Disposable Razor Bracket With Manual Control Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current disposable razors lack control and pressure regulation, leading to reduced shave quality and increased irritation due to their long stick design with a fixed blade head.
Innovation Solution
A razor blade head with a bracket and manual control element allows users to apply pressure from the side, enabling improved control and accuracy through a configuration that supports the application of force via the bracket, which is connected to the razor blade element, and features an opening for water flow to prevent clogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a long stick design with a fixed blade head is used, then the razor structure is simple and easy to manufacture, but the user has limited control and ability to regulate pressure on the blade head
Solution Approach 1:
The razor head is segmented into distinct functional components: a blade element, a bracket structure, and a manual control element. This segmentation allows each component to perform its specific function while maintaining overall simplicity. The bracket acts as an intermediary structure that connects the blade to the control mechanism, enabling pressure regulation without complicating the overall design.
Solution Approach 2:
The bracket serves as an intermediary element between the manual control element and the razor blade. It transfers and regulates the force applied by the user's fingers on the control element to the blade element, providing mechanical advantage and precise pressure control. This intermediary structure resolves the contradiction by enabling fine control without requiring complex mechanisms.
2Manufacturing precision
If pressure cannot be regulated on the blade head, then the razor structure remains simple, but the shave quality and accuracy are reduced
Solution Approach 1:
The manual control element enables the user to directly control the pressure applied to the blade through intuitive finger manipulation. The design allows users to self-regulate pressure without requiring complex automated mechanisms or additional control systems. The bracket's mechanical design naturally translates finger pressure into precise blade pressure, making the system self-regulating through user input.
3Productivity
If the bracket is solid without openings, then it provides structural strength, but cut hair can clog and reduce shaving effectiveness
Solution Approach 1:
The bracket is designed with localized openings in specific regions where cut hair accumulation would occur, while maintaining solid structural sections where strength is required. This local modification allows the bracket to perform dual functions: providing structural support where needed and enabling hair egress where appropriate. The selective placement of openings resolves the contradiction between strength and productivity.
