Solution Overview

Problem

Existing CAN system testing methods are costly and time-consuming due to the complexity of hardware and the need for complete system assembly before testing can begin, leading to delays and increased costs if issues are found late in the assembly phase.

Innovation Solution

A system utilizing an interconnection terminal box that allows for the individual testing of core components by disconnecting and reconnecting them as needed, enabling flexible and partial system testing before complete integration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If complete system assembly is performed before testing, then system integration functionality can be verified, but testing time and hardware costs increase significantly

Engineering Contradiction:

Improvesystem integration functionalityVSAvoidtesting time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The testing system is segmented into modular components: individual core components can be tested separately by disconnecting them from the interconnection terminal box, while the integrated system can be tested by connecting all components. This segmentation allows flexible testing at different levels without requiring complete system assembly for every test.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Individual core components can be tested in advance before complete system assembly. The interconnection terminal box is prepared with connection interfaces that allow components to be tested individually or in groups, enabling preliminary verification of component functionality before integration testing.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If complete system assembly is performed before testing, then all components can be tested together, but hardware complexity and testing costs increase

Engineering Contradiction:

Improvesystem integration functionalityVSAvoidhardware complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system is divided into testable segments where the interconnection terminal box serves as a common interface. Core components can be connected or disconnected independently, allowing testing of subsets of components rather than requiring the complete system to be assembled and tested as one complex unit.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The interconnection terminal box provides universal connection interfaces that work with different core components. The same terminal box and testing apparatus can be used to test individual components, pairs of components, or the complete integrated system, eliminating the need for different hardware configurations for different testing scenarios.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If individual component testing is enabled through disconnection, then testing flexibility increases, but system integration verification becomes more complex

Engineering Contradiction:

Improvetesting flexibilityVSAvoidtesting procedure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The testing approach is segmented into hierarchical levels: individual component testing, subsystem testing with multiple components connected to the terminal box, and complete system testing. The terminal box provides consistent interfaces across all levels, making the testing procedure systematic rather than complex.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system allows partial testing where only the necessary components are connected to the terminal box for each specific test objective. This partial action approach enables focused testing of specific functions or components without requiring the entire system to be assembled, reducing unnecessary complexity while maintaining flexibility.

Inventive Principle:

Principle #16Partial or excessive action
