Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chassis systems for amphibious remote control vehicles face instability and high energy consumption due to damage to inflatable floating devices or excessive water resistance from grid box structures, which hinder stable water travel and increase energy consumption.
Innovation Solution
A chassis system comprising a vehicle chassis with joint portions and a hull form chassis with inclined surfaces, where the hull form chassis is fixedly attached to the vehicle chassis using fixing members, reducing water resistance and allowing for easy replacement, and made of plastic to minimize weight and energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple grid boxes are connected to provide buoyancy, then the vehicle can travel on water, but excessive water resistance increases energy consumption
Solution Approach 1:
The hull form chassis features a streamlined, curved V-shaped cross-section design that reduces water resistance compared to boxy grid structures. The smooth contours allow water to flow more easily around the vehicle, decreasing drag and energy consumption while maintaining adequate buoyancy.
Solution Approach 2:
The design changes the geometric parameters of the buoyancy structure from multiple separate boxes to a single integrated hull form with optimized dimensions. The V-shaped cross-section and streamlined length-to-width ratio are specifically tuned to minimize water resistance while providing sufficient displacement for buoyancy.
2Reliability
If multiple grid boxes with connection structures are used, then buoyancy is provided, but the complex connection structure increases device complexity
Solution Approach 1:
Multiple separate grid boxes are merged into a single integrated hull form chassis that provides the same buoyancy function. This consolidation eliminates the need for multiple connection structures between separate boxes, significantly reducing device complexity while maintaining buoyancy support.
Solution Approach 2:
The hull form chassis serves multiple functions simultaneously: it provides buoyancy, reduces water resistance, and simplifies the overall structure. This multi-functional design replaces the need for separate buoyancy boxes and connection structures, reducing complexity while maintaining or improving performance.
