Floatably Secured Shaving Blade Member for Enhanced Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wet shaving razors with multiple blades and increased guard areas make it difficult for users to achieve a precise shave due to obstructed visibility of the skin surface, and the clips used to secure blades further hinder visibility and shaving efficiency.
Innovation Solution
A shaving blade unit with a floatably secured cartridge design, featuring a housing with a resilient member that provides a forward biasing force to maintain contact between the shaving blade and the cartridge side wall, eliminating the need for clips and enhancing skin contact area visibility during shaving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clips are used to secure shaving blades to the cartridge housing, then the blades are kept secured to the razor cartridge, but the clips block the view of certain portions of skin surface to be shaved
Solution Approach 1:
The patent removes the clips entirely from the cartridge design. Instead of using clips to secure the shaving blade, the blade is held in place by its own structural features (shoulders at each end that rest along the side walls of the housing) and the resilient member provides forward biasing force. This extraction of the clip component eliminates the visibility obstruction while maintaining blade security through alternative mechanical means.
2Manufacturing precision
If multiple blades are incorporated into wet shaving razors, then users are provided with a closer shave, but it becomes more difficult to see the skin surface being shaved
Solution Approach 1:
By removing the clips that traditionally secured multiple blades in the cartridge, the patent eliminates the visual obstruction caused by these securing components. The multiple blades remain in place through the resilient member's biasing force and the blade shoulders resting on the housing side walls, allowing users to see the skin surface clearly while still benefiting from multiple blades for a closer shave.
3Ease of operation
If increased guard area is provided in razors, then shaving comfort is improved, but it makes it more difficult to achieve a precise shave due to obstructed visibility
Solution Approach 1:
The patent eliminates clips from the cartridge design, removing the visual obstruction that previously hindered shaving precision. The increased guard area is maintained for user comfort, and the blades are secured without clips through the resilient member and shoulder-side wall contact mechanism, allowing users to see the skin surface clearly and achieve precise shaves while retaining the comfort benefits of the larger guard area.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design allows for improved visibility and shaving precision by maintaining contact between the shaving blade and skin surface without clips, ensuring a closer and more comfortable shave while reducing manufacturing complexity and costs.
Implementation Method 1
a resilient member disposed rearward of said shaving blade member and that is secured by a shaving blade member retainer; and wherein said resilient member provides a forward biasing force to said shaving blade member

AI summary
A shaving blade unit comprising a shaving cartridge having a floatably secured shaving blade member wherein said cartridge comprises: a) a housing with a front wall, a rear wall, and opposing side walls extending between said front and rear walls; b) said shaving blade member having opposing ends with a shoulder at each end and wherein said shoulder rests along said side wall and wherein a cutting edge of said shaving blade member is facing a front surface of said housing; c) a resilient member disposed rearward of said shaving blade member and that is secured by a shaving blade member retainer; and wherein said resilient member provides a forward biasing force to said shaving blade member such that said contact between said shoulder and said side wall is at least maintained when said unit is removed from a skin surface during shaving.
