Liquid Dispensing Razor With Integrated Bottle Locking Tab
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid dispensing shaving razors require multiple products and steps, leading to inconvenience, messiness, and extended shaving experiences, as they lack integrated functionality for securely holding the bottle and efficiently delivering liquids.
Innovation Solution
A liquid dispensing shaving razor design featuring a handle body with a mounted shaving razor cartridge and a personal care bottle in fluid communication, incorporating a locking tab for secure attachment and a delaminating bottle with an air gap for efficient liquid delivery, manufactured using injection molding and blow molding for enhanced design and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional liquid dispensing shaving razor uses a hollowed-out handle or aerosol can, then liquid storage is achieved, but the bottle security and liquid delivery functionality are insufficient
Solution Approach 1:
The personal care bottle is separated from the handle body, allowing the bottle to be independently designed with integrated locking and gripping features. The locking tab on the bottle engages with the handle opening, providing secure attachment without requiring complex handle mechanisms. This segmentation allows each component to be optimized for its specific function.
Solution Approach 2:
The personal care bottle is positioned within the handle body structure, with the bottle's locking tab nested within the handle opening. The gripping sleeve of the bottle is received by the handle body, creating a nested arrangement that provides secure mounting while maintaining simplicity in both components.
2Reliability
If multiple shaving products and steps are used, then adequate skin preparation is achieved, but the shaving process becomes inconvenient and time-consuming
Solution Approach 1:
The shaving razor cartridge and personal care bottle are combined into a single integrated razor assembly. The bottle is mounted to the handle body and delivers liquid directly to the cartridge, merging the liquid storage and delivery functions with the shaving function. This eliminates the need for separate skin preparation products and steps, reducing both time and complexity.
Solution Approach 2:
The integrated razor assembly performs multiple functions: the personal care bottle stores and delivers liquid shaving aids, the cartridge provides cutting edges, and the assembly as a whole enables both skin preparation and shaving in one device. This multi-functionality eliminates the need for multiple separate products and application steps.
3Reliability
If a delaminating bag inside a bottle is used for liquid delivery, then liquid dispensing is achieved, but manufacturing design flexibility is limited
Solution Approach 1:
The bottle is manufactured using blow molding processes that allow for various design parameters to be changed, including the inclusion of an air gap between the delaminating bag and bottle wall. This parameter change enables efficient liquid delivery while maintaining manufacturing feasibility and design flexibility.
Solution Approach 2:
The air gap is created in specific locations within the bottle structure, particularly in the distal portion, to facilitate delaminating bag evacuation. This localized quality change allows the delaminating mechanism to function effectively without requiring complete redesign of the entire bottle structure, maintaining ease of manufacture.

AI summary
A liquid dispensing shaving razor with a handle body defining an opening. A shaving razor cartridge is mounted to a first end of the handle body. A personal care bottle is mounted to a distal end of the handle body and in fluid communication with the shaving razor cartridge. The personal care bottle has a locking tab removably positioned within the opening of the handle body securing the personal care bottle to the handle body.
