Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If lithium-ion batteries are used to provide drive energy, then the motor vehicle can operate with local absence of emissions, but the energy density and range are limited compared to solid-gas batteries
Solution Approach 1:
The charging system is segmented into two independent supply units: an energy supply unit for electrical current and a gas supply unit for gas. This segmentation allows the system to address the specific requirements of solid-gas batteries (needing both energy and gas) without the complexity of integrated systems, enabling simpler implementation while achieving higher energy density
Solution Approach 2:
The charging device is designed with multi-functionality to serve dual purposes: supplying electrical current through the energy supply unit and supplying gas through the gas supply unit. This universal charging system can handle both the energy and gas requirements of solid-gas batteries through a single integrated charging device, resolving the complexity issue while enabling higher energy density operation
2Duration of action of moving object
If solid-gas batteries are used to increase energy density and range, then the motor vehicle can achieve extended operation, but special charging devices are required that provide both fuel and electrical current
Solution Approach 1:
The charging device is divided into separate functional modules: an energy supply unit connected via an energy supply line and a gas supply unit connected via a gas supply line. This segmentation allows each unit to be optimized independently for its specific function while maintaining overall system simplicity, enabling extended range operation without excessive charging device complexity
Solution Approach 2:
The patent introduces supply connections as intermediary components that facilitate the transfer of both electrical current and gas from the charging device to the motor vehicle. These intermediary connection elements simplify the interface between the dual-function charging device and the vehicle, making the system easier to implement while supporting extended range through solid-gas battery operation
3Productivity
If a charging device supplies both electrical current and gas simultaneously, then charging efficiency is improved, but the system requires multiple supply units and connections
Solution Approach 1:
The energy supply unit and gas supply unit are merged into a single integrated charging device with common control and housing. This merging allows simultaneous supply of both electrical current and gas through separate but coordinated supply lines, improving charging efficiency while avoiding the complexity of completely separate systems through unified design and control
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient charging and operation of solid-gas batteries with increased energy density and range, weight reduction in vehicles, and extended battery life by providing direct current and purified gas, while allowing for gas type exchange and recycling.
Implementation Method 1
The gas supply unit includes a compressor which is designed to compress gas for the solid-gas battery and supply the compressed gas to the motor vehicle
Implementation Method 2
If, for example, an external voltage potential is applied to the solid-gas battery, which voltage potential exceeds the potential during the discharging of the solid-gas battery, the described process is reversed, and the solid-gas battery is charged. In this case, the electrochemical bonds between the ions of the solid anode and the atoms or molecules of the supplied gas are severed again.
