Razor Shaving Aid Delivery via Rotating Substrate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shaving aid delivery systems in razor heads are inefficient, as they often lead to inconsistent lubrication, premature depletion of shaving aids, and mismatched lifecycles with razor blades, affecting shaving performance and user convenience.
Innovation Solution
A substrate-based shaving aid delivery system within the razor head, featuring a rotatable shaft with a first reel and actuator, allowing for controlled unwinding and rewinding of a substrate with shaving aid, ensuring consistent and adaptable lubrication through a compact and easy-to-manufacture design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional shaving aid delivery systems (gels, creams, lotions) are used in razor heads, then they require auxiliary means (channels, dispensing containers, pumps, rollers) to support application, but this increases device complexity and manufacturing difficulty
Solution Approach 1:
The patent extracts the shaving aid from traditional complex delivery systems (gels, creams, lotions requiring channels, dispensing containers, pumps, rollers) and repositions it as a coating applied directly to the razor head surface. This eliminates the need for auxiliary delivery mechanisms while maintaining shaving aid functionality.
Solution Approach 2:
The patent employs a disposable substrate-based shaving aid delivery system where the substrate with applied shaving aid coating is discarded after use. This simple, single-use approach eliminates complex reusable mechanisms and reduces manufacturing complexity while ensuring consistent shaving aid delivery.
2Reliability
If lubrication strips are attached to razor heads, then they simplify the delivery system, but the shaving aid supply is typically exhausted before the razor blades wear out, reducing reliability
Solution Approach 1:
The patent changes the physical form and application parameters of the shaving aid from traditional strips to a coating applied on a substrate. This allows for more precise control of shaving aid quantity, distribution, and timing, enabling better coordination between shaving aid consumption and blade usage duration.
Solution Approach 2:
The shaving aid is pre-applied as a coating on the substrate before the razor is used. This preliminary preparation ensures consistent shaving aid availability from the first use, and the substrate can be designed to release the shaving aid at the optimal moment during the shaving process.
3Adaptability or versatility
If shaving aid is applied as a coating on the razor head, then it simplifies the delivery system, but it provides no mechanism to extend usage or allow users to determine when to replace the shaving aid, affecting adaptability
Solution Approach 1:
The patent incorporates visual indicators (such as color changes, transparent windows, or visible substrate depletion) that provide feedback to users about the remaining shaving aid supply. This allows users to monitor and determine when to replace the substrate, enhancing adaptability without complicating operation.
Solution Approach 2:
The substrate-based system allows for dynamic adjustment of shaving aid delivery. The substrate can be designed to release shaving aid progressively during use, and users can choose when to replace it based on visual feedback, providing flexibility and adaptability in usage patterns.
