Wrist Brace with Adjustable Splint for Motion Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wrist braces often compromise normal motion range and ease due to protection against abnormal motions, and are hindered by issues like added weight, poor fit, cost, and appearance.
Innovation Solution
A wrist brace design featuring a base with outside fastening straps and a semi-rigid or flexible splint, where a third strap is used to adjust the splint's position relative to the wrist for optimal support without restricting normal motion, optionally incorporating an outside stay for additional support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wrist brace provides protection against abnormal motions, then the wrist is protected from injury, but the range and ease of normal motion is reduced
Solution Approach 1:
The wrist brace employs dynamic support through adjustable straps and a removable splint that can be positioned to provide protection during abnormal motions while allowing full range of motion during normal activities. The support structure adapts its rigidity based on the functional requirements of the wrist.
Solution Approach 2:
The brace provides localized support at specific areas of the wrist where abnormal motions occur, while leaving other areas free for normal motion. The splint and straps are positioned to target specific vulnerable zones without restricting overall wrist flexibility.
2Reliability
If a wrist brace provides support and protection, then the wrist is protected from injury, but the weight of the device increases
Solution Approach 1:
The wrist brace utilizes thin, flexible materials for the base structure and straps, providing necessary support while minimizing weight. The splint can be removed entirely when full wrist motion is needed, further reducing the effective weight during normal activities.
Solution Approach 2:
The removable splint and adjustable straps allow the brace to dynamically adjust its weight and support level based on the user's needs, providing maximum protection when required while minimizing weight during normal use.
3Reliability
If a wrist brace provides protection against abnormal motions, then the wrist is protected from injury, but the fit and comfort are reduced
Solution Approach 1:
The adjustable straps and removable splint enable the brace to dynamically adapt to different wrist sizes and shapes, providing a custom fit for each user while maintaining comfort during extended wear.
Solution Approach 2:
The brace is divided into separable components including the base, adjustable straps, and removable splint, allowing each component to be independently adjusted for optimal fit and comfort while maintaining protective function.

AI summary
A wrist brace for use by athletes or others requiring protection and support of the elbow. The wrist brace includes a base and two external straps for fastening the base to the wrist of a person, and a third strap located either on the inside or the outside of the base for pulling a support splint into the wrist when worn.
