Solution Overview

Problem

Existing manual razors with temperature-changing functions increase component count, cost, and volume due to separate temperature-changing components near the blades, occupying more space.

Innovation Solution

A manual razor design with a handle and blade rest connected via a heat transfer structure, allowing the handle to heat or cool the blade through direct heat conduction, reducing the number of components and enhancing shaving experience by adjusting blade temperature for comfort and effectiveness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate temperature-changing components are added near the blades, then temperature control function is achieved, but device complexity and occupied space increase

Engineering Contradiction:

Improvetemperature control functionVSAvoidcomponent count

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the temperature control function directly into the handle assembly by integrating heating or refrigeration structures within the handle. This eliminates the need for separate temperature-changing components near the blades, thereby reducing device complexity and occupied space while maintaining the temperature control function. The handle structure is redesigned to incorporate thermal management capabilities, combining multiple functions into a single integrated component.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If separate temperature-changing components are added near the blades, then temperature control function is achieved, but manufacturing cost increases

Engineering Contradiction:

Improvetemperature control functionVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By integrating the temperature control function into the existing handle structure rather than adding separate components, the patent reduces the total number of parts that need to be manufactured and assembled. This integration approach simplifies the manufacturing process, reduces component procurement costs, and lowers overall production complexity, thereby reducing manufacturing cost while maintaining the temperature control function.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If separate temperature-changing components are added near the blades, then temperature control function is achieved, but overall volume increases

Engineering Contradiction:

Improvetemperature control functionVSAvoidoccupied space

Core Design Contradiction:

Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The patent incorporates the temperature control function within the existing handle volume by designing integrated heating or refrigeration structures that utilize the handle's internal space. This eliminates the need for additional space near the blades, thereby maintaining a compact overall design and reducing occupied space while achieving the temperature control function.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Provided is a manual razor having a temperature-changing function. The handle is provided with the heat transfer structure having both heating and refrigeration functions, or the refrigeration structure only having a refrigeration function, or the heating structure only having a heating function, and the heat transfer structure, the refrigeration structure or the heating structure is directly connected to the blade in a heat conduction mode, so that the temperature of the blade for shaving is changed along with the change of the temperature of the heat transfer structure, the refrigeration structure or the heating structure. Moreover, the razor has few structural components and is low in cost, compact in overall structure, and small in occupied space.
