Dual-Rod Positioning Seat for Stable Gap-Free Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dual rod positioning structures for larger rods, which involve a spring and protrusion mechanism, suffer from assembly complexity and positioning instability due to gaps between rods, making them difficult to align and connect securely.
Innovation Solution
A dual rod positioning structure featuring positioning holes on the rods and a positioning seat with a spring, positioning pin, and button mechanism, allowing for precise alignment and secure engagement of rods through a tilting mechanism that utilizes the spring's elastic force for stable connection and disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spring and protrusion positioning structure is used to connect two single rods, then the positioning operation is simple, but the positioning stability deteriorates due to gaps between the rods
Solution Approach 1:
The positioning structure is segmented into distinct functional components: positioning holes in the rod bodies and a separate positioning seat with engagement features. This segmentation allows each component to be optimized independently while working together to eliminate gaps and improve positioning stability without complicating the operation.
2Ease of manufacture
If a spring and protrusion positioning structure is used to facilitate assembly, then the assembly is easier, but the structure complexity increases due to the need for spring connection and positioning structure placement
Solution Approach 1:
The positioning seat integrates multiple functions into a single component: it contains the positioning element, spring, and engagement features all in one integrated structure. This merging eliminates the need for separate spring connections and positioning structure placements, reducing assembly steps while maintaining ease of assembly and reducing overall structural complexity.
Solution Approach 2:
The positioning seat is designed to self-position and self-lock into the positioning holes without requiring external alignment tools or complex assembly procedures. The spring automatically provides the necessary force for engagement, and the positioning elements automatically align with the positioning holes, making the assembly process simple while keeping the structure compact and straightforward.

AI summary
A dual rod positioning structure, for connecting and fixing two single rods sleeved on or inserted into one another, includes positioning holes respectively located on rod bodies of the two single rods and a positioning seat capable of being engagedly fixed to the positioning holes and sleeved on the single rods. The positioning holes are arranged on two adjacent sidewalls of the single rods. Inserted into the positioning seat are a positioning element selectively engaged in the positioning holes, a spring, a positioning pin and an outward protruding button. The positioning structure overall is structurally simple, convenient to assemble, and stable in terms of positioning.
