Protective Roof Rail Holder With Locking Pins for Precise Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temporary protective roof systems face challenges in efficient assembly and disassembly, user-friendliness, and proper angular positioning of rail holders on cylindrical support structures, leading to issues like offset and inclined keder rails, which cause mounting problems and potential water collection or noise due to flapping tarpaulins.
Innovation Solution
A temporary protective roof system with moveable locking pins in the rail holder for detachable engagement with roof support beams, allowing for quick and reliable angular positioning, tool-free assembly, and simplified handling, ensuring the rail holder remains stable over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional clamp with threaded member is used to fasten the rail holder to the support beam, then the connection can be secured, but the assembly process becomes time-consuming and requires tools
Solution Approach 1:
The fastening mechanism is segmented into modular components: a rail holder assembly that can be detached and reattached multiple times. The locking mechanism uses separate locking elements (pins or clips) that can be independently engaged with the support beam, allowing quick tool-free assembly while maintaining secure connection
Solution Approach 2:
The fastening system transitions from a static threaded clamp to a dynamic locking mechanism that can be quickly engaged and disengaged. The locking elements are designed to snap into place or be quickly secured without requiring rotational movement or tools, enabling rapid assembly and disassembly operations
2Ease of operation
If the rail holder is manually positioned on the support beam, then installation is simple, but angular positioning accuracy deteriorates causing offset and inclined keder rails
Solution Approach 1:
The rail holder incorporates self-positioning features such as alignment guides, tapered surfaces, or keyed interfaces that automatically orient the holder at the correct angle relative to the support beam. The design self-corrects positioning errors during installation, eliminating the need for complex measurement and adjustment procedures while maintaining high angular precision
Solution Approach 2:
The manual angular positioning process is replaced by a mechanical guidance system built into the rail holder and support beam interface. The geometry of the mating surfaces or the presence of alignment features provides passive mechanical guidance that ensures accurate angular positioning without requiring operator skill or measurement tools
3Productivity
If the rail holder is incorrectly positioned, then assembly is faster, but the tarpaulin mounting quality deteriorates causing pockets and flapping
Solution Approach 1:
The rail holder is pre-configured with built-in alignment features and positioning guides that ensure correct angular orientation before the tarpaulin is attached. The support beam interface includes reference surfaces or mechanical stops that pre-establish the proper geometry, so that when the rail holder is quickly installed, the tarpaulin automatically receives accurate positioning, preventing pockets and flapping without sacrificing assembly speed
