Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional electric kettles use multiple buttons for temperature setting, then temperature control functionality is achieved, but ease of operation deteriorates

Engineering Contradiction:

Solution Approach 1:

The patent replaces the mechanical button-pressing system with an optical detection system. A light source projects a light beam, and a sensor detects the angular position of the container body by measuring the reflected light. This allows temperature selection through simple rotational movement rather than complex button sequences, directly improving ease of operation while maintaining temperature control functionality.
