Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a display device with a stable and rigid foldable stand that can easily mount and support large devices, ensuring stability and ease of use in various locations without requiring additional stands.
Innovation Solution
The display device incorporates a foldable stand panel with an elastic hinge module and a button mechanism, featuring a latch system and hinge spring for adjustable angles, which provides rigidity and semi-automatic opening and closing functionality, allowing for secure mounting and flexible positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a foldable stand is integrated into the display device, then ease of mounting and portability are improved, but the structural complexity and difficulty of ensuring stability under load increase
Solution Approach 1:
The stand is divided into a stand panel and a support panel connected by a hinge module, allowing independent movement and positioning of each segment. This segmentation enables the stand to be folded for portability while maintaining stability when deployed, resolving the contradiction between ease of mounting and structural complexity.
Solution Approach 2:
The hinge module incorporates a hinge spring that provides elastic force to automatically adjust and maintain the stand panel at an optimal viewing angle. This dynamic mechanism eliminates the need for complex manual adjustment systems while ensuring stability under load, addressing both ease of operation and structural complexity.
2Stability of the object's composition
If a rigid joint structure is used in the stand, then stability and load-bearing capacity are improved, but the ease of folding and portability deteriorates
Solution Approach 1:
The hinge module uses a spring-based elastic hinge that provides continuous adaptive support force to the stand panel. This dynamic elastic structure maintains rigid support characteristics when loaded while allowing smooth folding motion when not in use, resolving the contradiction between stability under load and ease of folding.
Solution Approach 2:
The hinge spring changes its elastic force parameter based on the stand's position and load conditions. When the stand is deployed, the spring provides sufficient force to maintain stability under load; when folding, the spring allows controlled movement. This parameter adaptation resolves the contradiction between rigid support and flexible folding.
3Reliability
If multiple components are added to ensure stand stability, then reliability is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The hinge module combines the hinge mechanism, spring element, and mounting structure into an integrated assembly that couples the stand panel to the back cover. This merging of components ensures reliable stability functionality while reducing the total number of separate parts that need to be manufactured and assembled, thereby improving ease of manufacture.
Solution Approach 2:
The hinge module serves multiple functions simultaneously: it provides the structural connection between stand panel and back cover, supplies elastic support force through the hinge spring, enables folding motion, and maintains stability under load. This multi-functionality reduces the need for separate components, simplifying manufacturing while ensuring reliability.
