Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable end cap systems for support rods are complex and difficult to use, necessitating improvements for simplified construction and functionality.
Innovation Solution
The introduction of spring-biased end caps that include an outer body, inner body, and a helical compression spring, allowing for secure engagement with support surfaces through adjustable tension, facilitated by grooves or threading to retain the spring and maintain alignment of the components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional adjustable end cap systems are used, then the rod assembly can be adjusted to desired length, but the construction and installation process becomes complex and difficult
Solution Approach 1:
The patent combines the mounting plate and the adjustment mechanism into a single integrated end cap assembly. The inner rod with adjustment features is directly received within the outer rod and end cap structure, eliminating the need for separate mounting plates and complex assembly steps. This merging of components simplifies both construction and installation while maintaining adjustability.
Solution Approach 2:
The end cap assembly serves multiple functions simultaneously: it provides structural support, enables length adjustment, and facilitates secure mounting to surfaces. The spring mechanism provides both tensioning force and locking function, while the grooves serve both retention and alignment purposes. This multi-functionality reduces the number of separate components needed.
2Reliability
If spring-biased end caps with multiple components are used, then secure tension-based mounting is achieved, but the number of parts and assembly complexity increases
Solution Approach 1:
The patent employs a nested structure where the inner rod is received within the outer rod, which is in turn received within the end cap. The spring is nested within the end cap structure, and grooves are formed directly in the end cap body. This nesting approach allows multiple functional components to be integrated into a compact assembly that appears as a single unit during installation.
Solution Approach 2:
The spring mechanism automatically tensions and locks the rod assembly in place without requiring additional fasteners or complex assembly procedures. The grooves self-align components during installation, and the spring's elastic properties provide automatic adjustment and securing functionality. This self-service capability reduces the need for multiple separate parts and simplifies assembly.

AI summary
A spring-biased end cap for mounting a rod assembly is provided including an outer body, an inner body, and a spring engaging both the outer body and the inner body to change a position of the inner body relative to the outer body upon compression or expansion of the spring. A rod is received within the outer body and fixed to the inner body. In embodiments, the spring has a first end portion connected to the outer body, a second end portion capable of being connected to the inner body to connect the outer body to the inner body, and an intermediate portion extending within a cavity of the outer body. A rod assembly including the spring-biased end cap and a method of mounting a rod assembly using the spring-biased end cap are also provided.
