Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for installing keder tarpaulins on keder roofs require multiple personnel, are time-consuming, and cause wear and tear on the keder bead due to manual insertion, especially in spaces with limited workspace.
Innovation Solution
An assembly device with guide rollers and a connection unit that facilitates the insertion of keder beads into keder rails, allowing single-person operation and reducing wear by guiding the beads gently through rollers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual insertion method is used, then installation can be performed with simple tools, but installation time increases and wear on keder bead increases
Solution Approach 1:
The patent introduces a pulling device as an intermediary tool between the installer and the keder tarpaulin. This device includes a pulling element that engages with the keder bead and a pulling means (such as a winch or cable system) that applies controlled tensile force to draw the keder bead into the groove, replacing manual insertion methods and reducing both installation time and wear on the keder bead.
Solution Approach 2:
The installation process is segmented into distinct phases: positioning the pulling device, engaging the pulling element with the keder bead, applying tensile force to insert the keder bead into the groove, and then removing the pulling device. This segmentation allows for systematic and efficient installation while minimizing wear on the keder bead through controlled, staged application of force.
2Manufacturing precision
If two people are used for installation, then keder tarpaulin can be pulled evenly, but personnel requirements increase
Solution Approach 1:
The pulling device is designed to automatically ensure even insertion of the keder tarpaulin through its mechanical structure. The device includes guiding elements and a centrally applied pulling mechanism that naturally distributes force evenly across the keder bead, eliminating the need for multiple personnel to coordinate manual pulling while maintaining precise and even insertion.
Solution Approach 2:
The patent replaces the manual mechanical system requiring two people to pull the keder tarpaulin evenly with an automated mechanical system. The pulling device uses a winch, cable, or other mechanical means to apply controlled tensile force, substituting human coordination with an automated mechanism that ensures even insertion without requiring multiple operators.
3Device complexity
If manual pulling is used, then no special equipment is needed, but wear and tear on keder bead increases
Solution Approach 1:
The pulling element acts as an intermediary between the pulling means and the keder bead. It is designed to distribute the pulling force evenly across the keder bead surface and guide it smoothly into the groove, preventing concentrated stress and wear that occurs with manual pulling methods while still using relatively simple equipment.
Solution Approach 2:
The pulling device incorporates cushioning or protective elements that contact the keder bead before the main pulling force is applied. This preliminary cushioning protects the keder bead from sudden impacts and concentrated stress, distributing the load evenly throughout the insertion process and minimizing wear while maintaining equipment simplicity.
4Adaptability or versatility
If installation is performed in limited workspace, then adaptability to different sites is improved, but installation difficulty increases
Solution Approach 1:
The pulling device is designed with dynamic components that can adapt to different workspace configurations. The pulling means can be positioned at various locations along the keder tarpaulin, and the pulling element can be engaged at different points, allowing the system to accommodate limited or varying workspace conditions while maintaining ease of operation through flexible positioning and adjustment capabilities.
