OLED Panel Inclination Control via Angulated Pin and Hooking Groove
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing organic light emitting display panels lack a simple and cost-effective mechanism to control inclination, which is essential for optimal viewing angles in various applications such as monitors and TVs.
Innovation Solution
An apparatus comprising a rotation pin with an angulated body, a support arm with a connection hole and stopper, and a rotation part with an adhesion groove and hooking groove, which limits rotation to control the inclination of the panel by user-applied force rather than gravity, thereby maintaining set angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple support structure is used for the organic light emitting display panel, then the device complexity is reduced and material costs decrease, but the ability to control panel inclination is insufficient
Solution Approach 1:
The patent implements a nested structure where the rotation pin is inserted into the rotation part, the stopper is positioned within the adhesion groove, and the hooking groove engages with the stopper. This nesting arrangement allows multiple functional elements to be compactly integrated, providing inclination control capability while maintaining a simple overall structure and reducing material costs.
Solution Approach 2:
The patent transforms the static support structure into a dynamic one by enabling rotation of the rotation part around the rotation pin. The stopper and hooking groove mechanism allows the panel to be adjusted to different inclination angles while maintaining stability at each position, thus providing both simplicity and operational flexibility.
2Device complexity
If no rotation control mechanism is provided, then the structure remains simple, but the panel cannot maintain set inclination angles against external influences such as gravity
Solution Approach 1:
The stopper protruding under the connection hole and the hooking groove are designed to preemptively counteract the effect of gravity and other external forces. When the rotation part is rotated to a desired angle, the stopper engages with the hooking groove to prevent unintended rotation, thereby maintaining the set inclination angle without requiring complex active control mechanisms.
Solution Approach 2:
The rotation control mechanism is designed to be self-regulating. The stopper and hooking groove automatically engage at specific rotation positions, allowing the panel to maintain its inclination angle without external intervention. The structure itself provides the necessary constraint forces to counteract gravity and maintain stability.
3Reliability
If a complex inclination control mechanism is implemented, then reliable angle control is achieved, but material costs and manufacturing complexity increase
Solution Approach 1:
The inclination control function is segmented into distinct simple components: the rotation pin, the rotation part with adhesion groove and hooking groove, and the stopper. Each component has a specific, simple function, making them easy to manufacture individually. When assembled, these segments work together to provide reliable inclination control without requiring complex integrated mechanisms, thus reducing overall manufacturing cost.
Solution Approach 2:
The patent employs simple geometric features (grooves, protrusions, and holes) that can be easily formed through conventional manufacturing processes. These features replace the need for expensive specialized components, allowing reliable inclination control to be achieved through cost-effective manufacturing methods.
