Hinge Structure with Segmented Positioning for Laptop Display Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hinge structures in electronic devices face challenges in balancing the torsion force required to lock and unlock the opened/closed state, causing inconvenience in gaming notebooks due to high torsion force needs and instability in consumer notebooks due to low torsion force, leading to unwanted rotation and dropping of the display screen.
Innovation Solution
A hinge structure featuring a shaft, first and second fixing components, first and second positioning components with a positioning elastic piece and circularly arranged slots, allowing for easy opening with minimal force and secure closing with greater force by engaging the elastic piece in slots, preventing unwanted rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the torsion force of the hinge structure is increased to properly lock the opened/closed state in gaming notebooks, then the locking reliability is improved, but the ease of operation deteriorates due to inconvenience in opening and closing
Solution Approach 1:
The hinge structure is segmented into multiple functional components: a first positioning component with a positioning elastic piece for easy opening, and a second positioning component with positioning slots for secure locking. This segmentation allows different sections to perform different functions - the first positioning component reduces opening force while the second positioning component ensures reliable locking through engagement of the elastic piece with positioning slots.
2Ease of operation
If the torsion force of the hinge structure is decreased to improve ease of operation in smaller notebooks, then the ease of opening and closing is improved, but the locking reliability deteriorates as the hinge may not properly lock the opened/closed state
Solution Approach 1:
The hinge structure divides locking functions into two segments: the first positioning component handles the opening action with minimal force requirement, while the second positioning component provides the locking function through slot engagement. This segmentation ensures that even with lower torsion force, the opening operation remains easy while the locking reliability is maintained through the mechanical engagement of the elastic piece with the positioning slots.
Solution Approach 2:
The positioning elastic piece acts as an intermediary between the first and second positioning components. During opening, it allows easy movement; during closing, it engages with the positioning slots to transfer and secure the locking force, ensuring reliable state retention even with reduced overall torsion force in the hinge structure.
3Device complexity
If the hinge structure uses a simple locking mechanism, then the device complexity is reduced, but the stability deteriorates as the display screen may rotate and drop when the notebook is opened
Solution Approach 1:
The positioning mechanism is segmented into two functional parts: the first positioning component that facilitates opening motion and the second positioning component with circularly arranged positioning slots that provide stable locking. This segmentation achieves display stability through the slot engagement mechanism while keeping the overall structure relatively simple and avoiding complex multi-component systems.

Function Achieved in This Case
The design reduces the force required to open the device while ensuring a secure closed state, preventing the display from rotating and dropping, and requires more force to close, enhancing operational convenience and stability.
