Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional rectification and filtration processes are used to convert AC to DC, then voltage conversion is achieved, but power loss and heat generation increase
Solution Approach 1:
The patent extracts and eliminates the rectification and filtration components from the conventional AC-to-DC conversion system. By removing these components that cause power loss and heat generation, the system directly charges the chemical storage device using AC current, achieving significant power efficiency improvement while eliminating the associated energy losses.
2Ease of manufacture
If conventional rectification systems are used, then DC current is produced, but additional parts and costs increase
Solution Approach 1:
The patent removes the rectification and filtration components from the system, significantly reducing component count and manufacturing cost. The simplified system uses only essential components (AC source, gate controller, gate, and chemical storage device) to achieve the charging function, eliminating the need for expensive rectifier bridges and filter circuits.
Solution Approach 2:
The gate controller and gate mechanism serve multiple functions: they control current flow timing, regulate charging rate, and protect the chemical storage device from overcharging. This multi-functionality replaces what would traditionally require separate rectification and filtration components, reducing overall system complexity.
3Productivity
If conventional charging systems are used, then chemical storage devices are charged, but charging speed is slow
Solution Approach 1:
The patent employs periodic switching of the gate controlled by the gate controller to charge the chemical storage device. By opening and closing the gate at specific intervals synchronized with AC voltage cycles, the system achieves controlled high-rate charging. This periodic action allows the device to accept charge ten times faster than conventional systems while maintaining safety through precise timing control.
4Reliability
If conventional rectification is used, then voltage conversion occurs, but heat generation increases creating safety risks
Solution Approach 1:
The patent eliminates the primary heat-generating components (rectifiers and filters) from the system. By charging the chemical storage device directly from AC current without these components, the system removes the main sources of heat generation, significantly improving safety and reducing thermal management requirements.
Solution Approach 2:
The patent converts the potentially harmful AC current (which could cause overheating through conventional rectification) into a beneficial charging source. By using the gate controller to manage AC current flow directly to the chemical storage device, the system transforms what would be a heat-generating process into an efficient, safe charging method that utilizes the full AC power without conversion losses.
Data Source
AI summary
A system is provided to allow for charging of a chemical storage device without a rectifier. A gate is used in conjunction with a gate controller. The gate controller monitors input voltage and opens the gate when voltage crosses a zero crossing in a first direction. The gate monitor then closes the gate when the voltage crosses a zero crossing in a second direction. This increases the chances that the output power will have voltage in a single direction. This output power is then fed to a chemical storage device, where it can be stored and used by one or more electronic devices.
