Refillable Shaving Head Blade Retention and Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shaver systems require users to discard more than just the blade when replacing it, leading to material waste and pose safety risks due to complex and unwieldy mechanisms for separating the blade from the head.
Innovation Solution
A refillable shaver head with a guard and cover that can move between retaining and releasing positions, allowing for easy blade replacement without discarding the head, using a latch mechanism, spring-loaded pin, and positioning features for secure retention and detachment, along with a blade storage device for safe and efficient blade swapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire head (including cover and guard) is replaced to change the blade, then the blade replacement is simple, but material resources are wasted and the device becomes more complex
Solution Approach 1:
The head is divided into three separable components: the cover, the guard, and the blade. The cover can be detached from the guard to expose the blade for replacement, while the guard and cover can be retained and reused. This segmentation allows users to replace only the blade rather than the entire head assembly, reducing material waste while maintaining ease of operation.
2Loss of substance
If complex mechanisms are used to separate the blade from the head, then the blade can be retained, but the device becomes more complex and user safety is compromised
Solution Approach 1:
The cover is designed to be dynamically movable between a closed position (where it covers and protects the blade) and an open position (where it allows blade access). The hinge connection enables this dynamic movement, allowing the cover to be easily detached and reattached without complex locking mechanisms, thus conserving materials while maintaining simplicity and user safety.
3Loss of substance
If the cover and guard are kept separate for blade replacement, then material waste is reduced, but the ease of operation decreases due to handling small components near cutting edges
Solution Approach 1:
The hinge connection acts as an intermediary mechanism that allows the cover to be temporarily detached from the guard for blade replacement, then easily reattached. This intermediary connection method enables material conservation while maintaining user safety and convenience, as the cover can be quickly secured back to the guard without requiring complex assembly procedures near the cutting edge.

AI summary
A blade storage system for a refillable shaving head including a guard and a cover movable with respect to the guard between a retaining position, in which the cover and guard are able to retain a blade between them and a releasing position. The blade storage system including: a dispensing portion configured to retainably connect the blade to the cover of the head, and a removing portion configured to disconnect the blade from the cover. The removing portion is configured to disconnect the blade from the cover by moving the blade with respect to the cover along a bearing direction, along which the cover is configured to bear on the blade during retention of the blade to the head, and/or the dispensing portion is configured to connect the blade to the cover by moving the blade with respect to the cover opposite to the bearing direction.
