, but the operability deteriorates when covers are opened/closed in wrong sequence requiring more effort
Solution Approach 1:
The regulation mechanism performs preliminary action by stopping the first cover at a spaced-out position before full closure when the second cover is open. This preliminary positioning prevents the need for users to manually adjust cover sequences during maintenance operations, allowing maintenance access while maintaining ease of operation through automated sequence control
Solution Approach 2:
The regulation mechanism acts as an intermediary between the two covers, mediating their opening/closing sequences. It detects when the second cover is open and automatically positions the first cover at a spaced-out state, eliminating the need for users to manually coordinate cover sequences and thereby improving both maintenance access and operational ease
2Adaptability or versatility
If the first cover is stopped in a spaced-out position to allow second cover operation, then the second cover can be opened and closed independently, but the first cover cannot be fully closed when second cover is open
Solution Approach 1:
The regulation mechanism employs self-service through automatic detection and response. When the second cover is detected as open, the mechanism automatically stops the first cover at a spaced-out position without requiring external control or complex coordination systems. This self-regulating behavior enables independent cover operation while minimizing added complexity
Solution Approach 2:
The regulation mechanism merges the control functions of both covers into a single integrated system. By combining the detection of second cover state with the positioning control of the first cover, the system achieves versatile independent operation without proportionally increasing device complexity, as the control logic is unified rather than separate

AI summary
A covers opening/closing sequence regulation system includes a first cover and a second cover openably and closably attached to a housing. The first and second covers are provided in a way that the first cover becomes openable and closable while the second cover is in a fully-closed state, and that the second cover becomes unable to be fully-closed from an opened state while the first cover is in a fully-closed state. A regulation mechanism is configured to stop the first cover in a spaced-out position, which is spaced out from a fully-closed position of the first cover, in an operation of closing the first cover toward the fully-closed position with the second cover being in an opened state. The second cover is openable and closable while the first cover is in the spaced-out position.
