Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for applying threads to multiple posts projecting from a larger component surface are time-consuming and costly, making it desirable to have a cost-effective and easily produced system for providing a threaded interface on a molded post.
Innovation Solution
A clamp-on-post fastener system comprising a base section and a sleeve section with radially inwardly projecting tooth members and threads, which securely engage a post by clamping onto it, providing a threaded interface without the need for direct machining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If threads are machined directly on multiple posts projecting from a component surface, then a threaded interface is provided, but the manufacturing process becomes time-consuming and costly
Solution Approach 1:
The invention separates the threading operation from the post itself by using a distinct fastener component that attaches to the post. The fastener includes a body with internal threads and a clamping mechanism that secures to the post, eliminating the need to machine threads directly on multiple posts while providing the same threaded interface functionality
Solution Approach 2:
The fastener acts as an intermediary component between the post and the threaded fastening element. Instead of machining threads on the post, the fastener provides a clamping interface that engages the post and a threaded interface that receives bolts or screws, serving as a mediator that eliminates direct machining requirements
2Reliability
If threads are machined directly on posts, then a permanent threaded interface is created, but the process requires significant time and equipment investment
Solution Approach 1:
The fastener is pre-formed with internal threads and clamping features during molding, eliminating the need for subsequent machining operations. This preliminary preparation of the fastening interface allows for quick attachment to posts without time-consuming machining while maintaining reliable threaded engagement
Solution Approach 2:
The fastener is made from molded material that provides sufficient durability for the application without requiring permanent machining. The fastener can be easily replaced if needed, and its molded construction provides reliable engagement without the time investment of machining permanent threads

AI summary
A clamp-on-post fastener includes a base section and a sleeve section including a first end connected with the base section, a second end, and an intermediate portion defining a center axis extending between the first end and the second end. The sleeve section includes an outer surface, a central passage having an inner surface, and a plurality of tooth members that project radially inwardly from the inner surface. The clamp-on-post fastener includes a slot extending through the base section and the sleeve section substantially parallel to the center axis forming a first fastener portion and a second fastener portion that are configured to be brought together to engage a substrate.
