Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable razor cartridges made of metal and plastic generate significant plastic waste due to their limited use life before blades dull, posing environmental concerns and user safety risks.
Innovation Solution
A fully metal razor design with customizable blade configurations, allowing for recycling of all components, including blades and spacers, and optional cartridge systems with biodegradable materials for safe disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If disposable razor cartridges with metal blades and plastic housing are used, then convenience and ease of disposal are improved, but plastic waste generation increases significantly
Solution Approach 1:
The patent extracts the blades from the plastic cartridge housing, allowing users to remove and recycle only the metal blades while retaining the reusable handle and cartridge body. This separation enables metal recycling without requiring disposal of the entire plastic cartridge, thus reducing plastic waste while maintaining convenience.
Solution Approach 2:
The patent implements a system where the metal blades are designed for easy removal and recycling, while the cartridge housing and handle are retained for continued use. This selective discarding and recovering approach allows the valuable metal components to be recovered and recycled, while the plastic components remain in service, significantly reducing overall waste.
2Reliability
If blades are made disposable in plastic cartridges, then user safety is improved by allowing easy replacement of dull blades, but environmental harm increases due to non-recyclable plastic waste
Solution Approach 1:
The blades are extracted as separate removable components from the cartridge housing. This allows users to safely replace dull blades without dealing with the entire cartridge, maintaining safety benefits while enabling the housing to be reused and the metal blades to be recycled, thereby reducing environmental harm.
Solution Approach 2:
The patent changes the material parameter of the cartridge housing from disposable plastic to reusable metal or durable materials. This parameter change allows the housing to be reused multiple times, reducing the frequency of disposal and associated environmental harm, while the metal blades maintain their recyclability.
3Ease of manufacture
If traditional disposable razors with fixed blade configurations are used, then manufacturing simplicity is maintained, but user customization and adaptability are limited
Solution Approach 1:
The razor system is segmented into modular components: the handle, cartridge housing, and individual blades. This segmentation allows for standardized manufacturing of each component while enabling users to customize blade configurations by selecting different numbers and types of blades, thus maintaining manufacturing simplicity while increasing adaptability.
Solution Approach 2:
The patent introduces dynamic configurability to the razor system, allowing users to adjust blade numbers and arrangements according to their specific needs. The modular design enables the system to adapt to different user preferences and shaving requirements without complicating the core manufacturing processes through standardized interfaces and components.

AI summary
The invention is for a razor that is made from a solid piece of material, including a handle and razor head. The razor head would be able to accept multiple loose blades separated by a spacer, preferably biodegradable. The loose blades could also distributed in a recyclable housing that clips into the razor head, wherein the blades were able to be removed from the housing. In the case of the loose blades, the blades would be attached to the head using a threaded fastener such as a screw or bolt. The entire razor would be easily disposed of in the owner's recycling bins so as to not make the normal waste of throwing the blades and the plastic housing, which prevents them from being recycled.
