Flower-Like Opening Mechanism for Small Decorations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing accessories and decorations with opening/closing mechanisms are often complex, difficult to mount on small items, and lack smooth operation and maintainability, especially when trying to replicate a flower-like opening/closing motion.
Innovation Solution
A simple rotationally symmetric mechanism using a group of operation bases and petal-shaped parts with integrated rotation shafts, where the operation bases form a spherical surface and overlap to create a smooth, synchronous opening/closing motion with minimal components, allowing for easy application to small items like rings and brooches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional opening/closing mechanisms are used in accessories, then the mechanism can achieve opening/closing function, but the structure becomes complicated and requires many components
Solution Approach 1:
The mechanism is divided into multiple identical operation bases arranged rotationally symmetrically, each controlling one petal-shaped part. This segmentation allows the complex opening/closing function to be achieved through repetition of simple modular units, reducing overall structural complexity while maintaining reliability
Solution Approach 2:
Multiple operation bases are merged into a unified rotational system where rotating one base synchronously moves all other bases through their overlapping contact. This merging consolidates multiple independent mechanisms into a single coordinated system, simplifying the overall structure
2Reliability
If traditional opening/closing mechanisms are used in accessories, then the mechanism can achieve opening/closing function, but it is difficult to mount on small accessories and design freely
Solution Approach 1:
The mechanism uses multiple small, identical operation bases that can be arranged in rotationally symmetric patterns suitable for small accessories like rings. Each base-petal unit is compact and can be scaled to fit various accessory sizes while maintaining the opening/closing function
Solution Approach 2:
The operation bases are designed with universal characteristics - they can be arranged in different rotational configurations (5-petal, 6-petal, etc.) and applied to various accessory types (rings, brooches, decorations) while maintaining the same fundamental mechanism, enabling free design adaptation
3Reliability
If traditional opening/closing mechanisms are used in accessories, then the mechanism can achieve opening/closing function, but the operation is not smooth and maintainability is insufficient
Solution Approach 1:
The operation bases are designed with curved surfaces that form a spherical arrangement, allowing smooth rotational movement. The curved contact surfaces between overlapping bases enable continuous, friction-reduced motion compared to traditional angular or flat-contact mechanisms
Solution Approach 2:
The mechanism transitions from static, independently moving parts to a dynamic system where all operation bases move synchronously through rotational coupling. This dynamic coordination ensures smooth, coordinated motion of all petal-shaped parts simultaneously, improving operational fluidity
4Adaptability or versatility
If rotation mechanism is added to decoration to make it open like a flower, then the decoration becomes innovative and gives surprise, but the structure becomes unnecessarily complex
Solution Approach 1:
The flower-like opening effect is achieved by segmenting the decoration into multiple petal-shaped parts that can be independently positioned. Each petal is controlled by a simple operation base, creating the innovative floral motion through repetition of basic units rather than a complex integrated mechanism
Solution Approach 2:
The petal-shaped parts are designed with asymmetric forms that naturally create the flower-like appearance when arranged rotationally. The asymmetric geometry of petals combined with their synchronous rotational movement produces the innovative visual effect without requiring additional complex mechanisms

AI summary
As a new design, when making part of a decoration rotatable, there is a tendency for this to result in an unnecessarily complex structure, and it was difficult to apply such structures to small decorations such as rings, due to considerations such as strength and smooth movement. Solution: The present invention was configured as follows in order to provide a decoration which, even if having a small size, has a simple structure and strength, and opens like a flower. The decoration has a configuration whereby one of a group of movable petals (1) having a calculated curved surface (2) and which are positioned so as overlap with the positions to be rotated and are synchronized with one another, is opened and closed by a single rotating knob (11) and is synchronized with the other petal-shaped parts (1) smoothly and effectively to replicate the movement of a flower opening and closing.
