Crutch Grip Retaining Clip Segmentation for Quick Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional crutch grips are cumbersome to adjust and replace, requiring disassembly of the crutch, which is time-consuming and can compromise the reliability of the crutch.
Innovation Solution
A crutch grip design featuring partially annular receivers and retaining clips made from pliable materials that allow easy attachment and detachment from crutch posts without disassembling the crutch, enabling adjustable and replaceable grips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional crutch grips are used with fixed attachment, then the crutch structure is simple and reliable, but the grip adjustment and replacement becomes time-consuming and complex
Solution Approach 1:
The attachment mechanism is segmented into separate components: a grip assembly with partially annular receivers and a retaining clip system. This allows the grip to be independently adjusted and replaced without affecting the entire crutch structure, resolving the contradiction by making adjustment easy while keeping the overall device simple.
Solution Approach 2:
The retaining clip is extracted as a separate removable component from the grip assembly. This allows the grip to be easily detached and reattached by simply removing or inserting the clip, enabling quick adjustment without complex disassembly while maintaining structural simplicity.
2Ease of repair
If traditional rigid attachment methods are used, then the structure is strong and reliable, but the grip cannot be easily removed or replaced
Solution Approach 1:
The attachment system transitions from a fixed rigid connection to a dynamic removable connection using retaining clips. The clips can be easily inserted and removed, allowing the grip to be replaced when worn or damaged, while the engagement between the clip and receivers provides reliable attachment during use.
Solution Approach 2:
The material properties of the retaining clip are changed to be pliable yet strong, allowing it to flex during installation and removal while maintaining secure engagement with the receivers. This parameter change enables easy replacement while ensuring reliable attachment.
3Ease of operation
If the grip is made fully removable, then replacement becomes easy, but the attachment reliability and structural integrity may be compromised
Solution Approach 1:
The retaining clip is made from composite or pliable material that combines flexibility for easy installation with sufficient strength for reliable attachment. This material property combination allows the grip to be easily removed and reattached while maintaining attachment strength and structural integrity during use.

AI summary
A crutch grip (100) includes a grip (101) disposed between a first grip end (102) and a second grip end (103). The first grip end and the second grip end can define a partially annular receiver for a crutch post (106,107). One or more retaining clips (108,109) can include a base member (408,409), a first, curved, cantilevered leg (410,411), and a second, curved, cantilevered leg (412,413). The retaining clips can removably engage an outer surface (202,203) of the first grip end or the second grip end such that an annular clasp (602,603) is defined between the first grip end or the second grip end and the retaining clips.
