Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual testing is used to test charging devices, then testing can be performed with simple equipment, but the testing process is cumbersome, time-consuming and laborious

Engineering Contradiction:
Improvetesting efficiencyVSAvoidtest system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The test board automatically executes test commands and collects test results without requiring manual intervention. The control module on the test board receives commands from the upper computer, automatically controls the charging device under test, and collects test data, enabling the system to serve itself and eliminate manual testing operations.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical testing operations with an automated electronic control system. The upper computer sends digital commands through communication modules to control the charging device, and electronic sensors automatically collect test data, substituting the mechanical manual testing process with an automated electro-mechanical system.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Loss of time

If manual testing is used, then equipment complexity is low, but the time required to complete tests is long

Engineering Contradiction:
Improvetest durationVSAvoidtest board complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The test board pre-configures multiple test items and parameters before actual testing. The upper computer can prepare test sequences and command sets in advance, and the test board stores test configurations, enabling rapid execution of comprehensive tests without manual setup for each test item.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The automated test system continuously executes test commands and collects data without interruption. The control module maintains continuous communication with the charging device under test, continuously monitoring parameters and executing test sequences, eliminating the gaps and delays inherent in manual testing operations.

Inventive Principle:
Principle #20Continuity of useful action
