Solution Overview

Problem

Conventional touchpads in notebook computers, especially those of smaller sizes, fail to meet user demands for diverse input modes as they are limited in operating space, necessitating the need for larger touchpads with multiple input options to enhance user experience.

Innovation Solution

An electronic device with a display panel, touch component, and processor that dynamically sets operation positions for input components, allowing for user-defined multi-mode touch operation interfaces by establishing link setting information between input components and effective input regions, enabling various functions such as stylus operations, scrolling, dial adjustments, and shortcut key functions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If the touchpad size is increased to provide more operating space, then the input area is improved, but the device portability and compactness deteriorate

Engineering Contradiction:
Improvetouchpad input areaVSAvoiddevice compactness
Core Design Contradiction:
Area of moving objectVSVolume of moving object

Solution Approach 1:

The touchpad is designed to support multiple input modes including traditional pointer control, stylus input, and gesture operations on a single surface. Different input components share the same physical space, allowing the touchpad to function as both a pointing device and a stylus-responsive surface without requiring separate physical areas

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

Solution Approach 2:

The system dynamically adjusts the effective input region and operational characteristics of the touchpad based on the detected input type. When a stylus is detected, the system activates stylus-specific input modes and adjusts sensitivity parameters, whereas traditional finger input triggers pointer control modes, allowing the same physical space to adapt to different input requirements

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple input modes are combined to meet multi-user scenarios, then the versatility is improved, but the device complexity increases

Engineering Contradiction:
Improveinput mode diversityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple input processing systems are merged into a unified touchpad interface. The stylus input system, gesture recognition system, and traditional pointer control system all operate on the same touch-sensitive surface, sharing common hardware resources and processing pathways to reduce overall system complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

A processor acts as an intermediary that receives input signals from the touchpad, identifies the input type (finger touch, stylus tip, gesture), and routes the signal to the appropriate processing mode. This centralized mediation simplifies the system architecture by providing a single point of decision-making rather than requiring separate dedicated systems for each input mode

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If the touchpad supports both traditional pointer input and stylus input, then the ease of operation is improved, but the measurement precision of input detection deteriorates

Engineering Contradiction:
Improveinput accessibilityVSAvoidinput detection accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The touchpad implements different detection sensitivity zones and thresholds based on the detected input type. When a stylus is detected, the system activates higher-precision detection parameters optimized for tip localization, whereas finger input triggers sensitivity parameters optimized for gesture recognition and broader touch areas, ensuring optimal precision for each input mode

Inventive Principle:
Principle #3Local quality
