Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual cleaning methods are used, then flexibility and adaptability to different surfaces are maintained, but labor intensity increases, safety risks arise especially for high buildings, and cleaning consistency deteriorates

Engineering Contradiction:

Improvelabor intensityVSAvoidcleaning consistency

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The cleaning system performs cleaning operations automatically without human intervention. The robotic device navigates autonomously, dispenses cleaning agents, and executes cleaning tasks based on pre-programmed sequences, making the system self-sufficient and eliminating the need for manual operation while ensuring consistent results

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Manual mechanical cleaning operations are replaced by an automated robotic system equipped with specialized end effectors. The robot substitutes human labor with programmable mechanical systems that deliver consistent, repeatable cleaning actions across all surfaces

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If manual cleaning is performed on high buildings, then accessibility to all surfaces is achieved, but safety risks and health hazards increase significantly

Engineering Contradiction:

Improvesurface accessibilityVSAvoidsafety risks

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The robotic cleaning system autonomously performs cleaning tasks on high buildings without requiring human workers to physically access dangerous areas. The robot navigates independently, eliminating exposure to heights and associated safety risks while maintaining full accessibility to building surfaces

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The robotic device serves as an intermediary between the cleaning task and the building surface, performing all operations that would otherwise require human workers to access hazardous environments. This intermediary system transfers the safety risk from human workers to a controlled robotic platform

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If cleaning is delayed due to weather or time constraints, then resource availability improves, but cleaning frequency decreases and hygiene standards deteriorate

Engineering Contradiction:

Improvecleaning speedVSAvoidcleaning frequency

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The automated cleaning system operates continuously without interruption by weather conditions or time constraints. The robotic device can perform cleaning tasks in various environmental conditions and maintains consistent operation schedules, eliminating delays that would occur with manual cleaning and enabling more frequent cleaning cycles

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

Replacing manual cleaning with an automated robotic system eliminates the time loss associated with worker availability, weather-related delays, and scheduling constraints. The robot provides continuous, reliable operation that increases both cleaning speed and frequency

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

An automatic touchless washing machine is used for washing and cleaning all various types of buildings and windows. The machine dispenses, by a spray arm, high pressure water, chemical liquid, or dry-air from various storage tanks to wash areas of exterior surfaces of a building or a window. A controller controls the machine to automatically perform a wash program, step by step, without using hands. The controller further controls one or more wash functions by coordinating movements of the spray arm.
