Solution Overview

Problem

Existing coupling arrangements for terminal connectors and circuit boards are not cost-efficient, require additional wiring, and lack a compact and reliable connection method, making them difficult to assemble and maintain.

Innovation Solution

A coupling arrangement that mechanically and electrically connects terminal connectors directly to circuit boards using complementary connection structures, eliminating the need for additional wiring and providing a reversible, stable, and compact connection, with features like guide rails, latching elements, and standardized pin connections for secure and flexible conductor insertion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If additional wiring and devices are used to connect terminal connectors to circuit boards, then electrical connection can be achieved, but assembly complexity and cost increase

Engineering Contradiction:
Improveelectrical connectionVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the terminal connector and circuit board into a single integrated assembly where the terminal connector is directly mounted on the circuit board. This merging eliminates the need for separate wiring and connection devices, reducing assembly complexity while maintaining reliable electrical connection through the integrated design.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The circuit board serves multiple functions: it provides the electrical circuitry, the mounting structure for the terminal connector, and the mechanical support for the entire assembly. This multi-functionality eliminates the need for separate wiring harnesses and connection devices, simplifying the overall system while ensuring reliable electrical connections.

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

2Reliability

If traditional wiring methods are used to connect terminal connectors to circuit boards, then electrical connection is achieved, but the overall size and weight of the assembly increase

Engineering Contradiction:
Improveelectrical connectionVSAvoidassembly weight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

By merging the terminal connector and circuit board into a single integrated unit, the patent eliminates the weight of separate wiring harnesses, connectors, and mounting devices. The integrated design achieves reliable electrical connection while minimizing the overall weight of the assembly.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If terminal connectors are directly mounted on circuit boards, then assembly is simplified and size is reduced, but the connection may be too permanent to allow easy maintenance or replacement

Engineering Contradiction:
Improveassembly simplicityVSAvoidmaintenance accessibility
Core Design Contradiction:
Ease of manufactureVSEase of repair

Solution Approach 1:

The patent segments the integrated assembly into separable components: the terminal connector unit can be removed from the circuit board. This segmentation allows the assembly to be simple and compact during manufacturing, while enabling easy disassembly for maintenance or replacement by separating the terminal connector from the circuit board.

Inventive Principle:
Principle #1Segmentation

4Reliability

If wiring is used to connect terminal connectors to circuit boards, then electrical connection is achieved, but strain relief and additional components are required

Engineering Contradiction:
Improveelectrical connectionVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the electrical connection function directly into the mechanical mounting structure. The terminal connector is electrically connected to the circuit board through direct contact points integrated into the mounting interface, eliminating the need for separate wiring and strain relief components. This reduces the total number of components while maintaining reliable electrical connection.

Inventive Principle:
Principle #5Merging (Combining)
