Extendable Non-Break Plates for Bottle Cap Distance Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottle caps with non-breakable plates have limited distance adjustment and insufficient support, leading to potential breakage when mounting or removing the cap from a bottle opening.
Innovation Solution
The bottle cap design features extendable non-breakable plates with multiple turning positions and angles, ensuring the cap is securely connected without breaking, allowing for increased distance between the cap body and security ring for easy dismounting and re-capping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the non-breakable plates have a fixed single angle between first and second inclined portions, then the structure is simple, but the distance adjustment between body and security ring is limited
Solution Approach 1:
The non-breakable plates are designed with multiple turning positions and adjustable angles between the first and second inclined portions. This allows the angle to be dynamically changed during operation, enabling the body to move to different distances from the security ring while maintaining structural support.
2Device complexity
If the non-breakable plates are not sufficiently supported, then the device complexity is reduced, but the plates may break when the body is mounted to the bottle opening
Solution Approach 1:
The non-breakable plates are provided with ribs that extend along the plates, creating localized reinforcement zones. These ribs increase the moment of inertia and bending resistance specifically where needed, preventing plate breakage during mounting and operation without requiring a completely different plate design.
3Quantity of substance
If the width of connection portions is equal to the width of non-breakable plates, then the material usage is optimized, but the top and bottom ends of plates are prone to breaking
Solution Approach 1:
The connection portions are designed with a width greater than the non-breakable plates, creating an overlapping region. This provides beforehand support and stress distribution at the critical plate ends, preventing breakage before it can occur during mounting or operation.
4Stability of the object's composition
If the body is closely connected to the security ring, then the structural stability is improved, but the ease of dismounting and re-capping is reduced
Solution Approach 1:
The adjustable angle mechanism allows the non-breakable plates to be positioned at different angles, dynamically changing the distance between the body and security ring. This enables the system to provide close connection for stability when needed, and increased distance for ease of dismounting and re-capping when needed.

AI summary
A bottle cap includes a body (10) and a security ring (20). The body has multiple breakable bridge portions (21) located along the periphery of the body (10) and connected to the security ring (20). Two non-breakable plates (50) are connected between the body (10) and the security ring (20). Each of the non-breakable plates (50) includes multiple turning positions and multiple angles. When the multiple breakable bridge portions (21) are broken, the non-breakable plates (50) are still connected to the security ring (20). The non-breakable plates (50) are extendable so that the body (10) can be pulled away from the security ring (20) for a distance.
