Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a display component is added to show device state, then user understanding of device state is improved, but device complexity increases

Engineering Contradiction:
Improveuser understanding of device stateVSAvoiddevice complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The display component utilizes color changes to indicate different device states. Different colors represent different operational modes (e.g., heating mode, cleaning mode, rest mode), providing intuitive visual feedback without requiring complex text or graphical interfaces. This resolves the contradiction by conveying information simply and effectively while adding minimal complexity.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The display component provides visual feedback to users about the current device state, enabling them to understand and control the device more effectively. The feedback mechanism uses simple visual indicators that respond to device operational changes, creating a user-friendly interface that enhances understanding without significant complexity increase.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If touch classification based on pressure is implemented, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The touch input mechanism dynamically responds to different pressure levels, classifying touches as light, medium, or strong presses. This dynamic response enables multiple functions to be activated through varying touch intensities, enhancing ease of operation. The system adapts its behavior based on the detected pressure level, providing intuitive control without requiring complex mechanical structures.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The touch input component serves multiple functions by classifying touches based on pressure. A single touch interface can activate different operations (e.g., mode selection, parameter adjustment, confirmation) depending on the pressure applied, eliminating the need for separate buttons for each function. This multi-functionality improves ease of operation while adding minimal complexity compared to having separate physical buttons for each operation.

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