Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing substrate production apparatus for display devices using the MMG method is limited in its ability to efficiently process glass substrates of different dimensions simultaneously, leading to increased complexity and decreased productivity due to the need for device replacement and separate processing lines.
Innovation Solution
A substrate production apparatus with two parallel production lines and a common buffer unit, along with a hand robot, allows for the simultaneous processing of glass substrates of different dimensions by transferring substrates between lines via a common buffer unit, enabling efficient exchange and processing without the need for constant device replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If device replacement and separate processing lines are used to process glass substrates of different dimensions, then processing capability for multiple dimensions is achieved, but operational complexity and device complexity increase
Solution Approach 1:
The patent implements a universal processing line where the same scribing, grinding, and cleaning devices can process glass substrates of different dimensions by using programmable control systems. The devices are designed with adjustable parameters and interchangeable tooling to accommodate various substrate sizes without requiring physical replacement of equipment, thereby achieving multi-functionality while maintaining operational simplicity.
Solution Approach 2:
The processing line incorporates dynamically adjustable components that can be reconfigured for different substrate dimensions through software control rather than physical reassembly. The system allows dynamic parameter adjustment (speed, pressure, tool position) based on the specific dimensions being processed, enabling versatility without increasing operational complexity.
2Adaptability or versatility
If device replacement and separate processing lines are used to process glass substrates of different dimensions, then processing capability for multiple dimensions is achieved, but productivity decreases
Solution Approach 1:
The patent establishes a continuous processing flow where glass substrates of different dimensions move through the scribing, grinding, and cleaning stages without interruption or device replacement. The programmable control system allows seamless transition between different substrate types, maintaining continuous operation and eliminating downtime associated with equipment changes, thereby preserving high productivity while achieving multi-dimensional processing capability.
3Adaptability or versatility
If constant device replacement is performed to handle different substrate dimensions, then adaptability to various dimensions is improved, but production flow is interrupted
Solution Approach 1:
The system is pre-configured with programmable parameters and tooling arrangements for multiple substrate dimensions. Before processing begins, the control system is programmed with the required dimensions, and the devices are pre-adjusted to the appropriate settings. This preliminary configuration eliminates the need for mid-production device replacement, allowing seamless handling of different substrate dimensions without interrupting the production flow.
