Segmented Wrist Guard with Localized Compression Pads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wrist guards compress the entire wrist area, which can interfere with blood circulation and lead to side effects like hand numbness and swelling, especially when worn for extended periods.
Innovation Solution
A wrist guard design that includes a band body encircling the wrist and a pair of compression pads to specifically compress the radial and ulnar parts of the wrist, allowing the remaining area to remain uncompressed, thus preventing interference with blood circulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wrist guard compresses the entire wrist area to protect the wrist joints, then the wrist protection function is improved, but blood circulation is hindered causing hand numbness and swelling
Solution Approach 1:
The wrist guard divides the compression function into separate segments: compression pads for the radial and ulnar parts, and a non-compressing band body for the dorsal and palmar aspects. This segmentation allows targeted compression where needed while preserving blood circulation pathways.
Solution Approach 2:
The wrist guard applies different mechanical properties to different regions: the compression pads provide firm compression to the radial and ulnar parts for joint stability, while the band body maintains flexibility and non-compression characteristics to allow blood flow through the dorsal and palmar aspects of the wrist.
2Stability of the object's composition
If the wrist guard compresses the entire wrist area to prevent excessive bending, then the wrist stabilization is improved, but hand numbness and swelling occur due to restricted blood flow
Solution Approach 1:
The wrist guard segments the compression function into discrete pads positioned at the radial and ulnar parts, separated from the band body that contacts the dorsal and palmar aspects. This allows stabilization through targeted compression without restricting overall wrist flexibility and blood flow.
Solution Approach 2:
The design applies firm compression locally at the radial and ulnar parts to prevent excessive bending, while the band body maintains a non-compressing, flexible quality that allows natural wrist movement and blood circulation during extended wear.
3Reliability
If compression pads are added to specifically compress radial and ulnar parts, then targeted compression is achieved, but device complexity increases
Solution Approach 1:
The wrist guard uses simple segmented components: a basic band body and separate compression pads. The pads are positioned between the band body layers, creating a straightforward segmented structure that achieves targeted compression without complex mechanisms.
Solution Approach 2:
The compression pads and band body are merged into a single integrated wrist guard unit, where the pads are positioned within the band body structure. This combining approach achieves targeted compression functionality without requiring separate devices or complex assembly mechanisms.

Function Achieved in This Case
The wrist guard effectively prevents excessive wrist bending and alleviates pain while maintaining blood circulation, reducing the risk of side effects like numbness and swelling, and allowing for convenient, long-term use.
Implementation Method 1
a pair of compression pads disposed on opposite portions of the band body worn on the wrist to respectively compress a part of the wrist

AI summary
The present invention relates to a wrist guard and provides a wrist guard that does not pressurize the entire wrist portion but allows for pressurizing only the radius portion and the ulna portion, thereby not only performing a wrist protection function in a stable manner, but also not hindering blood circulation since other portions of the wrist are not pressurized, and thus may be conveniently used since side-effects such as hand numbness or hand swelling do not occur even when wearing same for a long period, and the position and thickness of a pressurizing pad for pressurizing the radius portion and the ulna portion of the wrist may be adjusted according to the needs of a user, and thus the wrist guard may be more conveniently used since same may be altered into an optimal state according to physical conditions of the user or environmental conditions.
