Chamfered Flange Groove Design for Display Panel Impact Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in manufacturing due to potential impacts between the flange and the set bracket, which can transfer stress to the display panel and cover, affecting the quality and reliability of the device.
Innovation Solution
The display device incorporates a flange design with specific geometric features, including a first part accommodated by a groove in the set bracket, a second part in contact with the first part, and a third part with a contact surface and a chamfered first corner portion, which reduces the likelihood of impact during manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the flange is positioned close to the set bracket for compact design, then device compactness is improved, but impact between flange and set bracket increases during manufacturing
Solution Approach 1:
The patent applies beforehand cushioning by introducing a groove structure in the set bracket and positioning the flange within this groove. The groove acts as a pre-designed cushioning space that absorbs impact during the manufacturing process, particularly during the rotation step where the flange might otherwise collide with the set bracket. This allows the flange to be positioned close to the set bracket for compactness while preventing harmful impacts.
Solution Approach 2:
The groove structure serves as an intermediary element between the flange and the set bracket. Instead of allowing direct contact between these two components, the groove mediates their interaction, providing a controlled interface that reduces impact forces during manufacturing operations while maintaining the compact arrangement.
2Volume of moving object
If the flange is positioned close to the display panel for compact design, then device compactness is improved, but stress transfer to the display panel increases
Solution Approach 1:
The groove structure in the set bracket provides beforehand cushioning that prevents direct transmission of stress from the flange to the display panel. By accommodating the flange within the groove, the structure absorbs and distributes stress forces, preventing them from being transferred to the fragile display panel during manufacturing operations such as rotation.
3Ease of manufacture
If the flange structure is simplified for ease of manufacture, then manufacturing complexity is reduced, but impact protection capability is weakened
Solution Approach 1:
The patent applies segmentation by dividing the flange structure into distinct functional parts: the flange body and the groove structure in the set bracket. This segmentation allows each component to be manufactured independently with simple geometries, while their combined arrangement provides impact protection. The groove is formed as a separate feature in the set bracket, making both components easier to manufacture while maintaining protective functionality.
