High-Strength Hinge Cover for Lightweight Foldable Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The formation of imprints on the hinge cover due to the internal structure of foldable-screen terminals affects the overall aesthetics and degrades user experience when the hinge cover is manufactured lightweight.
Innovation Solution
The hinge cover is made of a material with a yield strength greater than 300 MPa, such as titanium alloy or high-strength steel, and features a threaded column for connection to the structural member, along with design elements like shielding plates and positioning columns to enhance strength and reliability, while maintaining a lightweight design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the hinge cover is made lightweight, then the weight is reduced, but imprints are formed on the hinge cover affecting aesthetics
Solution Approach 1:
The patent changes the material parameter (yield strength) to greater than 300 MPa, enabling the hinge cover to maintain shape integrity and resist imprint formation while keeping the overall weight low through optimized thickness (less than 0.8 mm)
Solution Approach 2:
The patent specifies using titanium alloy or high-strength steel materials that combine low density with high yield strength, creating a composite material solution that simultaneously achieves lightweight construction and high resistance to deformation
2Weight of moving object
If the hinge cover is made lightweight with reduced thickness, then the weight is reduced, but the strength to withstand connection forces is compromised
Solution Approach 1:
The patent changes the material yield strength parameter to greater than 300 MPa and optimizes the thickness parameter to less than 0.8 mm, achieving a parameter combination that provides sufficient strength for threaded connections while minimizing weight
Solution Approach 2:
The patent introduces a threaded column structure that concentrates the connection function in a localized region, allowing the majority of the hinge cover to maintain thin, lightweight construction while the threaded column provides the necessary strength for withstanding connection forces
