Solution Overview

Problem

Existing switching elements, such as relays and contactors, face reliability issues due to unintentional disconnection with plug-type contacts and high production complexity and costs associated with soldering, especially when handling high currents.

Innovation Solution

An active electrical component with plug-type or pressing contacts and a force transmission structure composed of chains of rigid members that transmit forces from the component's side opposite the contacts, allowing for reliable high-current connections without mechanically loading other components, using a housing made from thermoplastic materials for cost-effective production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If plug-type contacts are used for connection, then ease of insertion and separation is improved, but reliability deteriorates due to unintentional disconnection

Engineering Contradiction:
Improveease of insertionVSAvoidconnection reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The contact is designed with elastic properties, allowing it to dynamically adapt during insertion and operation. The elastic contact can deform to engage with the counter-contact and maintain continuous pressure, ensuring reliable connection while remaining easy to insert. This dynamic behavior resolves the contradiction between ease of operation and connection reliability.

Inventive Principle:
Principle #15Dynamics

2Reliability

If soldering is used to connect contact and counter-contact, then connection reliability is improved, but manufacturing complexity and cost increase

Engineering Contradiction:
Improveconnection reliabilityVSAvoidproduction complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the thermal soldering process with a mechanical connection system. The elastic contact mechanically engages with the counter-contact through insertion, eliminating the need for soldering equipment and thermal processes. This mechanical substitution maintains connection reliability while significantly reducing manufacturing complexity and cost.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If soldering is used to connect contact and counter-contact, then connection reliability is improved, but production cost increases

Engineering Contradiction:
Improveconnection reliabilityVSAvoidproduction cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces the thermal soldering process with a mechanical connection system. The elastic contact mechanically engages with the counter-contact through insertion, eliminating the need for soldering equipment and thermal processes. This mechanical substitution maintains connection reliability while significantly reducing manufacturing complexity and cost.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Reliability

If high forces are applied to insert the contact, then connection reliability is improved, but mechanical loading of other components increases

Engineering Contradiction:
Improveconnection retention forceVSAvoidmechanical loading on components
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The patent extracts the force transmission function into a dedicated force transmission structure that is separate from the contact itself. This structure is designed to handle high insertion forces and transmit them to the mounting structure, preventing these forces from being transmitted to other sensitive components like the coil or armature. This separation allows high retention forces while protecting other components from excessive mechanical loading.

Inventive Principle:
Principle #2Taking out (Extraction)
