Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional skincare devices with spring-loaded hinges to facilitate mobility between the shaver head and handle increase complexity and cost, necessitating a simpler and cost-effective solution.
Innovation Solution
A handle design featuring a manipulation portion, a connection portion, and a first flexible portion with deformation cells that allow bending and torsional movement, made from different materials such as ABS-like photopolymer resin and rubber-like photopolymer resin, enabling the connection portion to move relative to the manipulation portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If spring-loaded hinges are used to enable mobility between shaver head and handle, then contact between head and skin is facilitated, but device complexity and cost increase
Solution Approach 1:
The patent applies this principle by incorporating a flexible portion with deformation cells into the handle structure. This flexible portion allows the handle to bend and adapt to skin contours without requiring complex mechanical hinges, thereby maintaining ease of operation while reducing device complexity
Solution Approach 2:
The patent changes the physical parameters of the handle by introducing deformation cells that alter the structural rigidity. These cells enable the handle to transition between rigid and flexible states, allowing skin contact adaptation without complex moving parts
2Ease of operation
If spring-loaded hinges are used to enable mobility between shaver head and handle, then contact between head and skin is facilitated, but cost increases
Solution Approach 1:
The flexible portion with deformation cells is designed to be integrated into the handle as a single piece or minimal assembly, eliminating the need for multiple hinge components, springs, and associated fasteners. This integration significantly reduces manufacturing complexity and cost while maintaining the ability to facilitate skin contact
Solution Approach 2:
The patent merges the functions of the handle structure and the mobility mechanism into a single integrated component. The deformation cells are embedded within the handle body itself, combining structural support and flexible movement capabilities into one element, thereby reducing part count and manufacturing cost
