Innovation Solution
A 360-degree rotatable accessory design featuring a body with an insertion groove and slots, an outer gear with projections, an inner gear with teeth, a spring for elastic support, and a rotary guider, allowing for 360-degree rotation and secure angle maintenance through engagement and disengagement of gears, or alternative designs using threads and contact plates for thread-fastening, enabling transformation into various shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the accessory uses a fixed structure, then the manufacturing cost is reduced and the structure is simple, but the versatility and commercial value are low because it cannot be rotated or transformed into various shapes
Solution Approach 1:
The accessory incorporates a rotatable coupling portion that enables dynamic rotation of 360 degrees, allowing the accessory to transform into various shapes and orientations. This dynamic mechanism resolves the contradiction by providing versatility through rotation while maintaining a relatively simple overall structure consisting of a body, coupling portion, and rotational mechanism.
Solution Approach 2:
The rotatable coupling portion serves multiple functions: it enables rotation for shape transformation, provides angle maintenance through engagement structures, and allows the accessory to be used in various configurations. This multi-functionality increases versatility without proportionally increasing structural complexity.
2Adaptability or versatility
If the accessory allows 360-degree rotation, then the commercial value and versatility are improved, but the structure becomes more complicated and manufacturing cost increases
Solution Approach 1:
The rotational mechanism uses a coupling portion with engagement structures (protrusions and grooves) that enable 360-degree rotation while maintaining position at desired angles. This dynamic capability enhances commercial value by allowing the accessory to be displayed and used in multiple orientations without requiring complex multi-component assemblies.
Solution Approach 2:
The engagement structures in the rotational mechanism automatically maintain the rotated position through mechanical engagement, eliminating the need for additional motors, sensors, or control systems. This self-servicing mechanism achieves 360-degree rotation and angle maintenance with minimal added manufacturing complexity.
3Adaptability or versatility
If the accessory uses a fixed coupling portion, then the structure is simple and manufacturing is easy, but the accessory cannot be rotated or transformed into various shapes
Solution Approach 1:
The coupling portion is designed with rotational capability through engagement structures including protrusions and grooves that allow 360-degree rotation while maintaining mechanical connection. This dynamic coupling enables shape transformation without requiring complex multi-part assemblies or additional fastening mechanisms.
Solution Approach 2:
The coupling portion acts as an intermediary element between the body and the accessory, providing rotational freedom while maintaining secure connection. The engagement structures serve as the mediating mechanism that enables rotation and shape transformation without increasing overall structural complexity.
