Innovation Solution

A modular test bench system with a base frame, test attachments, and extension frames that can be configured to fit various cable harness types, featuring a central test unit for power and communication, allowing quick adaptation to different harness geometries and sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If test benches are designed specifically for one or a few cable harness types, then testing reliability and precision are improved, but adaptability to other cable harness types deteriorates

Engineering Contradiction:
Improvetesting reliabilityVSAvoidadaptability to different cable harness types
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The test bench is divided into modular components including a base frame, interchangeable test attachments, and extension frames. Each test attachment can be selectively mounted on the base frame to accommodate different cable harness geometries, allowing the same physical structure to serve multiple testing purposes without compromising reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The base frame serves as a universal platform that can accommodate various test attachments designed for different cable harness types. The central test unit provides universal power and communication capabilities that work with all test attachments, enabling one test bench system to perform multiple testing functions reliably.

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

2Adaptability or versatility

If test benches are modified to accommodate different cable harness geometries, then adaptability is improved, but manufacturing cost and time increase

Engineering Contradiction:
Improveadaptability to different cable harness geometriesVSAvoidmanufacturing cost and time
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Instead of manufacturing completely different test benches for each cable harness type, the system segments the test bench into a reusable base frame and interchangeable test attachments. This allows the expensive base frame to be manufactured once and reused, while only the relatively inexpensive test attachments need to be manufactured for different geometries.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The test bench configuration can be dynamically changed by swapping test attachments on the base frame. This dynamic reconfigurability eliminates the need for costly remanufacturing when adapting to new cable harness geometries, as the same base frame can quickly accommodate different test attachments.

Inventive Principle:
Principle #15Dynamics

3Measurement precision

If test benches are designed with fixed configurations for specific cable harness types, then testing precision is maintained, but ease of reconfiguration deteriorates

Engineering Contradiction:
Improvetesting precisionVSAvoidease of reconfiguration
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The test bench is segmented into a stable base frame that maintains precise positioning and a set of interchangeable test attachments that can be easily swapped. This segmentation allows the precision features to remain in the base frame while the test attachments provide the necessary geometric variations for different cable harness types.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Test attachments are pre-configured with the specific geometric features needed for different cable harness types before being mounted on the base frame. This preliminary preparation ensures that when a test attachment is installed, the testing precision is immediately available without requiring on-site modifications or complex setup procedures.

Inventive Principle:
Principle #10Preliminary action
