Synchronized Neck Brace Adjustment via Single Linkage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional neck braces lack adjustable mechanisms that allow simultaneous and synchronized adjustment of the neck collar and chin support, leading to potential repeated injuries due to uneven heights.
Innovation Solution
An adjustable neck brace design featuring a sliding engaging groove with a first engaging portion and a single positioning member with a second engaging portion, connected by at least one connecting member, enabling the chin support to be adjusted relative to the neck collar through a single operation, ensuring synchronized height adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two adjusting structures are disposed on two sides of the adjustable brace to allow adjustment of relative positions, then the adaptability is improved, but the device complexity increases and the ease of operation deteriorates because both structures need to be adjusted simultaneously
Solution Approach 1:
The patent combines two separate adjusting structures into a single adjusting structure. The first adjusting structure is integrated with the second adjusting structure such that adjusting one automatically adjusts the other, eliminating the need for simultaneous manual adjustment of both sides while maintaining the adaptability of the neck brace
2Adaptability or versatility
If two adjusting structures are disposed on two sides of the adjustable brace, then the adaptability is improved, but the device complexity increases due to multiple adjusting mechanisms
Solution Approach 1:
The patent merges multiple adjusting mechanisms into a single integrated adjusting structure. The first and second adjusting structures are combined into one mechanism that simultaneously controls both sides of the neck brace, thereby reducing device complexity while preserving full adjustability functionality
3Ease of operation
If a single positioning member is used with a sliding engaging groove, then the ease of operation is improved, but the manufacturing precision requirements increase to ensure proper engagement
Solution Approach 1:
The patent employs a sliding engaging groove mechanism that allows dynamic adjustment through a single positioning member. The groove provides guided movement with built-in engagement features that maintain precise positioning during operation, balancing ease of adjustment with manufacturing feasibility through a mechanically guided path rather than requiring high-precision fixed positions
