Corner Hollow Body Fastening Assembly for Precise Room Cell Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for cuboid-shaped room cells, such as containers, lack precise positioning and secure attachment of connecting parts like roofs, platforms, or staircases, leading to potential misalignment and assembly challenges.
Innovation Solution
A fastening device comprising an elongated fastening body with internal threading and a clamping body, allowing secure and precise attachment to the corner connecting hollow body, featuring an elongated opening for easy assembly and disassembly, ensuring the fastening body remains locked in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing fastening systems are used for cuboid-shaped room cells, then assembly can be performed, but precise positioning and secure attachment of connecting parts cannot be achieved
Solution Approach 1:
The fastening device is divided into separate functional components: a fastening body with threading for secure attachment, a clamping body for positioning, and an elongated opening for tool-free assembly. This segmentation allows each component to optimize its specific function while working together as a integrated system.
Solution Approach 2:
The clamping body acts as an intermediary element between the fastening body and the connecting part (roof, platform, staircase). It provides the clamping force necessary for precise positioning while allowing the fastening body to remain locked in place through its internal threading mechanism.
2Reliability
If secure fastening is achieved through complex fastening systems, then attachment security is improved, but assembly complexity and tool requirements increase
Solution Approach 1:
The fastening device enables tool-free assembly through its elongated opening design. The clamping body can be manually inserted and positioned through the opening, and the internal threading of the fastening body automatically secures the connection without requiring additional tools, making the system self-sufficient for assembly operations.
Solution Approach 2:
Instead of requiring tools to tighten and secure fastening elements from the outside, the design allows the fastening body to be inserted through the elongated opening and secured from the inside. The clamping body engages with the fastening body in reverse of traditional fastening systems, enabling simple manual assembly while maintaining secure attachment.
