Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hollow hinges experience reduced torque and issues of wavering and friction due to abrasion of internal bump structures over time, affecting their durability and assembly reliability.
Innovation Solution
A hollow hinge design featuring a first and second hollow component with concave and receiving portions, respectively, and support assemblies comprising elastic and spherical elements that reduce friction and provide enhanced support, thereby stabilizing the components during rotation and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If bump structures are used to control torque, then torque control is achieved, but friction increases and durability decreases due to abrasion over time
Solution Approach 1:
The patent introduces a support assembly as an intermediary component between the bump structure and the rotating component. This support assembly includes a support body with a bearing that mediates the contact interaction, reducing direct friction and wear between the bump structure and rotating parts while maintaining torque control functionality.
Solution Approach 2:
The patent replaces the direct mechanical contact of bump structures with a bearing-based support system. The bearing substitutes the simple mechanical bump contact with a more sophisticated rolling contact mechanism, reducing friction and improving durability while maintaining the torque control function.
2Strength
If bump structures are used for torque control, then initial support is provided, but wavering and friction occur after extended use
Solution Approach 1:
The support assembly acts as an intermediary that maintains the support function while eliminating the wavering and friction problems. The bearing within the support body provides smooth rotation while the support structure maintains the necessary strength for torque control.
3Device complexity
If conventional hollow hinge structure is used, then assembly is simple, but assembly reliability decreases due to component wavering
Solution Approach 1:
The patent divides the hollow hinge into segmented components including the first hollow component, second hollow component, and separate support assemblies. This segmentation allows each component to be optimized independently while maintaining overall assembly simplicity and improving reliability through the specialized support structures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces friction and prolongs the durability of the hollow hinge, improving assembly reliability and production yield by providing a strengthened support structure that minimizes wavering and leaning during assembly and use.
Implementation Method 1
support assemblies (30) respectively contained in the receiving portions (211), and end portions (321) of the support assemblies (30) continuously butt against the first hollow component (10) through a force
Implementation Method 2
the friction between components is reduced by the support assemblies provided

AI summary
A hollow hinge includes a first hollow component, a second hollow component and a plurality of support assemblies. The first hollow component has a first surface and a second surface opposite to the first surface, and a plurality of concave portions are disposed on the second surface. The second hollow component is disposed on the second surface of the first hollow component and a plurality of receiving portions corresponding to the concave portions are disposed on the second hollow component. The support assemblies are respectively contained in the receiving portions and continuously butt against the first hollow component through a force. The hollow hinge avoids friction between components and strengthens support, thereby prolonging durability and improving assembly and production yield rate.
