Transparent Curable Adhesive Blade Guard for Razor Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing razor blade test samples pose a risk of injury due to exposed cutting edges, and conventional protective caps obscure the product, making them difficult to display effectively.
Innovation Solution
An optically transparent, hardening adhesive is applied in one or more layers over the razor blades and/or the razor blade holder to completely embed the cutting edges, providing a strong and visible blade guard that prevents injuries and enhances presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a protective cap is attached to the razor blade holder, then the cutting edges are protected, but the product appearance is obscured and it is difficult to display
Solution Approach 1:
The harmful cutting edges are extracted from direct exposure by embedding them within the adhesive matrix. The adhesive encapsulates the cutting edges while maintaining optical transparency, effectively separating the protective function from the visual display function.
Solution Approach 2:
An optically transparent adhesive serves as an intermediary medium between the cutting edges and the external environment. This mediator provides protection while allowing light to pass through, enabling both safety and product visibility simultaneously.
2Object-affected harmful factors
If a protective cap is firmly connected to the razor blade holder, then protection is ensured, but the structure becomes complex and material costs increase
Solution Approach 1:
The protective function is merged with the adhesive bonding function. The same adhesive that secures the blade to the holder also provides protection by embedding the cutting edges, eliminating the need for separate protective components and simplifying the overall structure.
Solution Approach 2:
The adhesive performs multiple functions simultaneously: it bonds the blade to the holder, protects the cutting edges by embedding them, and maintains optical transparency for display purposes. This multi-functionality reduces the number of components needed.
3Object-affected harmful factors
If the cutting edges are completely embedded in adhesive, then protection is maximized, but the adhesive must be optically transparent to maintain visibility
Solution Approach 1:
The adhesive is applied with specific local properties: it is optically transparent in the regions where visibility is needed, while providing complete embedding and protection of the cutting edges. The adhesive's optical and mechanical properties are optimized for their specific functions.
