Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If contactless communication is used between handle and cleaning head, then hygiene is improved by preventing cross-contamination, but reliability deteriorates due to signal interference from dirty surfaces

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidcross-contamination
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A magnetic field is introduced as an intermediary for data transmission between the handle and cleaning head, replacing direct contactless communication. The magnetic field penetrates dirty surfaces without being blocked by contamination, enabling reliable communication while maintaining the hygiene benefits of contactless operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The communication method is changed from electromagnetic radio waves to magnetic field coupling. This parameter change in the physical medium enables transmission through contaminated environments while maintaining contactless operation, thus improving both reliability and hygiene.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If tactile sensor device is added to handle, then ease of operation is improved through intuitive touch control, but device complexity increases

Engineering Contradiction:
Improvecontrol intuitivenessVSAvoidsensor system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The tactile sensor device enables the user to directly interact with and control the cleaning device through natural touch gestures on the handle. The system interprets user intent through simple touch patterns (duration, position, repetition) without requiring complex interfaces or training, making the device serve itself through intuitive human interaction.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Physical mechanical controls (buttons, switches, dials) are replaced with a tactile sensor system that detects touch gestures. This substitution provides more intuitive control while consolidating multiple control functions into a single sensor device, actually reducing overall control system complexity.

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