Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual shaving razors face issues with limited blade options, alignment difficulties, lack of pivoting mechanisms, skin irritation, high replacement costs, and excessive waste due to disposable components in both classic safety and cartridge razors.
Innovation Solution
A re-configurable razor with a customizable head that allows users to adjust the number and spacing of blades, featuring a pivot mechanism, adjustable spring, and a magnetized handle for easy blade alignment and reduced waste, along with a built-in lubrication system for improved comfort and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If classic safety razors use one or two blades to reduce cost, then manufacturing cost is reduced, but shaving performance and user comfort deteriorate
Solution Approach 1:
The razor head is segmented into multiple blade slots (typically 3-5 blades) arranged in parallel, allowing each blade to contribute to the shaving process independently. This segmentation enables better hair cutting performance while maintaining cost-effectiveness through modular blade design
Solution Approach 2:
The razor head incorporates multiple functional elements: cutting blades, lubricating strips, and cushioning mechanisms all in one universal head assembly. This multi-functionality delivers cartridge-razor-level performance without the high replacement costs, as the entire head can be replaced affordably
2Device complexity
If classic safety razors lack a pivoting mechanism to simplify design, then device complexity is reduced, but ease of operation and safety deteriorate
Solution Approach 1:
The razor head incorporates a pivoting mechanism that allows dynamic adjustment of the blade angle relative to the handle. This enables the head to adapt to contours of the face and maintain optimal shaving angle automatically, significantly improving ease of operation and safety
Solution Approach 2:
The pivoting mechanism is designed to self-adjust during shaving based on applied pressure and facial contours, reducing the skill level required. The mechanism automatically maintains the correct blade-to-skin angle without requiring user expertise
3Device complexity
If classic safety razors require manual blade loading to reduce components, then device complexity is reduced, but safety deteriorates due to injury risk
Solution Approach 1:
A protective guard or cover acts as an intermediary between the user and the sharp blades during loading and handling. This intermediary component allows users to safely load and store blades without direct contact, significantly reducing injury risk while maintaining simple overall design
4Device complexity
If classic safety razors lack built-in lubrication to simplify design, then device complexity is reduced, but comfort and skin protection deteriorate
Solution Approach 1:
The lubricating strip is merged directly into the razor head assembly, combining the cutting function and lubrication function in a single integrated component. This eliminates the need for separate lubrication application steps, improving comfort and reducing skin irritation without significantly increasing complexity

AI summary
A razor including a head and a handle attached to the head via a pivot mechanism. An adjustable spring is used to orient the head. The head includes a top member, a bottom member, and one or more pins to retain a blade stack between the top member and the bottom member, the blade stack to comprise at least one razor blade and at least one spacer. The head also includes at least one removable fastener to enable the user to fasten the top member and the bottom member around the blade stack. The handle may be made of multiple segments with a common connection type making it reconfigurable by the user. The head may have channels to allow a fluid, gel or product from a cavity in the handle to the surface of the head. The handle may have a magnet at the end or in the last segment.
