Grooved Display Support Plate for Lower Weight and Impact Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bendable protective cover plates in electronic devices suffer from poor impact resistance due to their small thickness, leading to increased weight and overall device weight when support plates are used for reinforcement.
Innovation Solution
A display assembly with a support plate featuring grooves on its non-light-exit side, where the grooves have a depth less than the thickness of the plane part, ensuring impact resistance while reducing weight by staggering attachment sub-parts and grooves to facilitate module pickup without air leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a support plate is added to protect the flexible screen, then impact resistance is improved, but weight increases
Solution Approach 1:
The support plate incorporates an array of grooves that create a porous-like structure, reducing the overall material volume and weight while maintaining structural integrity. The grooves allow the support plate to be lighter yet still provide adequate impact protection for the flexible screen.
Solution Approach 2:
The support plate is divided into multiple regions: plane parts that provide structural support and groove parts that reduce weight. This segmentation allows different areas to serve different functions - the plane parts maintain strength while the groove parts reduce material usage and overall weight.
2Weight of moving object
If grooves are added to reduce weight, then weight decreases, but structural strength may be compromised
Solution Approach 1:
Different regions of the support plate have different properties: plane parts with full material density for strength, and groove parts with reduced material for weight savings. This local differentiation optimizes the balance between weight and structural strength, ensuring each area has the appropriate characteristics for its function.
Solution Approach 2:
The grooves are designed with specific depth limitations (less than the thickness of the plane part) to remove sufficient material for weight reduction while retaining enough material to maintain adequate structural strength. This partial removal of material achieves the weight reduction goal without excessive compromise to strength.
3Ease of operation
If attachment sub-parts are staggered with grooves, then module pickup is facilitated without air leakage, but manufacturing complexity increases
Solution Approach 1:
The attachment sub-parts are extracted as distinct functional elements from the continuous plane surface, creating discrete attachment zones that are strategically positioned relative to the grooves. This extraction facilitates module pickup operations while the staggered arrangement prevents air leakage paths.
