Solution Overview

Problem

The high cost and complexity of developing masks for touch products with special sizes and aspect ratios lead to inefficiencies in meeting small batch demands, making it difficult to produce touch screen products with both display and touch interaction functions efficiently.

Innovation Solution

A touch substrate manufacturing method that involves cutting a touch substrate of a conventional size to create a target substrate of a specific size without the need for a new mask, by adjusting the connection manner of the flexible printed circuit and touch IC, and potentially adjusting the film thickness of conductive materials to meet the required resistance values.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a mask plate is developed separately for each special size and aspect ratio touch product, then the display region requirements can be met, but the development cost increases significantly and profitability cannot be guaranteed for small batch demands

Engineering Contradiction:
Improvedisplay region requirementsVSAvoidmask development cost
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by using a single standardized mask plate design that can accommodate multiple different touch substrate sizes and aspect ratios. The mask plate is designed with a universal structure that allows it to serve various product configurations without requiring separate mask developments for each size, thereby reducing development costs while maintaining adaptability to different display region requirements.

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

Solution Approach 2:

The patent segments the touch substrate manufacturing process by separating the mask plate development from the substrate size customization. The standardized mask plate handles the common patterning functions while the substrate size and aspect ratio variations are managed through other means such as substrate selection and positioning, thereby reducing the complexity of mask development.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If a new mask plate is developed for each special size touch product, then the specific size requirements can be satisfied, but the production cycle increases and market responsiveness decreases

Engineering Contradiction:
Improvetouch substrate size precisionVSAvoidproduction cycle
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-developing and standardized mask plates that can be immediately used for production. Instead of developing new masks for each custom size requirement, the standardized masks are prepared in advance and can be quickly applied to different substrate sizes, thereby reducing the production cycle time while maintaining manufacturing precision through the standardized design.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The universal mask plate design allows the same mask to serve multiple product configurations, eliminating the need for time-consuming mask developments for each size variation. This multi-functional approach enables faster production cycle while maintaining the required precision for different touch substrate sizes.

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

3Ease of operation

If touch and display functions are integrated in the same device, then user experience is improved, but the demand for such integrated products remains insufficient compared to separate display products

Engineering Contradiction:
Improveuser experienceVSAvoidbatch demand
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent applies universality by developing a standardized mask plate system that can serve both display and touch functionality. The same standardized mask can be used for producing touch substrates with different sizes and aspect ratios, enabling the manufacturing of integrated touch-display products without requiring separate specialized masks, thereby supporting the production of multi-functional devices.

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