Variable-Width Spray Vehicle for Epoxy Adhesive Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spray vehicles for applying two-component epoxy adhesives are inflexible and require multiple units for different road widths, making them inefficient and difficult to use for applications requiring fast and accurate coverage over varying surfaces.
Innovation Solution
A spray vehicle with a variable-width spray body and adjustable nozzles, equipped with a compressor for high-pressure atomization and a controller for automated component mixing and application, allowing for continuous application of epoxy adhesive over different road widths without interruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-width spray vehicle is used, then the device structure is simple, but it cannot adapt to different road widths and requires multiple vehicles
Solution Approach 1:
The spray body is designed with variable width capability, allowing it to dynamically adjust its spraying width to match different road widths. This dynamic adaptation eliminates the need for multiple fixed-width vehicles while maintaining operational simplicity through a single adjustable mechanism.
Solution Approach 2:
The spray vehicle is designed as a universal device that can handle multiple road width specifications through its adjustable spray body. This multi-functional capability allows one vehicle to perform the work of several fixed-width vehicles, improving adaptability without proportionally increasing complexity.
2Adaptability or versatility
If the spray body width is changed during application, then flexibility is improved, but the application process becomes more complex and may require stopping
Solution Approach 1:
The spray body incorporates dynamic width adjustment capability that allows real-time modification of spray width during movement. This dynamic system enables width changes without requiring the vehicle to stop, maintaining continuous application productivity while providing operational flexibility.
Solution Approach 2:
The spray vehicle maintains continuous application operation by enabling width adjustments during movement rather than requiring stops. The useful action of applying epoxy adhesive continues uninterrupted while the spray body adapts its width, ensuring both flexibility and productivity are maintained simultaneously.
3Manufacturing precision
If multiple spray vehicles are provided for different widths, then each road width can be optimized, but the cost and number of vehicles increases
Solution Approach 1:
A single spray vehicle is designed with universal capability to handle multiple road width specifications through its adjustable spray body. This multi-functional design allows one vehicle to replace multiple specialized vehicles, reducing the total quantity of vehicles needed while maintaining the precision required for different road widths through controlled adjustment mechanisms.
