Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing accessories, such as jewelry and bag decorations, have high manufacturing costs and low commercial value due to complex structures and fixed coupling portions that restrict their versatility and rotation.
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 embodiments using threads and contact plates for thread-fastening and rotation control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed coupling structure is used, then the manufacturing cost is reduced, but the accessory cannot be rotated and has low versatility
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed coupling structure into a rotatable one. The accessory body is designed with a rotation guide groove and rotation guide protrusions that allow the accessory to rotate 360 degrees around the coupling portion, while the spring-loaded contact plates provide dynamic locking/unlocking functionality. This enables the accessory to adapt to different wearing positions and orientations, significantly improving versatility without excessive structural complexity.
Solution Approach 2:
The patent segments the coupling structure into distinct functional components: the coupling portion with threads, the rotation guide groove, the contact plates, and the spring mechanism. This segmentation allows each component to perform its specific function independently while working together as a unified system, enabling rotation capability without requiring a completely complex redesign of the entire accessory structure.
2Adaptability or versatility
If a complex structure with multiple parts is used, then the accessory can be replaced freely, but the manufacturing cost is high and productivity is low
Solution Approach 1:
The patent applies universality by designing a multi-functional coupling structure that combines jewel replacement, rotation, and securing functions into a single integrated mechanism. The coupling portion with threads allows easy jewel replacement, while the rotation guide groove and contact plates simultaneously provide rotation capability and secure locking. This multi-functionality eliminates the need for separate mechanisms for each function, reducing the number of parts and simplifying manufacturing.
Solution Approach 2:
The patent merges multiple functions into the coupling structure: the threaded coupling provides both jewel attachment and rotation capability, while the spring-loaded contact plates combine locking and positioning functions. By merging these functions into unified components rather than separate mechanisms, the patent reduces part count and manufacturing complexity while maintaining versatility.
3Adaptability or versatility
If a rotatable mechanism is added, then the accessory can be transformed into various shapes, but the device complexity increases
Solution Approach 1:
The patent implements dynamics through the rotatable coupling mechanism that allows the accessory to rotate 360 degrees and be positioned at various angles. The rotation guide groove guides the rotation path, while the spring-loaded contact plates dynamically adjust to lock the accessory at any desired position. This dynamic capability enables shape transformation without requiring complex mechanical joints or multiple locking points.
Solution Approach 2:
The patent uses the rotation guide groove as an intermediary element that mediates between the fixed coupling portion and the rotatable accessory body. The groove provides a defined path for rotation, guiding the movement and ensuring smooth operation. This intermediary structure simplifies the overall mechanism by providing a straightforward rotational guide rather than requiring complex joints or bearings.
