Solution Overview

Problem

Current razors lack haptic, visual, acoustic, or tactile feedback, making the shaving experience dull and uneventful, failing to leverage the potential for enhanced user experience through sensory stimulation.

Innovation Solution

A razor head with resilient elements connected to cutting members that transduce vibrations into electrical signals, which are then converted into mechanical feedback, such as vibrations or sound, using a shaving razor assembly with electronic circuitry and feedback generators, enhancing the user experience through sensory feedback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If resilient elements are added to transduce vibrations into electrical signals, then user sensory feedback is improved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent replaces the traditional purely mechanical razor system with an electromechanical system that incorporates resilient elements capable of transducing mechanical vibrations into electrical signals. This substitution enables sensory feedback functionality while maintaining the core mechanical cutting function, resolving the contradiction between adding feedback capabilities and increasing device complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The resilient elements serve as intermediary components between the mechanical cutting members and the electrical signal processing system. These intermediaries transduce vibrations from the cutting members into electrical signals that can be processed and fed back to the user, enabling sensory feedback without directly complicating the mechanical cutting mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If vibration transduction components are integrated into the razor head, then user experience is enhanced, but manufacturing complexity increases

Engineering Contradiction:
Improveuser experienceVSAvoidmanufacturing complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The resilient elements are designed to perform multiple functions: they provide mechanical support for the cutting members, enable vibration transduction, and facilitate sensory feedback. This multi-functionality reduces the need for separate components, thereby enhancing user experience while managing manufacturing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the vibration transduction functionality with the existing razor head structure by integrating resilient elements that serve both mechanical and sensing purposes. This consolidation reduces the number of separate manufacturing processes required compared to adding entirely separate transduction components.

Inventive Principle:
Principle #5Merging (Combining)
