Foldable Hinge Module Structure to Prevent Rotary Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable electronic devices face challenges in maintaining the integrity of their hinge structure, particularly in preventing the rotary structure from separating from the fixed structure in both flat and folded states, which affects portability and operability.
Innovation Solution
A hinge module with a specific design featuring a fixed structure and recesses with stoppers that guide and restrict the rotation of rotary structures within the hinge housing, ensuring they remain connected and preventing separation during folding and unfolding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stopper is provided on the fixed structure to prevent separation of the rotary structure, then the rotary structure is prevented from separating from the fixed structure, but it becomes difficult to insert the rotary structure into the fixed structure
Solution Approach 1:
The hinge structure is divided into multiple functional components: a fixed structure, a rotary structure, and a stopper structure. The stopper is separated as an independent component that can be positioned strategically to prevent separation while allowing insertion. This segmentation enables the stopper to serve its restraining function without creating assembly difficulties for the overall hinge assembly.
Solution Approach 2:
The stopper acts as an intermediary element between the fixed structure and the rotary structure. It is configured to engage with the rotary structure at specific positions to prevent separation, while its design allows it to be bypassed or engaged smoothly during the insertion process. The stopper serves as a mediating component that enables both secure attachment and ease of assembly.
2Reliability
If the stopper protrudes far from the bottom surface to effectively prevent separation, then the prevention of separation is improved, but the receiving groove must be deeper and the structure more complex
Solution Approach 1:
The stopper is designed with dynamic engagement characteristics, allowing it to contact the rotary structure at optimal positions during rotation. The stopper protrudes from the bottom surface at a distance that enables effective separation prevention while the rotary structure rotates about the virtual axis. This dynamic design allows the stopper to engage only when necessary, reducing the need for deep receiving grooves and simplifying the overall structure.
Solution Approach 2:
The stopper engagement mechanism utilizes the rotational dimension of the hinge structure. Rather than requiring a deep vertical engagement, the stopper prevents separation by engaging the rotary structure in the rotational path, utilizing the circular motion of the hinge to achieve separation prevention with minimal protrusion distance and shallow receiving grooves.
