Protection Cap Assembly for Bolt Shanks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices, such as bolts, expose their shanks, affecting aesthetics and requiring time-consuming and force-intensive cutting, which can damage the substrate.
Innovation Solution
A protection cap assembly comprising a clipping ring, gripping shaft with set screws, channels, and fins, and a cap made from materials like acrylonitrile butadiene styrene, designed to easily fit over bolts of various sizes, providing a safe and aesthetically pleasing solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the bolt shank is left exposed after fastening, then the fastening function is achieved, but the aesthetics are degraded and cutting becomes time-consuming and force-intensive
Solution Approach 1:
The protection cap is fitted over the bolt shank immediately after fastening, before any cutting operation is attempted. This preliminary action of covering the bolt prevents the need for subsequent cutting operations, saving time and avoiding substrate damage.
Solution Approach 2:
The invention extracts the problematic exposed bolt shank from view by introducing a protection cap that covers it. The cap is designed to fit over the bolt and can be easily installed without requiring cutting or modification of the substrate.
2Ease of operation
If heavy force is applied to cut the exposed bolt, then the bolt can be removed, but the substrate surface may be damaged
Solution Approach 1:
The protection cap serves as an intermediary element between the bolt and the cutting tool. Instead of applying force directly to cut the bolt, the cap can be easily removed or the bolt can be accessed through the cap, eliminating the need for forceful cutting that could damage the substrate.
Solution Approach 2:
The protection cap is designed as a temporary, easily replaceable component. Rather than attempting to remove or cut the permanent bolt fixture, a disposable or reusable cap is used to cover the bolt during periods when it should not be exposed, and can be quickly removed when access is needed.
3Shape
If a protection cap assembly is introduced to cover the bolt, then aesthetics are improved and cutting is avoided, but the device complexity increases
Solution Approach 1:
The protection cap assembly is segmented into distinct functional components including the cap body, gripping shaft with fins, and set screws. This segmentation allows each component to perform its specific function while keeping the overall design simple and modular, making the assembly easy to manufacture and install despite the improved aesthetic functionality.
