Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic apparatuses, such as laptops and all-in-one computers, lack a foolproof mechanism to ensure proper alignment and storage of functional units like lens units, which can be misaligned when returned to their casing.
Innovation Solution
A rotation resetting device comprising a functional unit, a limiting block with a taper chute, and an elastic unit, allowing the functional unit to move between a use and storage position, utilizing a fan-shaped limiting gasket and taper chute to compress and restore the unit to a preset angle, with optional electromagnet and magnet for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the functional unit is allowed to rotate freely for user convenience, then ease of operation is improved, but alignment precision deteriorates due to potential misalignment during storage
Solution Approach 1:
The taper chute is pre-configured with a specific angular slope that automatically guides the limiting gasket to the correct preset angle during the storage process. As the functional unit rotates into the accommodating space, the limiting gasket slides along the predefined taper path, which preliminarily determines the final alignment position without requiring user intervention or additional sensing mechanisms.
Solution Approach 2:
The system uses self-service alignment where the limiting gasket interacts with the taper chute geometry to automatically reset itself to the preset angle. The elastic unit provides self-restoring force that pushes the limiting gasket along the taper chute, and the taper's angular configuration ensures the gasket naturally settles at the correct orientation, eliminating the need for external control systems.
2Manufacturing precision
If a foolproof mechanism is added to prevent misalignment, then alignment precision is improved, but device complexity increases
Solution Approach 1:
The alignment control function is extracted from complex active control systems and embodied in the passive geometric structure of the taper chute. Instead of using sensors, motors, or control algorithms to manage alignment, the patent extracts the alignment function into the simple angular geometry of the taper chute, which inherently guides the limiting gasket to the correct position through its shape alone.
Solution Approach 2:
The limiting gasket serves as an intermediary element between the functional unit and the taper chute. It transfers the rotational motion of the functional unit into linear sliding motion along the taper chute, and simultaneously transmits the elastic restoring force from the elastic unit to drive the reset action. This intermediary mechanism simplifies the overall system by using a simple mechanical interface rather than complex control systems.
3Ease of operation
If the functional unit is pressed to protrude for use, then ease of operation is improved, but reliability deteriorates due to potential misalignment when returning to storage
Solution Approach 1:
The taper chute provides geometric feedback that automatically corrects any misalignment. As the functional unit rotates into the accommodating space, the limiting gasket's interaction with the taper chute's angular surface provides continuous positional feedback, ensuring the unit is guided back to the preset angle. The elastic unit also provides force feedback by pushing the limiting gasket along the taper path, creating a self-correcting mechanism that ensures reliable alignment.

AI summary
A rotation resetting device and an electronic apparatus are provided. The rotation resetting device includes a functional unit, a limiting block and an elastic unit. The functional unit includes a functional element and a supporting element connected to the functional element, wherein the supporting element includes a limiting gasket. The limiting block has an accommodating space with an opening and a taper chute extending downward from the opening. The elastic unit is located in the accommodating space and connected between the limiting block and the functional unit. The functional unit is movably disposed in the accommodating space and is capable of moving between an use position and a storage position relative to the opening. When the functional unit moves from the use position to the storage position, the limiting gasket abuts the taper chute, and rotates and slides downward along the taper chute while compressing the elastic unit.
