Solution Overview

Problem

Users face inefficiencies in navigating complex hierarchical structures of folders on touch panel devices, requiring repetitive operations to open and close folders across multiple hierarchies, which is time-consuming and labor-intensive.

Innovation Solution

An input device with a load detection unit and control unit that differentiate between pressing loads to control the opening and closing of folders, using predefined load standards to simplify folder operations by detecting changes in pressing force, allowing for sequential opening and closing of folders with reduced user effort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a touch panel is used to display and interact with folder hierarchies, then the device can provide intuitive operation and flexible configuration, but users must repeatedly touch to open and close folders across multiple hierarchies, increasing operation time and effort

Engineering Contradiction:
Improveintuitive operationVSAvoidoperation time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent applies the dynamics principle by enabling the touch panel to detect varying pressing loads and dynamically respond with different folder navigation actions. Instead of a static single-action touch interface, the system adapts its behavior based on the intensity of the pressing force, allowing users to navigate deeper folder hierarchies with stronger presses and close folders with weaker presses, thereby reducing the number of discrete touch operations needed

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by using the pressing load intensity as a variable parameter to differentiate between various folder operations. The control unit interprets different pressing load thresholds to trigger different actions (open parent folder, open child folder, close folder), transforming a single-parameter touch interface into a multi-parameter control system that reduces operational steps while maintaining intuitive interaction

Inventive Principle:
Principle #35Parameter changes

2Productivity

If multiple pressing load thresholds are implemented to control folder operations, then folder navigation becomes more efficient with fewer operations, but the device complexity increases due to additional detection and control mechanisms

Engineering Contradiction:
Improvefolder navigation efficiencyVSAvoiddetection and control mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies the universality principle by making the existing touch panel serve multiple functions: it not only detects the presence of a touch but also measures pressing load intensity and determines touch duration. This multi-functional use of the touch panel eliminates the need for separate hardware components, allowing the system to differentiate between folder opening, closing, and navigation actions while maintaining a simple overall device structure

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

Solution Approach 2:

The patent implements mechanics substitution by replacing what would traditionally require separate mechanical buttons or switches for different folder operations with a single electronic touch panel system. The control unit processes varying electrical signals from the touch panel based on pressing load intensity, substituting multiple mechanical input devices with one electronic system that achieves the same functional complexity through software-based differentiation

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