Foldable Hinge Assembly With Independent Arc-Slide Brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable assemblies in electronic devices face challenges with low assembly efficiency and inaccurate dimensions of arc-shaped slides, requiring complex adjustments and high precision in installation.
Innovation Solution
The foldable assembly features independent upper brackets for each sliding part, allowing separate installation and adjustment, along with a floating plate and groove structure to enhance stability and reduce thickness, and uses a spring for smooth operation, along with positioning holes and protrusions for quick alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the upper bracket and lower bracket are installed and fastened by using bolts to form arc-shaped slides, then the foldable assembly can achieve folding and unfolding function, but the requirements on accuracy of processing and installation dimensions of the upper bracket are relatively high and installation efficiency is relatively low
Solution Approach 1:
The upper bracket is divided into multiple independent upper brackets, each capable of being installed and adjusted separately. This segmentation allows each upper bracket to be processed and installed independently, reducing the complexity of ensuring accuracy across the entire structure while maintaining overall precision requirements.
Solution Approach 2:
Positioning holes and positioning protrusions are designed to enable preliminary positioning of the upper bracket relative to the lower bracket before final fastening. This preliminary action ensures accurate alignment and dimensionality during installation, reducing the need for complex adjustments while improving installation efficiency.
2Reliability
If the upper bracket needs to take into account accuracy of both left and right arc-shaped slides, then the foldable assembly can function properly, but requirements on accuracy of processing and installation dimensions of the upper bracket are relatively high
Solution Approach 1:
The upper bracket structure is segmented into multiple independent units, each responsible for forming an arc-shaped slide. This segmentation allows each unit to be processed and assembled independently, reducing the cumulative accuracy requirements that would apply to a monolithic structure while ensuring proper functionality of the foldable assembly.
Solution Approach 2:
Each upper bracket is designed with self-positioning capabilities through positioning holes and protrusions, enabling it to automatically align with the lower bracket during assembly. This self-service mechanism ensures accurate positioning without requiring complex external alignment procedures, maintaining reliability while reducing manufacturing precision requirements.
