Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If testing probes are used for long-term testing, then testing experience and reliability improve, but dust accumulates on probe surfaces affecting contact stability
Solution Approach 1:
The testing probe is equipped with a gas spray cleaning mechanism that automatically cleans the probe surface during testing operations. The gas spray device directs cleaned gas onto the probe surface to remove dust and impurities, enabling the probe to maintain its own cleanliness without external intervention and ensuring continuous reliable testing.
2Adaptability or versatility
If manual or mechanical transfer mechanisms are added to move smart electric meters between testing positions, then testing flexibility improves, but device complexity and costs increase
Solution Approach 1:
The testing probe is designed with multi-functionality, serving both as a testing device and a positioning device. The probe can test smart electric meters at multiple positions (first position and second position) without requiring separate transfer mechanisms. The gas spray cleaning function is integrated into the same probe structure, eliminating the need for additional cleaning equipment and reducing overall system complexity.
3Measurement precision
If testing probes are replaced when damaged or dirty, then testing accuracy is maintained, but testing downtime increases
Solution Approach 1:
The gas spray cleaning mechanism enables continuous testing operations by automatically cleaning the probe surface during or between testing cycles. This eliminates the need to stop testing for probe cleaning or replacement, maintaining continuous useful action. The probe can be quickly reset to a clean state without interrupting the overall testing workflow, ensuring both accuracy and efficiency.
4Measurement precision
If additional cleaning equipment is added to remove dust from testing probes, then testing accuracy improves, but device complexity increases
Solution Approach 1:
The cleaning function is merged with the testing probe structure itself. The gas spray device is integrated into the probe assembly, combining testing and cleaning functions in a single integrated unit. This eliminates the need for separate cleaning equipment and reduces overall device complexity while maintaining testing accuracy through effective dust removal.
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
Facilitates uninterrupted testing by automatically switching between testing probes, reducing downtime and maintenance complexity, and maintaining testing accuracy without manual adjustments.
Implementation Method 1
The testing equipment generates gas to be discharged into an air jet ring through components, and the gas is sprayed to the testing probe through a flat opening of the air jet ring to clean the surface of the testing probe and prevent the dust on the surface of the test probe from affecting the test accuracy.
Implementation Method 2
first sliding grooves are defined on a front of the installation base and mirror-symmetrically arranged with a center point of the installation base, the first sliding grooves are designed to be inclined
Implementation Method 3
a pulling rope and inclined sliding grooves

AI summary
An intelligent electric meter digital manufacturing platform based on intelligent manufacturing includes: an electric push rod fixedly disposed in a frame and a testing machine disposed on the electric push rod. The testing machine includes a box fixedly disposed on a telescopic shaft of the electric push rod and a testing component disposed in the box. A first pulley drives two ends of a pulling rope to move from a middle end of a side wall of the pulling rope through driving of a servo motor. This makes an end of the pulling rope pull a testing probe to move upwards, the other end of the pulling rope pull the other testing probe to move downwards, allowing it move to a bottom of the box. This design avoids affecting testing efficiency due to the need to replace or maintain the testing probes, facilitating subsequent testing of an intelligent electric meter.
