Segmented Insect Screen Frame for Camper Van Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insect protection arrangements for mobile vehicle units, such as camper vans and caravans, are complex to mount and costly to ship due to their preassembled nature, which complicates retrofitting and transportation.
Innovation Solution
A frame arrangement with two guide rails connected by a rotary joint and an extendable insect protection screen, featuring a locking mechanism and cord brake for easy assembly and transportation, allowing the screen to be locked in any position and folded compactly for shipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a completely preassembled frame arrangement is used, then the insect protection arrangement provides complete protection functionality, but it can be shipped only with great effort and entails high costs
Solution Approach 1:
The frame arrangement is divided into separate components: guide rails, frame strips, and connecting elements. These segments can be shipped individually in a compact state and assembled at the destination, reducing shipping costs and effort while maintaining the complete protective functionality when assembled.
Solution Approach 2:
The frame components are designed to nest within each other during storage and shipping. The guide rails and frame strips can be collapsed or folded into a compact configuration that fits within the vehicle unit, eliminating the need for separate bulky packaging while preserving the complete frame structure for insect protection.
2Reliability
If a completely preassembled frame arrangement is used, then the insect protection arrangement provides complete protection functionality, but it is intricate to mount by a user or by an automotive garage
Solution Approach 1:
The frame arrangement is provided as separate modular components with standardized connecting elements. This segmentation allows for simplified assembly where each component can be independently positioned and connected, reducing mounting complexity compared to handling a single preassembled unit that requires complex installation procedures.
Solution Approach 2:
The connecting elements and mounting features are pre-configured on the individual frame components during manufacturing. This preliminary preparation of connection interfaces eliminates the need for complex field assembly operations, allowing users or garage technicians to simply connect pre-prepared components rather than assembling intricate joint mechanisms during installation.
3Ease of manufacture
If the frame arrangement is designed for easy transportation, then shipping costs are reduced, but the mounting process becomes more complex
Solution Approach 1:
The frame is segmented into transportable modules that can be shipped efficiently in a compact state. Each module contains pre-configured connecting elements that simplify the assembly process, ensuring that the segmentation required for easy transportation does not compromise mounting simplicity.
Solution Approach 2:
Connecting elements and alignment features are preliminarily configured on each frame module during manufacturing. This preliminary preparation ensures that when the modules are unpacked after shipping, they can be quickly and easily assembled without requiring complex mounting procedures, thus resolving the contradiction between transport efficiency and mounting simplicity.
