Solution Overview

Problem

Touch panels often tilt and experience uneven pressing force distribution when pressed at positions other than the center, leading to instability and uneven support.

Innovation Solution

A support structure comprising a first component with first levers and pivot portions, and a second component with levers and assembly parts, pivotally connected to form scissor lift structures, providing stable support for the touch panel by evenly distributing pressing forces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a common method of manufacturing a touch panel structure is to form two sets of touch electrodes on different base materials and then combine them together, then the touch panel can be manufactured with standard processes, but the touch panel tilts when pressed at positions other than the center position, causing uneven pressing force distribution

Engineering Contradiction:

Improvemanufacturing process standardizationVSAvoidtouch panel stability

Core Design Contradiction:

Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The support structure is divided into multiple scissor-like mechanisms with pivot portions, allowing each segment to independently adjust and distribute force evenly across the touch panel surface, preventing tilting while maintaining manufacturing feasibility

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The scissor-like support structure acts as a mechanical counterbalance system that compensates for uneven pressing forces by redistributing them through the pivot portions and levers, maintaining horizontal stability regardless of where the touch panel is pressed

Inventive Principle:

Principle #8Anti-weight (Counterweight)

2Ease of operation

If the touch panel is pressed at a position other than the center position, then user input can be registered, but the touch panel tilts and the pressing force is unevenly distributed, reducing input accuracy

Engineering Contradiction:

Improveuser input capabilityVSAvoidpressing force distribution uniformity

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The support structure uses dynamic scissor-like mechanisms with pivot portions that can adaptively adjust their configuration in response to pressing forces from any position, automatically maintaining even force distribution and horizontal stability during user interaction

Inventive Principle:

Principle #15Dynamics

3Stability of the object's composition

If a support structure with scissor-like mechanisms and pivot portions is used, then the pressing force is evenly distributed and stability is improved, but the device complexity increases

Engineering Contradiction:

Improvetouch panel stabilityVSAvoidsupport structure complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The scissor-like support structure with pivot portions serves multiple functions simultaneously: it provides mechanical support, distributes pressing forces evenly, maintains horizontal stability, and enables adaptive adjustment to pressing positions, reducing the need for additional separate components

Inventive Principle:

Principle #6Universality (Multi-functionality)
