Solution Overview

Problem

Existing shaving product kits limit user flexibility by bundling specific razor handles with cartridges, restricting the ability to mix and match different operative effect handles with various cartridges, which hampers user selection and customization.

Innovation Solution

A method where razor handles and cartridges are displayed digitally or in print, providing information only on compatible handles and cartridges, allowing users to select and connect different handles and cartridges based on their desired operative effects, with each handle and cartridge having distinct features and functionalities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If razor handles and cartridges are bundled together in kits within single disposable blister packages, then consumers receive a ready-to-shave solution with both components, but user flexibility and selection options are limited

Engineering Contradiction:
Improveready-to-shave convenienceVSAvoiduser selection flexibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The invention separates razor handles and cartridges into distinct packaging units. Razor handles are packaged in first blister packages while cartridges are packaged in second blister packages, allowing them to be sold and selected independently rather than being forced into bundled kits. This segmentation enables users to choose specific handles and cartridges separately while maintaining the convenience of pre-packaged, ready-to-use components.

Inventive Principle:
Principle #1Segmentation

2Loss of information

If information on razor handles is provided together with information on attached cartridges, then complete product information is available, but users cannot independently select handles with different operative effects

Engineering Contradiction:
Improveproduct information completenessVSAvoidhandle selection independence
Core Design Contradiction:
Loss of informationVSAdaptability or versatility

Solution Approach 1:

The information presentation is segmented into separate components: first information about razor handles is provided independently on or with first blister packages containing handles, and second information about cartridges is provided independently on or with second blister packages containing cartridges. This allows users to review handle information, select a desired handle based on operative effects, and then separately select compatible cartridges without being constrained by pre-bundled kit information.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If multiple razor handles with different operative effects are made compatible with one or more cartridges, then user customization options increase, but the complexity of product compatibility information increases

Engineering Contradiction:
Improvehandle-cartridge compatibility optionsVSAvoidproduct information complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention uses the blister package structure as an intermediary organization system. First blister packages contain and present razor handle information, while second blister packages contain and present cartridge information. This intermediary packaging structure naturally organizes the compatibility information, making it easier for users to understand which cartridges work with which handles without being overwhelmed by complex technical specifications.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A method of selecting from a system of shaving products 22, 32. The method includes providing information only on a first razor handle 23 connectable in use with a razor blade cartridge 42. The first razor handle is configured to provide a first operative effect. The method includes providing information only on a second razor handle 33 connectable in use with the razor blade cartridge. The second razor handle is configured to provide a second operative effect, different from the first operative effect. The method includes selecting one of the first razor handle or the second razor handle.
