Movable Voltage-Application Fixture for Liquid Crystal Panel Substrates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing voltage-application fixtures in liquid crystal panel manufacturing are fixed and cannot be adjusted to accommodate different substrate sizes, leading to increased design costs, workload, and productivity losses due to the need for new fixtures with each product change.
Innovation Solution
A movable voltage-application fixture apparatus with a transmission unit comprising a linkage structure, rail structure, and driving component allows for adjustable positioning of voltage-application probes to accommodate various substrate sizes, enabling shared use of fixtures and reducing change operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed voltage-application fixture is used, then the structure is simple and stable, but it cannot accommodate different substrate sizes and requires new fixtures for each product
Solution Approach 1:
The voltage-application fixture is transformed from a fixed structure to a movable one. The fixture can be positioned at different locations along the substrate and adjusted to contact voltage-application terminals at different positions, enabling the same fixture to accommodate various substrate sizes and terminal positions through dynamic repositioning rather than requiring multiple fixed fixtures
Solution Approach 2:
A single voltage-application fixture is designed to serve multiple functions by making it movable and adjustable. The fixture can be reused across different substrate sizes and product types by changing its position and orientation, eliminating the need to purchase new fixtures for each new product development
2Productivity
If a fixed voltage-application fixture is used, then the fixture position is stable, but production line changeover time increases and productivity decreases
Solution Approach 1:
The fixture's movability allows rapid repositioning between different substrate sizes and terminal positions. Instead of time-consuming replacement operations, the same fixture can be quickly moved and reconfigured for new products, significantly reducing line-changing time and improving overall productivity
Solution Approach 2:
The voltage-application fixture is designed to be easily repositioned and reused without requiring complex replacement procedures. The fixture serves itself across different products through its adjustable design, reducing the need for manual intervention and fixture replacement operations
3Ease of manufacture
If a fixed voltage-application fixture is used, then the fixture is simple to manufacture, but design costs increase due to inability to share fixtures
Solution Approach 1:
By adding movement and adjustment capabilities to the fixture, it becomes a universal tool that can be manufactured once and reused across multiple products. The dynamic design allows the same fixture structure to adapt to different substrate sizes and terminal positions, reducing overall design and manufacturing costs through sharing
