Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional user interface methods (key pad, buttons, jog keys, touch pad) are used, then the device can perform various operations, but the number of input steps increases and user convenience deteriorates

Engineering Contradiction:
Improveuser convenienceVSAvoidnumber of input steps
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces mechanical input systems (key pads, buttons, jog keys, touch pads) with a motion-based control system using gyro sensors and acceleration sensors to detect device orientation and movement, thereby reducing the number of physical input steps and improving ease of operation

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

Solution Approach 2:

The patent introduces motion detection technology as an intermediary between user intent and device operation. The gyro sensor and acceleration sensor detect device movement, and the controller translates this motion into corresponding UI operations, reducing direct manual input steps

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If multiple input operations are required for each instruction, then precise control is achieved, but the operation complexity increases and user experience deteriorates

Engineering Contradiction:
Improveoperation simplicityVSAvoidinput operation complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent enables the device to automatically detect and interpret user intent through motion sensors. The system self-services by detecting device orientation changes and automatically triggering corresponding UI operations without requiring users to navigate through multiple input steps or menus

Inventive Principle:
Principle #25Self-service

3Ease of operation

If traditional button-based interfaces are used, then device functionality is maintained, but the interface intuitiveness decreases and user satisfaction deteriorates

Engineering Contradiction:
Improveinterface intuitivenessVSAvoidinstruction performance speed
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent substitutes traditional button-based mechanical interfaces with a motion recognition system that uses gyro sensors to detect device orientation and movement patterns, translating physical motion directly into UI operations to improve intuitiveness and instruction performance speed

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