Rolling Gate Panel Connection Profile for Simpler Vehicle Shutter Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing commercial vehicle bodies with roller shutters are complex and expensive to manufacture, making them costly and difficult to produce.
Innovation Solution
The design incorporates a tongue profile connected to the panel base via a web, with a receptacle within the tongue circle that is accessible from outside, allowing for easy connection and pivoting of panels via corresponding groove profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional roller shutter designs with multiple connecting profiles are used, then structural integrity is maintained, but manufacturing complexity and cost increase significantly
Solution Approach 1:
The connecting profile is segmented into modular components: a base body and a tongue element that can be separately manufactured and then assembled. This segmentation allows each component to be produced using simpler, more cost-effective processes while maintaining the overall structural integrity of the roller shutter system.
Solution Approach 2:
The tongue element acts as an intermediary component that simplifies the connection between panels. Instead of requiring complex integrated connecting profiles, the tongue element provides a standardized interface that reduces manufacturing complexity while ensuring reliable mechanical connection and structural stability.
2Reliability
If complex connecting profiles are used to ensure reliable panel connection, then structural integrity is improved, but assembly time and manufacturing cost increase
Solution Approach 1:
The tongue and groove profiles are pre-formed as standardized components during manufacturing. This preliminary action ensures that the connection geometry is precisely prepared in advance, allowing for rapid and reliable assembly without requiring complex on-site adjustments or operations, thereby reducing assembly time while maintaining connection reliability.
Solution Approach 2:
The tongue element design provides a reproducible connection template that can be consistently manufactured and assembled. This copying approach ensures uniform connection quality across all panels while streamlining the assembly process, as workers can repeatedly apply the same connection method without dealing with varying complex profile geometries.
