Vehicle Canopy Three-Panel Join With Offset Sealing Lips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle canopies face challenges in sealing off the interior, with gaps at three-panel joins allowing water and dust ingress, and existing solutions like applying sealant post-assembly are inconvenient and costly.
Innovation Solution
A panel joining arrangement featuring longitudinally offset and transversely overlapping lip portions on side panels, a mating third lip portion on the roof panel, and optional sealing foam tape between these surfaces to ensure flush and secure connections at three-panel joins, reducing gaps and leaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional panel joining is used at three-panel joins, then assembly is simple, but gaps form allowing water and dust ingress
Solution Approach 1:
The lip portions are nested within recesses of adjacent panels, with each lip fitting into a corresponding recess to create an interlocking joint. The first lip portion of one panel nests into a recess of another panel, while the second lip portion nests into a recess of a third panel, forming a sealed three-panel join without gaps.
Solution Approach 2:
The solution transitions from simple planar panel edges to three-dimensional lip portions with multiple dimensions. The lips have longitudinal offset and transverse overlap, creating a multi-dimensional interlocking structure that prevents water and dust ingress while maintaining assembly feasibility.
2Reliability
If sealant is applied at three-panel joins after assembly, then sealing performance improves, but assembly time and cost increase
Solution Approach 1:
The sealing function is built into the panel structure itself through the lip and recess configuration before assembly occurs. The interlocking lip portions create a flush, gap-free joint that inherently prevents water and dust ingress, eliminating the need for post-assembly sealant application and reducing assembly time.
Solution Approach 2:
The panel joining arrangement is self-sealing through its geometric design. The longitudinally offset and transversely overlapping lip portions automatically create a weather-tight joint when assembled, without requiring additional sealing materials or procedures. The structure serves its own sealing function.

AI summary
The invention relates to a panel joining arrangement for a vehicle canopy. The vehicle canopy includes at least one three panel join where a side panel, roof panel and end panel of the vehicle canopy meet. The panel joining arrangement comprises first and second lip portions formed in the side panel of the vehicle canopy and a third lip portion formed in the roof panel. The first and second lip portions are longitudinally offset and transversely overlapping in relation to a length of the side panel. The third lip portion is configured to mate with the second lip portion at the three panel join of the vehicle canopy such that the third lip portion is located adjacent to and substantially flush with the first lip portion.
