Hallux Valgus Corrector With Knob-Locking Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing hallux valgus correctors are inconvenient to adjust due to the need for tightening knobs to be repeatedly loosened and retightened for adjustments.
Innovation Solution
A hallux valgus corrector design featuring a metatarsal support part, hallux support part, and sole wearable part, with a corrective and adjusting component that includes a second live shaft, knob, positioning part, and elastic clamping pieces, allowing for easy angle adjustments by rotating the knob, which locks into place via an internal gear mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rotating button is used to tighten ropes for angle adjustment, then the adjustment can be tightened, but it becomes inconvenient to loosen and readjust
Solution Approach 1:
The correction component transitions from a static tightening mechanism to a dynamic system with bidirectional adjustment capability. The elastic clamping piece enables the mechanism to switch between locked and adjustable states, allowing users to easily loosen and readjust the angle without complex operations.
Solution Approach 2:
The elastic clamping piece automatically engages with the gear structure to maintain the adjusted position without requiring additional locking actions. The system self-locks after adjustment, eliminating the need for separate tightening and loosening operations while maintaining fixation stability.
2Stability of the object's composition
If the corrective and adjusting component is fixed tightly, then the hallux support part is stable, but it cannot be readjusted easily
Solution Approach 1:
The adjustment mechanism transforms the support structure from a fixed-state system to a dynamically adjustable system. The elastic clamping piece allows the component to transition between stable locked positions and adjustable states, providing both stability during use and flexibility during adjustment.
Solution Approach 2:
The mechanism enables changes in the angular parameter of the hallux support part while maintaining structural stability. By modifying the clamping force and engagement state of the elastic clamping piece, the system allows discrete angular adjustments while preserving stability at each adjusted position.
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
Enables simple and convenient adjustment of tightness by rotating the knob, allowing for stable and stable fixation of the hallux and metatarsal support parts, facilitating easy readjustment without the need for repeated loosening and tightening.
Implementation Method 1
An elastic clamping piece is arranged in the knob to elastically lock with the internal gear
Implementation Method 2
other end of the rope is wrapped around the live shaft

AI summary
A hallux valgus corrector comprises a metatarsal support part, a hallux support part, a hallux wearable part and a sole wearable part. A corrective and adjusting component is arranged on the metatarsal support part for adjusting an angle of the hallux support part. The corrective and adjusting component comprises a second live shaft, a knob, a positioning part and a rope. The sole wearable part is wore on the sole, and the hallux support part is wore on the hallux. Rotate the knob, and the second live shaft rotates and the rope wraps around the second live shaft, thereby pulling the hallux support part to rotate for angle adjustment. Rotate the knob clockwisely or counterclockwisely to adjust the tightness.
