Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual cleaning and disinfecting is performed, then the blade assembly can be cleaned, but the process is time-consuming and tedious

Engineering Contradiction:
Improvecleaning thoroughnessVSAvoidcleaning time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The cleaning apparatus enables the blade assembly to be cleaned automatically without manual intervention. The system uses self-contained cleaning members that move autonomously to contact and clean the blade assembly surfaces, eliminating the need for manual brushing and disinfectant application while ensuring thorough cleaning.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical cleaning actions with an automated mechanical system. The cleaning members are driven by a motor to automatically contact and clean the blade assembly, substituting the manual mechanical process with an automated mechanical system that reduces time and labor while maintaining cleaning effectiveness.

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

2Productivity

If manual cleaning is performed quickly to serve more clients, then productivity increases, but cleaning and disinfection is done improperly or neglected

Engineering Contradiction:
Improveclient service speedVSAvoiddisinfection quality
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The automated cleaning system performs complete cleaning and disinfection cycles without requiring manual intervention, ensuring that proper cleaning procedures are always followed regardless of client volume. The system self-regulates the cleaning process to maintain high disinfection quality while freeing up the barber to serve more clients.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The cleaning members continuously move to contact all surfaces of the blade assembly, ensuring complete coverage throughout the cleaning cycle. This continuous action ensures that no area is missed, maintaining high disinfection quality even when the system is used frequently between client appointments.

Inventive Principle:
Principle #20Continuity of useful action

3Reliability

If thorough manual cleaning is performed on both sides of the blade assembly, then disinfection quality improves, but the process becomes even more time-consuming

Engineering Contradiction:
Improvedisinfection completenessVSAvoidcleaning duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The automated system performs thorough cleaning of both sides of the blade assembly simultaneously without requiring the barber to manually flip or reposition the blade. The cleaning members are positioned to contact opposing surfaces, enabling complete disinfection of all blade surfaces in a single automated cycle that is faster than manual methods.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent introduces spatial arrangement of cleaning members on opposite sides of the blade assembly, allowing simultaneous cleaning of multiple surfaces. This dimensional arrangement enables the system to clean both sides of the blade concurrently, achieving complete disinfection without doubling the cleaning time required for sequential manual cleaning.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Productivity

If automated cleaning apparatus is introduced, then cleaning speed and thoroughness improve, but device complexity increases

Engineering Contradiction:
Improvecleaning efficiencyVSAvoidapparatus structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The cleaning apparatus is designed to handle multiple cleaning functions within a single device structure. The cleaning members can contact and clean different surfaces of the blade assembly, and the system integrates both cleaning and disinfectant dispensing functions, reducing the need for multiple separate devices while maintaining high cleaning efficiency.

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

Solution Approach 2:

The patent combines the cleaning members and disinfectant dispensing system into a single integrated apparatus. The cleaning members and nozzles are positioned to work together on the blade assembly, merging multiple cleaning functions into one unified device that improves efficiency without requiring multiple separate components.

Inventive Principle:
Principle #5Merging (Combining)
