Solution Overview

Problem

Existing terminal blocks for electrical systems are limited in their application due to high production costs and inefficient use of installation space, as they are designed to be functionally different but have identical housing shapes for mounting on top-hat rails, leading to unused depth in installation spaces.

Innovation Solution

An adapter housing system with complementary connecting means for reversible connection of adapter housings and a top-hat rail fixing element, allowing multiple adapter housings with contact carriers to be connected and aligned on top-hat rails, expanding the application of existing contact carriers and utilizing previously unused space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If terminal blocks are designed with identical housing shapes for mounting on top-hat rails, then mounting compatibility is improved, but production costs increase due to small quantities of individual terminal blocks

Engineering Contradiction:
Improvemounting compatibilityVSAvoidproduction cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The terminal block system is divided into two independent parts: a standardized adapter housing for mounting and individual contact carriers for specific functions. This segmentation allows the adapter housing to be produced in large quantities for cost efficiency while contact carriers can be customized for different applications.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adapter housing serves as a universal mounting component that can accommodate multiple different contact carriers with various functions. This multi-functionality allows a single standardized housing design to support diverse terminal block applications, reducing the need to manufacture different housing shapes for each function.

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

2Area of stationary object

If terminal blocks are lined up next to each other on top-hat rails, then width space is optimized, but depth space is wasted

Engineering Contradiction:
Improvewidth utilizationVSAvoiddepth utilization
Core Design Contradiction:
Area of stationary objectVSVolume of moving object

Solution Approach 1:

The adapter housing extends in the depth direction beyond the top-hat rail, creating additional usable space in the previously underutilized depth dimension. This allows contact carriers to be positioned optimally while utilizing both width and depth spaces effectively.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If adapter housings are connected with locking mechanisms, then connection reliability is improved, but device complexity increases

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

Solution Approach 1:

The locking mechanism is integrated directly into the adapter housing structure itself, merging the housing and locking components into a single unified part. This integration reduces the number of separate components and assembly steps while maintaining reliable locking functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The locking mechanism is designed to automatically engage when adapter housings are connected, eliminating the need for separate manual locking operations. The complementary connecting means with locking elements perform the locking function automatically during the connection process.

Inventive Principle:
Principle #25Self-service
