Solution Overview

Problem

Current surge arrester drive arrangements are costly and logistically complex due to the need for customer-specific manufacturing to accommodate various control device interfaces, limiting their compatibility with different control devices and environmental conditions.

Innovation Solution

A drive arrangement using standardized plug-in connection devices, such as the Harting 24 DD type, allows connection to multiple control devices without structural changes, enhancing environmental protection to IP65 and temperature resistance to -40°C, eliminating the need for protective hoses and customer-specific connection boxes, and enabling a larger hand crank for easier operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If customer-specific connection boxes are manufactured to accommodate various control device interfaces, then compatibility with different control devices is improved, but manufacturing cost and logistical complexity increase

Engineering Contradiction:
Improvecompatibility with different control devicesVSAvoidmanufacturing cost and logistical complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent applies universality by implementing a standardized connection box design that can accommodate multiple control device interfaces through modular adapter plates. Instead of manufacturing different connection boxes for each control device type, a single universal connection box with interchangeable adapters serves multiple functions, reducing manufacturing complexity while maintaining compatibility with various control devices.

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

2Object-affected harmful factors

If protective hoses are used to protect electrical conductors, then protection against environmental elements is improved, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improveprotection against environmental elementsVSAvoiddevice complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the protective hoses from the system by integrating conductor protection directly into the connection box structure. The connection box itself is designed with sealed compartments and protective features that inherently protect the electrical conductors without requiring separate protective hose components, thereby reducing device complexity while maintaining environmental protection.

Inventive Principle:
Principle #2Taking out (Extraction)

3Device complexity

If the hand crank diameter is reduced to make space for protective conduits, then device complexity is reduced, but ease of operation deteriorates

Engineering Contradiction:
Improvedevice complexityVSAvoidease of operation
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent introduces adapter plates as intermediary components that enable the hand crank to interface with different control device interfaces without requiring a large diameter. The adapter plates act as mediators between the standardized hand crank and various control device connection types, allowing the hand crank to maintain its optimal size for ease of operation while still accommodating different interfaces through the intermediary adapter mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)
