Hand Fixation Band Pivot Structure With Nested Damping Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand fixation bands experience deformation and functional decline due to friction, leading to a compromised pivot structure and appearance over time.
Innovation Solution
A hand fixation band design featuring a fastening band, sliding arm, and damping element with a stabilizing fixing assembly, where the damping element is accommodated within a protruding rib to prevent deformation and maintain structural integrity during repeated pivot rotations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the damping element is assembled between the fastening band and the sliding arm to form a pivot structure, then the pivot structure is initially stable, but after repeated pivoting the damping element deforms and is exposed outside due to friction, affecting appearance and function
Solution Approach 1:
The damping element is nested within the accommodating space formed by the first protruding rib and the locating hole, with the peripheral wall of the locating hole surrounding the damping element. This nesting structure prevents the damping element from deforming and exposing outward during repeated pivoting operations, while maintaining the pivot structure's stability and functionality.
2Stability of the object's composition
If the damping element is constrained within the accommodating space surrounded by the first protruding rib, then the damping element remains stable during pivoting, but the pivot structure's rotational freedom may be limited
Solution Approach 1:
The peripheral wall of the locating hole provides localized constraint only at the boundaries, while the accommodating space within allows free movement of the damping element during pivoting. This local quality approach ensures the damping element remains stable and contained without restricting the overall rotational freedom of the pivot structure.
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 design ensures the hand fixation band maintains normal function and appearance over long-term use by preventing damping element deformation and shifting, while allowing for stable and adjustable pivot rotations.
Implementation Method 1
after the pivot structure of the conventional hand fixation band pivots for many times, the damping element will be deformed to be exposed outside on account of an friction affection

AI summary
A hand fixation band includes a fastening band, a sliding arm and a damping element. The fastening band has a main portion, and a connecting portion protruded outward from one end of the main portion. The connecting portion protrudes downward to form a first protruding rib. An inside of the first protruding rib has an accommodating space. The sliding arm is connected with the fastening band. A top surface of one end of the sliding arm has a buckling slot. The buckling slot is corresponding to and buckled with the first protruding rib. One end of the sliding arm opens a locating hole. A top surface of a peripheral wall of the locating hole surrounded by the buckling slot is defined as an accommodating surface. The damping element is disposed on the accommodating surface and is accommodated in the accommodating space.
