Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a magnetic jumper cable with magnets at each end is used to bypass electrical circuits, then the device can be easily operated and positioned, but it is limited to specific systems and cannot test multiple circuits simultaneously

Engineering Contradiction:
Improveease of operationVSAvoidversatility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The electrical testing device incorporates multiple output connectors (first, second, third, and fourth output connectors) that can independently connect to different circuits, enabling the single device to test multiple circuits simultaneously across various systems, thereby achieving multi-functionality and universality

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The device divides testing functions into separate output connectors, each capable of independent operation. This segmentation allows each connector to be activated independently via separate activation mechanisms, enabling simultaneous testing of multiple circuits without interference

Inventive Principle:
Principle #1Segmentation

2Device complexity

If a simple jumper cable is used for electrical testing, then the device complexity is low, but it cannot prevent system damage during testing

Engineering Contradiction:
Improvedevice complexityVSAvoidsystem protection
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The device incorporates fuses in series with each output connector before electrical connection to the system. These fuses act as protective elements that prevent excessive current from damaging the system being tested, providing beforehand cushioning against potential harm

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The fuses serve as intermediary protective components between the power source and the system being tested. They mediate the electrical connection by allowing normal current flow while blocking excessive current that could cause damage, thus protecting the system without adding significant complexity

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If multiple testing devices are used to test multiple circuits simultaneously, then each circuit can be tested independently, but the device complexity and cost increase

Engineering Contradiction:
Improvetesting efficiencyVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The device merges multiple testing functions into a single integrated unit with multiple output connectors that share a common housing and power source. This consolidation allows simultaneous testing of multiple circuits using one device rather than requiring multiple separate devices, improving productivity while maintaining manageable complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single testing device is designed with multiple output connectors that can independently test different circuits simultaneously. This multi-functional design enables one device to perform the work of multiple devices, enhancing testing efficiency and productivity

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Device complexity

If an electrical testing device lacks protective components, then the device simplicity is maintained, but system damage can occur during testing

Engineering Contradiction:
Improvedevice simplicityVSAvoidsystem damage risk
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

Fuses are incorporated into the circuit path before electrical connection to the system. These fuses provide beforehand cushioning by being positioned upstream to catch excessive current before it can reach and damage the system being tested, adding protection without significantly complicating the device

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
