Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing costs and challenges of transporting cargo, particularly on unpredictable ice roads and in areas requiring skilled drivers, due to rising fuel costs and environmental changes, necessitate a more efficient and safer solution for long-distance cargo transport across varied terrain.
Innovation Solution
An autonomous self-propelled trailer with an elongated chassis, powered by petroleum, electric, or solar energy, equipped with steerable wheels and an autonomous controller, capable of navigating without human assistance, and designed to operate on ice roads, off-road, and regular roads, with optional pontoons for flotation, allowing for platooning and efficient cargo movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If autonomous control systems are implemented, then the need for skilled drivers is reduced and operational safety is improved, but device complexity increases
Solution Approach 1:
The vehicle is equipped with autonomous control capabilities including sensors, processors, and actuation systems that enable it to navigate, steer, and operate without human intervention. The system autonomously detects environmental conditions, plans routes, controls steering and propulsion, and monitors vehicle status, effectively making the vehicle self-service in terms of navigation and operation.
2Use of energy by moving object
If energy-efficient propulsion systems are used, then fuel consumption is reduced by half, but power density and acceleration capability may be compromised
Solution Approach 1:
The vehicle employs electric motors that can dynamically adjust their operational parameters including power output, torque, and efficiency based on real-time conditions. The electric propulsion system optimizes energy consumption while maintaining adequate acceleration capability through electronic control of motor parameters and regenerative braking that recovers energy during deceleration.
3Productivity
If the vehicle is designed for 24/7 continuous operation, then productivity increases, but reliability requirements and maintenance needs increase
Solution Approach 1:
The autonomous vehicle incorporates comprehensive sensor arrays and monitoring systems that continuously feedback vehicle status, environmental conditions, and system performance data to control algorithms. This enables real-time adjustments, predictive maintenance scheduling, and automatic detection of potential failures, allowing the vehicle to operate reliably 24/7 with minimal human intervention.
4Reliability
If pontoons or floatation devices are added for ice road safety, then safety is improved in case of ice breakdown, but device complexity and weight increase
Solution Approach 1:
The vehicle incorporates deployable pontoon systems that can be dynamically extended or retracted based on detected ice conditions. Sensors monitor ice thickness and structural integrity, and when potential ice breakdown is detected, the pontoons automatically deploy to provide buoyancy support, allowing the vehicle to transition from land-based to water-based operation without permanent structural modifications.
Data Source
AI summary
A transport vehicle has a front chassis section and a rear chassis section supported on respective steerable bogie frames with longitudinal and lateral suspension stabilizers. A recessed central chassis section between the front and rear sections supports a power source for powering drive motors on the bogie frames. A load supporting surface spans a full length of the vehicle over the front and rear bogie frames and the recessed power source therebetween. A controller autonomously controls the drive motors and the steering of the bogies to autonomously drive and steer the transport vehicle along a prescribed transport route stored on the autonomous controller, while supporting cargo ton the load supporting surface that can span the length of the vehicle or longer. Locating the wheels and power source within the footprint of the load supporting surface, allows the overall size of the vehicle to be minimized to improve transport economy.
