Solution Overview
Problem
Existing thermal vehicles with temperature-controlled, thermally insulated cells rely on fossil fuels for temperature control, which is not suitable for applications where combustion gas emission is undesirable, such as in electromobility scenarios due to emission protection concerns.
Innovation Solution
A thermal vehicle equipped with an electrically operable temperature control device and an autonomous, self-sufficient power supply system that is independent of vehicle resources and emission-free, allowing for continuous temperature control without external electrical energy, featuring a rechargeable battery arrangement or fuel cell for power, and a thermally insulating design with a compact and fire-retardant structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If a thermal vehicle uses a conventional temperature control device operated with fossil fuels, then the temperature control function is achieved, but combustion gas emissions are generated which are undesirable in electromobility applications
Solution Approach 1:
The patent replaces the mechanical/internal combustion engine system with an electric motor system for driving the temperature control device. The refrigeration compressor is driven by an electric motor instead of a combustion engine, eliminating combustion gas emissions while maintaining the temperature control function. This substitution aligns with electromobility requirements.
Solution Approach 2:
The patent introduces an intermediary energy storage system (accumulator/battery) between the electric motor and the refrigeration compressor. This accumulator stores electrical energy and provides it to the electric motor, enabling the temperature control device to operate independently of the vehicle's main power supply and without requiring a combustion engine.
2Object-generated harmful factors
If the temperature control device is electrically operated with an autonomous power supply, then emission-free operation is achieved, but the device complexity increases due to additional power supply components
Solution Approach 1:
The patent designs the autonomous power supply system (accumulator) to serve multiple functions: it provides electrical energy to the electric motor for driving the refrigeration compressor, and can also supply power to other vehicle systems. This multi-functionality reduces the need for separate dedicated power supply systems, thereby managing complexity.
Solution Approach 2:
The patent combines the autonomous power supply system for the temperature control device with the vehicle's existing electrical system components. The accumulator and electric motor are integrated into the vehicle's overall electrical architecture, sharing control systems and infrastructure, which reduces the net increase in device complexity.
3Duration of action of moving object
If the accumulator capacity is designed to maintain operation for at least one day without significant solar radiation, then autonomous operation is ensured, but the weight and volume of the power supply system increase
Solution Approach 1:
The patent implements a dynamic power supply architecture where the accumulator capacity can be flexibly adjusted or supplemented based on operating conditions. The system can adapt its power delivery strategy, drawing from the accumulator when needed and potentially integrating with external power sources (like solar radiation when available) to reduce the required accumulator size for one-day autonomy.
