Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional manufacturing apparatus is used for flexible display devices, then the device can be manufactured, but the stability of assembly process deteriorates leading to potential damage and quality issues
Solution Approach 1:
The pad is positioned between the first jig and the second member (electric panel) to provide cushioning and protection before assembly forces are applied. This prevents direct contact and potential damage between rigid components and the flexible electric panel, thereby improving assembly stability and preventing component damage.
Solution Approach 2:
The pad is made of flexible material (silicone, urethane, or rubber) that can deform to accommodate the bent shape of the electric panel while maintaining protective contact. This flexibility allows the pad to conform to the curved surface of the flexible display components, providing stable support without causing damage.
2Manufacturing precision
If bent-shaped components are assembled using conventional methods, then assembly can be completed, but manufacturing precision deteriorates due to unstable positioning
Solution Approach 1:
The pad features a curved upper surface that matches the bent shape of the electric panel. This curvature allows the pad to conform precisely to the flexible component's shape, providing stable positioning and improving attachment accuracy of bent-shaped components during assembly.
Solution Approach 2:
The pad acts as an intermediary element between the first jig and the second member, providing a stable interface for positioning bent-shaped components. The pad's flexible nature and curved surface allow it to mediate the assembly process, ensuring accurate positioning while accommodating the flexibility of the components.
3Productivity
If forces are concentrated during assembly of flexible components, then assembly speed can be maintained, but manufacturing precision deteriorates due to component damage
Solution Approach 1:
The pad provides cushioning before assembly forces are applied, distributing the impact and pressure over a larger area. This prevents concentration of forces that could damage flexible components, allowing assembly to proceed at normal speed while maintaining component quality and manufacturing precision.
Solution Approach 2:
The pad's material properties (silicone, urethane, or rubber) provide varying degrees of compliance and force distribution. By selecting appropriate materials, the system can absorb assembly forces and distribute them evenly, preventing force concentration while maintaining assembly productivity and component quality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution improves the stability and quality of display devices by ensuring precise alignment and secure attachment of components, reducing the risk of damage and enhancing the adhesive force between the window and electric panel, thus facilitating the production of flexible display devices with improved performance.
Implementation Method 1
The pad includes at least one of silicone, urethane, and rubber. The upper surface is curved to protrude towards the first jig with respect to a plane surface defined by the first direction and a second direction crossing the first direction.
Implementation Method 2
The groove includes a bottom portion which is flat and sidewalls bent and extending from the bottom portion, and the sidewalls include a first sidewall having a curved shape. The lower surface includes a plane portion facing the bottom portion and concave portions extending from the plane portion to connect the plane portion and the connection surfaces.
