Sliding-Rotating Cover Mechanism for Collision-Safe Casing Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cover mechanisms for electronic apparatus casings, typically using lifting and rotating doors, pose risks of collision damage and reveal aesthetic defects on the inner surfaces, compromising both functionality and appearance during maintenance or device replacement.
Innovation Solution
A sliding and rotating cover mechanism that keeps the inner door surface facing the casing body, allowing the door to slide and rotate while maintaining an aesthetic appearance by using a pivotal device and pivot locking mechanism, preventing the door from being visible and vulnerable during operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the door is opened by lifting and rotating, then the user can manipulate the equipment, but the door may collide with the user causing damage to the door or device unit
Solution Approach 1:
The door opening motion is segmented into two distinct phases: first sliding horizontally along the guiding structure, then rotating around the pivotal device. This segmentation separates the access function from the potential collision risk, as the door moves away from the user's manipulation area before rotating open.
Solution Approach 2:
The guiding structure acts as an intermediary mechanism between the door and the pivotal device. It controls and constrains the door's initial movement path, ensuring the door slides in a predetermined direction away from the manipulation area before engaging with the pivotal device for rotation.
2Ease of operation
If the door is opened by lifting and rotating, then the user can access the equipment, but the inner surface of the door with appearance defects becomes visible
Solution Approach 1:
Instead of the conventional approach where the door's outer surface remains visible when open, this invention inverts the configuration so that the inner surface (with appearance defects) faces outward when the door is in the open position. The guiding structure and pivotal device arrangement ensures the door rotates in a direction that presents the imperfect inner surface to the external view.
Solution Approach 2:
The door's orientation is changed from the conventional vertical opening to a horizontal slide followed by rotation. This dimensional change in the opening trajectory allows the inner surface to be positioned facing outward when open, while still providing adequate access to the manipulation area through the sliding motion.
3Shape
If the door is slid and rotated to keep the inner surface facing the casing body, then the aesthetic appearance is maintained, but the door mechanism becomes more complex
Solution Approach 1:
The guiding structure and pivotal device are merged into an integrated assembly where the guiding structure provides both the sliding constraint and the positioning for the pivotal device. This merging reduces the number of separate components and simplifies the overall mechanism while achieving the desired door motion path.
Solution Approach 2:
The guiding structure serves multiple functions: it constrains the door's sliding motion, positions the door relative to the pivotal device, and guides the door's rotation path. This multi-functionality reduces the need for additional separate mechanisms, thereby limiting the increase in device complexity.

AI summary
An electronic apparatus includes an apparatus casing, using a cover mechanism, and a device unit, disposed inside the apparatus casing. The apparatus casing includes a casing body, a pivotal device, a pivot locking mechanism, and a door. The casing body structurally constrains the door to move in a direction at a side of the casing body. After sliding, the door is engaged with the pivotal device and drives the pivot locking mechanism to unlock the pivotal device so that the door can rotate to another side of the casing body by the pivotal device relative to the casing body. A manipulation area of the casing body is therefore exposed. Thereby, a user can manipulate the device unit through the manipulation area; the inner surface of the door keeps facing toward the casing body so that the apparatus casing can keep its aesthetic appearance.
