Adjustable Hoop Clamp for Variable Rod Diameter Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hoops for fastening electronic devices on rod bodies are limited in their applicability due to the fixed spacing of fastening holes, leading to poor fastening effects on rod bodies with varying diameters.
Innovation Solution
A hoop design featuring a strap with multiple fastening holes, a strap buckle, a support member, and a driving member, allowing the hoop to be tightly secured onto rod bodies of varying sizes by adjusting the position of the support member using a hand torsion bar or similar driving mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the hoop uses fixed spacing fastening holes on the strap, then the structure is simple and easy to manufacture, but the scope of applicable rod bodies is limited and fastening effect is poor for varying diameters
Solution Approach 1:
The support member is made movable relative to the buckle body through a driving member (such as a hand torsion bar or screw mechanism), allowing the distance between the support member and rod body to be dynamically adjusted. This enables the hoop to adapt to rod bodies of different diameters by moving the support member closer to or farther from the rod body, thereby resolving the contradiction between fixed fastening holes and variable rod body sizes.
Solution Approach 2:
The driving member changes the geometric parameter (distance) between the support member and the rod body. By adjusting this parameter, the hoop can accommodate rod bodies with different cross-sectional sizes even when using fixed-spacing fastening holes, thus improving adaptability without requiring complex adjustable fastening hole positions.
2Reliability
If the support member is positioned close to the rod body, then the fastening effect is strong and sliding is prevented, but friction and wear increase
Solution Approach 1:
A cushioning member (such as an elastic pad or rubber layer) is introduced as an intermediary between the support member and the rod body. This cushioning member reduces direct contact and friction between the metal support member and the rod body surface, thereby decreasing wear while maintaining the compressive force needed to prevent sliding and ensure reliable fastening.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The hoop can be securely fastened to a wide range of rod body sizes, preventing sliding and compressive deformation, while minimizing friction and wear, and ensuring a stable connection.
Implementation Method 1
the driving member is configured to drive the support member to move in a direction close to or away from the buckle body
Implementation Method 2
the driving member drives the support member to move in the direction away from the buckle body to press the rod body, so that the strap is tightly held onto the rod body
Implementation Method 3
the elastic pad is configured to reduce friction and wear between the support member and the rod body
