Solution Overview

Problem

Existing contact elements and systems face challenges in providing a reliable and efficient bracing force for securely engaging additional contact elements, which affects the stability and consistency of electrical contact.

Innovation Solution

The contact element features a contact box with spring-elastic sections and a grid structure, including recesses and crosspieces, that provide a clamping force to securely engage additional contact elements, eliminating the need for internal springs and optimizing space usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional internal springs are used in the contact box, then reliable electrical contact can be established, but the device complexity increases and installation space is consumed

Engineering Contradiction:
Improvereliable electrical contactVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent removes the traditional internal spring component from the contact box and replaces it with the elastic functionality of the box sections themselves. The first and third box sections are configured to be elastic, providing the necessary clamping force without requiring separate spring elements, thereby reducing device complexity while maintaining reliable electrical contact.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent combines the structural function of the contact box with the spring function by making the first and third box sections elastic. This merging of structural and spring functions eliminates the need for separate spring components, reducing both device complexity and installation space while ensuring reliable electrical contact through the elastic clamping force.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If traditional internal springs are used in the contact box, then reliable electrical contact can be established, but the installation space increases

Engineering Contradiction:
Improvereliable electrical contactVSAvoidinstallation space
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The patent extracts the spring function from separate components and integrates it into the box sections themselves. The first and third box sections are configured to be elastic, providing clamping force without requiring additional space for separate spring elements, thereby reducing installation space while maintaining reliable electrical contact.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the structural housing function with the spring function by making the box sections elastic. This integration eliminates the need for separate spring components that would occupy additional installation space, while the elastic box sections provide the necessary clamping force for reliable electrical contact.

Inventive Principle:
Principle #5Merging (Combining)

3Strength

If rigid box sections are used throughout, then structural strength is maintained, but the clamping force for additional contact elements is insufficient

Engineering Contradiction:
Improvestructural strengthVSAvoidclamping force
Core Design Contradiction:
StrengthVSForce

Solution Approach 1:

The patent applies different mechanical properties to different parts of the contact box. The second and fourth box sections are configured to be rigid to maintain structural strength, while the first and third box sections are configured to be elastic to provide clamping force. This local differentiation of mechanical properties allows both structural strength and sufficient clamping force to be achieved simultaneously.

Inventive Principle:
Principle #3Local quality
