Solution Overview

Problem

Existing control devices for valve systems face challenges in simplifying the interconnection of individual control sections, requiring significant effort for expansion and potentially compromising IP protection due to cable harness seals during testing.

Innovation Solution

A modular control device with T-piece-like connecting parts that form a longitudinal link, allowing for easy expansion and replacement of defective parts, featuring a sealing device and locking mechanism for secure connections, eliminating the need for cumbersome wiring harnesses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If custom-made cable harnesses or daisy chain connections are used to connect control sections, then the control sections can be interconnected, but the effort and complexity for connecting and expanding control sections increases significantly

Engineering Contradiction:
ImproveEase of connectionVSAvoidConnection complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cable harness is divided into separate T-shaped connection parts that can be independently attached to each control section. Each control section receives only the connection parts it needs, eliminating the complexity of assembling entire cable harnesses and enabling simple daisy-chain connections between sections.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection system transitions from planar cable harness connections to three-dimensional T-shaped connectors that can be attached at multiple orientations. This allows connections to be made from different directions and simplifies the interconnection geometry, reducing assembly complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If cable harnesses with Y-junctions are used to connect control sections, then multiple sections can be interconnected, but the seals at Y-junctions represent potential weak points during IP protection class testing

Engineering Contradiction:
ImproveExpansion capabilityVSAvoidIP protection reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The cable harness is segmented into separate T-shaped connection parts that can be independently attached to each control section. Each control section receives only the connection parts it needs, eliminating the complexity of assembling entire cable harnesses and enabling simple daisy-chain connections between sections.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection system transitions from planar cable harness connections to three-dimensional T-shaped connectors that can be attached at multiple orientations. This allows connections to be made from different directions and simplifies the interconnection geometry, reducing assembly complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If individual control sections are connected using series connection parts, then the control sections can be interconnected in a chain, but the effort for connecting varying numbers of control sections or expanding the control block increases significantly

Engineering Contradiction:
ImproveFlexibility in configurationVSAvoidConnection time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The cable harness is divided into separate T-shaped connection parts that can be independently attached to each control section. Each control section receives only the connection parts it needs, eliminating the complexity of assembling entire cable harnesses and enabling simple daisy-chain connections between sections.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The T-shaped connection parts are pre-assembled and attached to each control section before installation. This preliminary preparation eliminates the need for on-site cable harness assembly and enables quick connection by simply plugging in the pre-configured T-connectors.

Inventive Principle:
Principle #10Preliminary action
