1Reliability

If window substrates are placed in a load carrier for chemical reinforcement, then the window substrates can undergo chemical reinforcement process, but the contact area and contact time between window substrates and load carrier increase causing deformation

Engineering Contradiction:
Improvechemical reinforcement processVSAvoidsurface quality
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The load carrier's support surface is segmented into multiple protrusions instead of a continuous flat surface. Each protrusion creates a localized contact point, dividing the overall contact area into numerous small discrete areas. This segmentation allows the window substrate to undergo chemical reinforcement while minimizing the total contact area and preventing deformation-induced surface quality degradation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The load carrier is designed with movable wires that can dynamically adjust the position and configuration of protrusions. During the chemical reinforcement process, the wires can move to optimize contact points, ensuring minimal contact area while maintaining proper positioning of the window substrate. This dynamic adjustment capability prevents deformation while enabling the reinforcement process.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If window substrates are held in contact with load carrier during processing, then the substrates can be properly positioned and supported, but the contact time increases causing deformation

Engineering Contradiction:

Core Design Contradiction:
Stability of the object's compositionVSManufacturing precision

Solution Approach 1:

The load carrier employs periodic contact through movable wires that can adjust their position cyclically during the chemical reinforcement process. The wires make contact at specific intervals and positions, providing necessary support and positioning while minimizing continuous contact time. This periodic action pattern ensures substrate stability during processing while preventing deformation caused by prolonged contact.

Inventive Principle:
Principle #19Periodic action

AI summary

A window manufacturing system includes a first wire, a second wire spaced apart from the first wire, a controller moving the first wire up and down and the second wire up and down, and a load carrier connected to the first wire and the second wire. Window substrates are disposed on the load carrier. The controller moves the first wire and the second wire in opposite directions to each other.
