Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing body hair trimmers and shavers face issues due to a lack of elasticity in moving blades, leading to rapid wear and complex, non-compact shaver head structures.
Innovation Solution
A shaver featuring a shaver head with a double-layer elastic structure, comprising first and second elastic parts arranged between different components of the shaver head, providing stable elastic force and ensuring balanced force distribution between blades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single elastic structure is used to support multiple moving blades, then the shaver head structure becomes more compact, but the elastic force distribution and working stability deteriorate
Solution Approach 1:
The single elastic structure is divided into multiple independent elastic parts (first elastic part and second elastic part), with each elastic part dedicated to supporting specific moving blades. This segmentation ensures that each moving blade receives appropriate elastic force independently, improving working stability while maintaining a compact overall structure through organized arrangement of the segmented elastic components.
2Device complexity
If moving blades lack elasticity, then the shaver head structure is simpler, but the moving blades wear rapidly and shaving efficiency decreases
Solution Approach 1:
Elasticity is introduced as a key parameter to the moving blades through the elastic parts, transforming them from rigid non-elastic components to flexible elastic components. This parameter change enables the moving blades to adapt to skin contours and maintain optimal cutting pressure, significantly improving shaving efficiency while the modular elastic structure keeps the overall device complexity manageable.
3Productivity
If moving blades make direct contact with skin, then the cutting action is more effective, but the risk of skin injuries increases
Solution Approach 1:
The moving blades are designed with elastic properties, allowing them to function as flexible cutting elements that conform to skin contours. This flexibility enables effective cutting while reducing the risk of skin injuries by allowing the blades to adapt to the skin surface rather than forcing rigid contact, creating a safer cutting action that maintains effectiveness.
