Rotary Shaft Link Support Structure for Smooth Stable Pivoting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotary shaft structures in electronic devices suffer from poor operational smoothness and limited rotational freedom due to complex connections lacking a locating mechanism, causing the pivotally connected sections to loosen and swing, rather than smoothly rotate.
Innovation Solution
A uniform distribution support structure for rotary shaft link assemblies, featuring connection members with hollow sections and spacer shaft rods, along with a flexible support member and guide faces, which allows the connection members and spacer shaft rods to pivotally rotate and displace stably at fixed intervals, ensuring smooth operation by abutting guide faces and arched surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple rotary shafts are disposed on two sides of pivoted sections to improve supporting strength, then the strength of supporting structure is improved, but the coordination between rotary shafts becomes不理想 and rotational freedom is limited
Solution Approach 1:
The invention divides the connection members into multiple segments (first connection member, second connection member, third connection member) that can independently pivot relative to each other. Each segment can rotate freely around its own pivot point, enabling multi-directional movement and improving rotational freedom while maintaining supporting strength through the distributed segment structure.
Solution Approach 2:
The invention transforms the static fixed-position rotary shaft arrangement into a dynamic system where connection members can adaptively change their relative positions. The pivotable connection members allow the structure to dynamically adjust its configuration during operation, enabling smooth coordination between multiple rotation points without limiting rotational freedom.
2Strength
If complicated connection structures are used to connect components, then the supporting strength is improved, but the pivotally connected sections loosen and swing and cannot rotate smoothly
Solution Approach 1:
The invention extracts the locating function from the complicated connection structure and implements it through simple positioning holes and positioning pins. This separation allows the connection structure to maintain strength while the dedicated positioning elements ensure precise component alignment, preventing loosening and swinging during rotation.
Solution Approach 2:
The invention introduces positioning holes and positioning pins as intermediary elements between connection members. These intermediaries provide precise locating functionality, ensuring that pivotally connected sections maintain accurate relative positions while rotating, thereby preventing loosening and swinging without requiring complicated connection structures.
3Device complexity
If no locating mechanism is provided for components, then the device complexity is reduced, but the pivotally connected sections loosen and swing
Solution Approach 1:
The invention implements self-locating functionality through positioning holes and positioning pins that automatically align and locate connection members during assembly. This self-service locating mechanism maintains component positioning stability without requiring complex external locating systems, thereby keeping the device complexity low while ensuring stable component arrangement.
