Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices face damage due to stress when bent, as the condensing and tensile forces generated during bending can lead to degradation in quality.
Innovation Solution
An apparatus and method for manufacturing display devices that minimizes stress by using a bending unit with linear and rotating movement units to carefully bend and attach components, including a stage with location detecting units and a pressurizer to prevent warping, allowing for precise control of the bending process.

Engineering Contradiction Analysis
1Shape
If a member is bent using conventional methods, then the member can be curved to a predetermined angle, but excessive stress is applied to the member causing damage and quality degradation
Solution Approach 1:
The bending unit employs dynamic control through multiple linear movement units (first, second, third) and rotating units that can adjust the bending process in real-time. The system dynamically modifies bending parameters during the process to minimize stress concentration, allowing the member to be curved to a predetermined angle while maintaining strength through continuous adaptation of the bending force distribution.
Solution Approach 2:
The system changes multiple parameters during the bending process including the position of the bending unit via linear movement units, the rotation angle through rotating units, and the bending speed. By dynamically adjusting these parameters, the system optimizes the stress distribution on the member throughout the bending process, preventing excessive stress while achieving the desired curved shape.
2Manufacturing precision
If multiple movement units are used to control the bending process precisely, then stress can be minimized, but the device complexity increases
Solution Approach 1:
The bending unit is segmented into multiple independent functional modules: first linear movement unit for vertical positioning, second linear movement unit for horizontal positioning, third linear movement unit for depth control, rotating units for angular adjustment, and a pressurizer for stress management. Each segment performs a specific function, allowing precise control of the bending process while maintaining modularity that simplifies the overall system architecture and control strategy.
