Rotary Logo Positioning Mechanism With Multi-Angle Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotation mechanisms in electronic products do not allow for flexible positioning of brand logos, limiting user experience by restricting the ability to freely change the logo's orientation.
Innovation Solution
A rotation mechanism comprising a rotary base, a rotary set, a securing set, and an elastic set, which enables multi-directional locking positions through gear teeth and ratchet teeth structures, allowing for adjustable spacing and elastic force compensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed brand logo position is used on electronic products, then the manufacturing process is simple and the structure is stable, but the adaptability and user experience are limited due to inability to freely change logo orientation
Solution Approach 1:
The rotation mechanism is divided into independent functional modules: a rotary base for mounting, a rotary set with gear teeth for positioning, slide portions for engagement, and an elastic set for force compensation. This segmentation allows each component to perform its specific function while maintaining overall system adaptability without excessive complexity.
Solution Approach 2:
The mechanism transitions from a static fixed logo position to a dynamic multi-position rotatable structure. The rotary set can rotate relative to the rotary base and lock at multiple predetermined positions defined by gear tooth engagements, enabling the brand logo to be freely oriented while maintaining stability at each position.
2Adaptability or versatility
If a rotatable structure with multiple locking positions is implemented, then the adaptability and user experience are improved, but the device complexity and structural difficulty increase
Solution Approach 1:
Multiple functions are merged into compact structures: the slide portions integrate both positioning (through gear tooth engagement at predetermined positions) and spacing adjustment (through relative sliding motion) functions. The elastic set simultaneously provides force compensation and maintains engagement pressure, reducing the need for separate components.
Solution Approach 2:
The mechanism uses self-contained features for positioning and locking. The gear teeth on the rotary set and corresponding engagement features on the rotary base create automatic locking at predetermined positions without requiring external actuators or complex control systems. The elastic set automatically compensates for dimensional variations and maintains engagement force.
3Length of moving object
If the spacing between rotary set and rotary base is increased for rotation movement, then the rotation range is improved, but the structural stability and positioning precision may deteriorate
Solution Approach 1:
The mechanism allows the spacing parameter between the rotary set and rotary base to dynamically change. During rotation, the slide portions slide relative to each other, increasing the spacing to enable rotation movement. At locked positions, the gear tooth engagement establishes precise spacing, ensuring positioning accuracy is maintained at each predetermined position.

AI summary
A rotation mechanism having a positioning function includes a rotary base, a rotary set rotatably arranged on the rotary base, a securing set mounted on the rotary set for adjusting a spacing between the rotary set and the rotary base, and an elastic set mounted between the securing set and the rotary set and butted against by the securing set for providing an elastic force. The rotary case includes a fix pin extending from the rotary base and a first slide portion portion disposed on the rotary base and configured around the fix pin. The rotary set includes a second slide portion correspondingly engaged with the first slide portion, and a first opening used for receiving the fix pin and allowing the rotary set being rotated relative to the rotary base.
