Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional energy meters are limited by their predetermined dielectric strength, restricting them to measuring only voltages up to a defined upper voltage limit, making them unsuitable for environments requiring higher dielectric strength.
Innovation Solution
An adapter with a voltage converter is introduced, which connects to the energy meter's terminals and converts higher applied voltages to a lower voltage, allowing the energy meter to measure higher voltages while maintaining a compact design, and increasing the dielectric strength of the energy measurement device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the energy meter is designed with a predetermined dielectric strength to comply with standards, then the device meets safety requirements, but it cannot measure voltages beyond a defined upper voltage limit
Solution Approach 1:
The patent introduces an adapter as an intermediary device between the high-voltage power network and the energy meter. The adapter contains a voltage converter that transforms the high voltage from the power network into a lower voltage suitable for the energy meter's predetermined dielectric strength, enabling the meter to measure higher voltages without compromising its safety standards.
Solution Approach 2:
The voltage converter in the adapter changes the voltage parameter from a high first voltage to a lower second voltage through electromagnetic transformation. This parameter transformation allows the energy meter to operate within its safe dielectric limits while measuring voltages that would otherwise exceed its design specifications.
2Reliability
If the adapter uses a voltage converter to handle higher voltages, then the dielectric strength is increased, but the physical dimensions and volume of the device increase
Solution Approach 1:
The energy meter is mechanically received and nested within the adapter housing. The adapter's receiving region is designed to accommodate the energy meter in a detachable manner, creating a compact nested structure where the meter fits inside the adapter, thereby minimizing the overall volume of the combined device.
Solution Approach 2:
The patent increases the distance between electrical terminals in the adapter rather than expanding the overall device volume uniformly. By strategically positioning terminals at greater distances apart within the adapter structure, the design achieves higher dielectric strength without proportionally increasing the total device volume.
