Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a touch screen is used as the input device, then the device structure is simplified and no separate input device is needed, but the user interface becomes awkward and does not fully utilize device features

Engineering Contradiction:
Improvedevice structureVSAvoiduser interface
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent detects and utilizes touch pressure as an additional parameter beyond simple touch location. By measuring the pressure magnitude of user input, the system enables more nuanced control of GUI elements including size adjustment, zoom levels, movement speed, and selection of different functions based on pressure thresholds, thereby enriching the user interface capabilities without adding hardware complexity

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system dynamically adjusts GUI element properties based on the detected touch pressure. For example, pressing harder on a GUI element increases its size or zoom level, while varying pressure controls movement speed or triggers different actions. This dynamic response to pressure input transforms the static touch screen interaction into a more expressive and intuitive interface

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If conventional key buttons are used, then the user interface is intuitive and easy to operate, but the device structure becomes more complex and requires separate input devices

Engineering Contradiction:
Improveuser interfaceVSAvoiddevice structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The touch screen is designed to perform multiple functions: it serves as both the display interface and the input device. By detecting touch pressure in addition to touch location, the single touch screen component replaces the functionality of separate physical buttons, knobs, or dials that would otherwise be needed for controlling GUI element properties, achieving multi-functionality without increasing hardware complexity

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

Solution Approach 2:

The patent replaces mechanical input devices (physical buttons, knobs, or dials) with a touch-based system that detects pressure through capacitive or resistive sensing. This substitution eliminates the need for separate mechanical components while maintaining or enhancing the intuitiveness of the user interface through direct touch interaction with the display surface

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

3Adaptability or versatility

If touch pressure detection is implemented, then more UI control options are available (size, zoom, speed, etc.), but the system complexity increases

Engineering Contradiction:
ImproveUI control optionsVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system leverages touch pressure as an additional controllable parameter to adjust multiple UI properties simultaneously. A single pressure value can control GUI element size, zoom level, movement speed, or trigger different functions, providing versatile control options without requiring separate controls for each parameter. This efficient use of the pressure parameter maximizes adaptability while minimizing system complexity

Inventive Principle:
Principle #35Parameter changes
