Tubular Material Fixation Device With Guide Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tubular material fixation devices face challenges in providing consistent clamping force and wrapping power due to unequal gaps between C-shaped caps and locating blocks, leading to damage and reduced effectiveness over time.
Innovation Solution
A tubular material fixation device featuring a locating block with a clamping groove and guide surface portions on its sidewalls, paired with a clamping plate having a curved portion and ribs that guide the fastening units to ensure equal pressure distribution and enhanced clamping force, using fastening units like screws or quick release screw rods to secure the tubular material between the clamping groove and curved portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the C-shaped cap and locating block are made with a gap to provide clamping force, then the clamping force is improved, but the gaps become unequal when screws are threaded at different depths, lowering the wrapping power
Solution Approach 1:
The guide surface portions are pre-formed on the sidewalls of the locating block before assembly. These guide surfaces preliminarily establish the correct positioning and equal gap distribution between the C-shaped cap and locating block, ensuring that when screws are fastened, the clamping force is evenly distributed across both ends without requiring precise manual adjustment of screw depths.
2Force
If the C-shaped cap is forced to give pressure to the tubular material against the locating block, then the clamping function is improved, but the screws and screw holes are easily damaged due to tension in the same direction
Solution Approach 1:
The guide surface portions preliminarily position the C-shaped cap and locating block to ensure proper alignment and distribute the clamping force evenly. This preliminary positioning prevents excessive concentrated forces on the screws and screw holes during fastening, reducing the risk of damage while maintaining effective clamping function.
3Reliability
If the C-shaped cap is used to hold down the tubular material, then the fixation effect is improved, but the C-shaped cap wears quickly with use, lowering its clamping function
Solution Approach 1:
The guide surface portions are pre-formed to establish correct positioning and force distribution. This preliminary structural arrangement ensures that the clamping force is evenly distributed across the contact surfaces, preventing concentrated wear on the C-shaped cap and thereby extending its service life while maintaining reliable fixation effect throughout the operational period.

AI summary
A tubular material fixation device includes a locating block, which has a clamping groove and two sidewalls disposed at two sides of the clamping groove and defining a respective guide surface portion, a clamping plate, which has a curved portion corresponding to the clamping groove, two side panels respectively extending from two sides of the curved portion, and two ribs respectively extending from the side panels corresponding to the guide surface portions of the locating block, and fastening units for fastening the side panels to the sidewalls to force the ribs along the guide surface portions and to further move the side panels of the clamping plate toward the locating block so as to lock a tubular material in between the clamping groove and the curved portion.
