Elastomeric Ring Grip for Shaver Handle Ergonomics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld devices, such as razors and toothbrushes, have rigid handles that lack flexibility and ergonomics, failing to provide a comfortable and responsive grip, especially when used in wet or soapy environments.
Innovation Solution
A handheld device design featuring a handle with a docking member and a gripping portion that retains an elastomeric substrate with overlapping rings, allowing for a flexible and adaptive grip, enabling enhanced control and comfort through dynamic resistance and customizable surface treatments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid handles are used in handheld devices, then structural strength and stability are improved, but flexibility and ergonomic comfort deteriorate
Solution Approach 1:
The handle is divided into two distinct segments: a rigid core structure providing structural strength, and a flexible elastomeric substrate layer providing ergonomic comfort. This segmentation allows each part to fulfill its specific function without compromise.
Solution Approach 2:
The handle employs a composite structure combining rigid materials (providing strength and stability) with flexible elastomeric materials (providing comfort and adaptability). This composite approach resolves the contradiction by integrating materials with complementary properties.
2Ease of operation
If external grip material is added to rigid handles, then gripping comfort is improved, but the handle remains rigid and elongated
Solution Approach 1:
The elastomeric substrate acts as a flexible shell that conforms to the user's hand, replacing the traditional rigid elongated shape with a form that adapts to ergonomic requirements while maintaining structural integrity through the underlying rigid core.
3Length of moving object
If the handle is made shorter and more portable, then compactness is improved, but control responsiveness may deteriorate
Solution Approach 1:
The elastomeric substrate changes the mechanical parameters of the handle by introducing flexibility and compliance, allowing a shorter handle length to maintain control responsiveness through adaptive deformation rather than rigid leverage.
