Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If bulky input devices (key buttons or touch panels) are installed in the wearable device, then user input functionality is improved, but device compactness and wearability are worsened

Engineering Contradiction:
Improveuser input functionalityVSAvoiddevice compactness
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The patent merges the input device functionality with the existing support frame structure. The support frame serves dual purposes: providing structural support for wearing the device and housing the input mechanism. This integration eliminates the need for separate bulky input devices while maintaining input functionality through the motion sensor and protrusion structure combination.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces traditional mechanical input devices (key buttons or touch panels) with a motion sensor-based detection system. The motion sensor detects user inputs through movement patterns caused by the protrusion structure, substituting complex mechanical input mechanisms with a more compact sensor-based system that achieves the same functional goal.

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

2Reliability

If motion sensor and communication antennas are mounted in the device, then sensor functionality is improved, but available mounting space for other components is worsened

Engineering Contradiction:
Improvesensor functionalityVSAvoidavailable mounting space
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The patent applies local quality by positioning the protrusion structure at specific locations on the support frame where it can effectively interact with the motion sensor. The protrusion patterns are strategically placed to maximize input detection capability while minimizing interference with other components. This localized structural modification enables input functionality without requiring additional mounting space throughout the entire device.

Inventive Principle:
Principle #3Local quality
