Solution Overview

Problem

Existing electronic panels face challenges in maintaining uniform sensitivity across their active areas and are prone to cracks, which can compromise their reliability and functionality.

Innovation Solution

The electronic panel incorporates a crack detecting pattern with a line-symmetrical shape, including extension portions and connecting portions, located along the edge of a through hole, to enhance sensitivity uniformity and detect cracks, thereby improving reliability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a through hole is formed in the electronic panel for sensing external input, then sensing functionality is improved, but the risk of cracks increases

Engineering Contradiction:
Improvesensing functionalityVSAvoidcrack resistance
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies preliminary action by pre-forming a crack detecting pattern in the through hole before cracks actually occur. This pattern includes conductive lines arranged in specific configurations that enable early detection of crack formation. The pattern is created during manufacturing and remains dormant until crack development alters the electrical properties, allowing preventive maintenance before failure.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback by using the crack detecting pattern to monitor the structural integrity of the through hole. When a crack forms, it disrupts the conductive paths in the pattern, changing electrical resistance or continuity. This feedback signal allows the system to detect crack presence and report it, enabling timely intervention to prevent complete failure.

Inventive Principle:
Principle #23Feedback

2Area of stationary object

If the active area is increased to improve display quality, then uniformity of sensitivity becomes harder to maintain

Engineering Contradiction:
Improveactive areaVSAvoiduniformity of sensitivity
Core Design Contradiction:
Area of stationary objectVSManufacturing precision

Solution Approach 1:

The patent applies local quality by implementing the crack detecting pattern specifically in the through hole area, which is a localized region with different functional requirements. The pattern is positioned to monitor critical stress points around the through hole without interfering with the overall active area. This localized approach allows the through hole to maintain its sensing function while receiving specialized crack monitoring.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent uses segmentation by dividing the crack detection function into separate conductive lines and patterns within the through hole structure. The crack detecting pattern is segmented into multiple conductive elements arranged in specific configurations, allowing independent optimization of each segment's electrical properties while maintaining overall functionality. This segmentation enables precise control over sensitivity uniformity in the active area.

Inventive Principle:
Principle #1Segmentation

3Reliability

If the crack detecting pattern is added to the electronic panel, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improvecrack detection capabilityVSAvoidstructural complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing the crack detecting pattern to serve multiple functions: it acts as both a structural element within the through hole and a sensing mechanism for crack detection. The conductive lines in the pattern can be integrated with existing electrical connections in the electronic panel, allowing the same structure to fulfill both mechanical support and electrical monitoring roles. This multi-functionality reduces the need for separate dedicated crack detection components.

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

Solution Approach 2:

The patent implements self-service by designing the crack detecting pattern to automatically detect cracks without requiring external intervention. The pattern uses the electronic panel's existing electrical systems to monitor its own structural integrity through electrical property changes. When cracks form, the pattern self-detects the disruption and can trigger alerts or shutdowns, eliminating the need for separate inspection systems or manual checking.

Inventive Principle:
Principle #25Self-service
