Solution Overview

Problem

Existing surge protection devices require complete system shutdown for module replacement, leading to inefficiencies and high costs due to low repeatability and poor structural integrity of multipolar bases formed by splicing unipolar bases, which are complex to install and lack pre-wiring.

Innovation Solution

A spliced surge protection device base that allows direct formation of unipolar or multipolar bases through modular components, with integrated installation of elements like bus bars and microswitches, reducing complexity and cost by using a three-part housing system with through holes for connected elements and a remote signaling alarm mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If an integral type base with complete structure is used, then structural strength and appearance are improved, but manufacturing cost increases and repeatability decreases

Engineering Contradiction:
Improvestructural strengthVSAvoidmanufacturing cost
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The base is divided into a first housing and a second housing that can be spliced together. Each housing can be manufactured separately using standardized processes, then assembled through splicing. This segmentation allows for repeated use of identical housing components across different base configurations, reducing manufacturing cost while maintaining structural integrity through the splicing connection.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If an assembled type base with spliced unipolar bases is used, then manufacturing cost decreases, but structural integrity and appearance deteriorate

Engineering Contradiction:
Improvemanufacturing costVSAvoidstructural integrity
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The first housing and second housing are spliced together to form an integrated multipolar base structure. The splicing connection merges the two separate housings into a unified whole that provides structural integrity comparable to integral types. Elements such as bus bars and microswitches are installed within the spliced housing, creating a cohesive assembly that maintains stability and composition integrity.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If an assembled type base with spliced unipolar bases is used, then manufacturing cost decreases, but device complexity and installation difficulty increase

Engineering Contradiction:
Improvemanufacturing costVSAvoidinstallation complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The bus bars and microswitches are pre-installed within the spliced housing structure during the manufacturing process. This preliminary action eliminates the need for complex field installation and wiring operations. The housing is designed with pre-configured mounting positions and connection points, allowing for straightforward assembly and reducing installation complexity while maintaining cost-effectiveness.

Inventive Principle:
Principle #10Preliminary action

4Ease of manufacture

If an assembled type base with spliced unipolar bases is used, then manufacturing cost decreases, but electrical integration and pre-wiring capability are lost

Engineering Contradiction:
Improvemanufacturing costVSAvoidpre-wiring capability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The spliced housing structure is designed to accommodate multiple elements (bus bars, microswitches, and other components) within a single integrated assembly. The universal design allows the same first and second housing components to be used across different base configurations, providing pre-wiring capability and electrical integration. The housing includes standardized connection points and mounting structures that enable flexible adaptation to different surge protection device requirements.

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

AI summary

A surge protection device base (121) comprises: a first housing (101), a second housing (102) and a third housing (103). The first housing (101) is provided with at least one first structure. The second housing (102) is provided with at least one second structure. The third housing (103) is provided with at least one first structure and at least one second structure. The first structure is positioned at a second half side of the third housing (103) while the second structure is positioned at a first half side of the third housing (103). One first housing (101), one or more third housings (103) and one second housing (102) are spliced together to form a multipolar surge protection device base (121). The first housing (101) and a first half side of the third housing (103) adjacent thereto constitute a unipolar surge protection device base (121), a second half side and a first half side of the two adjacent third housings (103) constitute a unipolar surge protection device base (121), and the second housing (102) and a second half side of the third housing (103) adjacent thereto constitute a unipolar surge protection device base (121).
