Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotary shaft structures in electronic devices lack a shielding mechanism for their connection sections, leading to exposure and issues like powder and oil leakage, which affect the product's appearance and quality.
Innovation Solution
A rotary shaft link assembly with multiple connection members having hollow sections and a flexible shield plate that securely attaches to the shaft assembly, providing comprehensive shielding and aesthetic enhancement by absorbing surface length changes during rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional rotary shaft structures are used without shielding mechanism, then the structure is simple and easy to manufacture, but the connection sections are exposed causing powder and oil leakage which affects appearance and quality
Solution Approach 1:
The shield plate is nested within the hollow section of the connection member, creating a protective enclosure around the rotary shaft assembly. The shield plate fits inside the hollow space, forming a nested structure that prevents leakage while maintaining compact design
Solution Approach 2:
The shield plate is designed as a flexible component that can bend and deform to accommodate the rotational movement of the rotary shaft assembly. This flexible shielding approach prevents powder and oil leakage while allowing the necessary mechanical motion
2Object-affected harmful factors
If shield plate is added to shield the rotary shaft assembly, then powder and oil leakage is prevented and appearance is improved, but the device complexity increases
Solution Approach 1:
The shield plate serves multiple functions: it prevents powder and oil leakage, improves appearance, and accommodates rotational movement through its flexibility. This multi-functionality reduces the need for additional separate components
Solution Approach 2:
The shield plate is nested within the existing hollow section of the connection member, utilizing the available space efficiently. This nested approach adds the shielding function without requiring external additions that would increase overall complexity
3Ease of operation
If multiple connection members are arranged side-by-side, then the synchronous rotational assembly can be connected between supports, but the connection sections are directly exposed to outer side without shielding
Solution Approach 1:
The shield plate is nested within the hollow section of each connection member, providing individual protection for each connection section while maintaining the side-by-side arrangement of multiple connection members for synchronous rotation

AI summary
A rotary shaft link assembly shield structure is connected between a first support and a second support of two articles. The rotary shaft link assembly structure has a rotary shaft assembly, at least one flexible shield plate and at least one synchronous rotational assembly. The rotary shaft assembly has multiple connection members. Each connection member is correspondingly formed with at least one hollow section. The synchronous rotational assembly passes through the hollow sections of the connection members to respectively connect with the first and second supports. The flexible shield plate also passes through the hollow sections of the respective connection members. A middle section of the flexible shield plate is bent in reverse direction and two sides of the flexible shield plate respectively shield two surfaces of the synchronous rotational assembly.
