Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous work vehicles lack a reliable method for smooth transportation to multiple work sites, especially when owned by contractor firms, and do not account for battery charging or fire safety during transport.
Innovation Solution
An accommodation device with multiple cases mounted on a transporter vehicle, featuring a supporting section, actuator, electric generator, detection section for battery power, power storage, temperature sensor, gas cylinder, and valve control for fire extinguishing, and air blowing or arm collection mechanisms to facilitate smooth transport and autonomous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple work vehicles are transported to multiple work sites, then transportation efficiency is improved, but the number of attendants required increases
Solution Approach 1:
The accommodation device enables self-service operation through automated functions: the actuator automatically moves accommodation cases along the path, the detection section monitors battery power levels, and the power storage section charges batteries automatically. This eliminates the need for multiple attendants to manually handle work vehicles during transportation and preparation.
Solution Approach 2:
The system performs preliminary actions before work vehicles are needed at the destination: batteries are charged in advance by the power storage section using the electric generator, and work vehicles are positioned in accommodation cases beforehand. This preparation during transportation eliminates the need for manual intervention at the destination.
2Productivity
If work vehicles are transported without battery charging capability, then transportation is simpler, but work operations are interrupted due to battery depletion
Solution Approach 1:
The battery charging function is merged with the transportation system. The power storage section and electric generator are integrated into the accommodation device, allowing batteries to be charged automatically during the transportation process without requiring separate charging infrastructure at work sites.
Solution Approach 2:
The charging action continues throughout the transportation process. The detection section continuously monitors battery power levels, and the power storage section automatically charges batteries when power levels are insufficient, ensuring work vehicles are always ready for operation upon arrival at any destination.
3Reliability
If fire safety measures are not implemented, then the device is simpler, but fire damage can occur during transportation
Solution Approach 1:
Fire safety measures are prepared in advance: the gas cylinder is pre-filled with fire extinguishing gas, and the temperature sensor is positioned to detect rising temperatures before fire occurs. When the temperature sensor detects excessive heat, the valve control section automatically opens the valve to release extinguishing gas, preventing fire damage without requiring manual intervention.
4Quantity of substance
If multiple accommodation cases are used to transport multiple work vehicles, then transportation capacity is improved, but the supporting structure becomes more complex
Solution Approach 1:
The transportation system is segmented into multiple independent accommodation cases, each capable of holding one work vehicle. The supporting section provides structured support for each case along a defined path, allowing the system to scale capacity by adding cases without fundamentally redesigning the entire support structure.
