Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional wiring with plug connectors and cables is used, then electrical connections can be established, but the space requirement becomes very large and manual labor is required for each change

Engineering Contradiction:
Improveease of reconfigurationVSAvoidinstallation space
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The system is divided into modular sliding elements that can be independently positioned and configured. Each sliding element contains multiple contact points that can be selectively engaged, allowing the system to be reconfigured by moving individual modules rather than rewiring entire connections. This segmentation enables compact arrangement while maintaining reconfigurability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sliding elements are designed to be movable along guide rails or within designated paths, transforming the static wiring structure into a dynamic system. This allows electrical connections to be reconfigured by simply sliding components to new positions, eliminating the need for manual wire removal and installation while reducing the space required for connection points.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If manual cabling is performed for each connection change, then electrical connections can be updated, but the process becomes very time-consuming and costly

Engineering Contradiction:
Improveadaptability of electrical connectionsVSAvoidtime for wiring changes
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The sliding elements enable dynamic reconfiguration of electrical connections through simple linear motion along guides. This transforms the time-consuming manual wiring process into a quick sliding operation, allowing connections to be changed by moving pre-configured contact elements to new positions rather than performing complete rewiring procedures.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Multiple contact points and connection paths are pre-configured within the sliding elements during manufacturing. When reconfiguration is needed, the system simply requires moving these pre-prepared elements to appropriate positions, eliminating the need for on-site wiring decisions and manual connection-making, thus significantly reducing changeover time.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If fixed wiring is used in telephone line junction boxes, then stable electrical connections are achieved, but changes require complete rewiring and employee intervention

Engineering Contradiction:
Improvestability of electrical connectionsVSAvoidease of changing connections
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system combines the stability of fixed connections with the flexibility of movable components. Sliding elements maintain reliable electrical contact through spring-loaded or resilient contact mechanisms while being constrained to move along predefined paths, ensuring stable connections during operation but allowing easy reconfiguration when needed by simply sliding to new positions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The sliding elements act as intermediaries between the fixed structural framework and the electrical connection requirements. These intermediate components provide stable, reusable contact points that can be repositioned along guide rails, eliminating the need for complete rewiring while maintaining reliable electrical connections throughout the system.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Adaptability or versatility

If multiple plug connectors are installed for every possible connection position, then all connection options are available, but the switch cabinet requires significantly more installation space

Engineering Contradiction:
Improvenumber of connection positionsVSAvoidswitch cabinet space
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

Each sliding element is designed as a universal component that can serve multiple connection functions. By moving a single sliding element along a guide rail, it can engage with different contact points to create various electrical connections, replacing the need for multiple dedicated plug connectors at different locations. This multi-functionality dramatically reduces the space required while maintaining all connection options.

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

Solution Approach 2:

The connection system is segmented into reusable sliding elements that traverse along shared guide structures. Instead of installing separate connectors for each possible connection, the system uses segmented, movable elements that can be positioned to create any required connection, reducing the overall footprint of the switch cabinet while preserving full connection versatility.

Inventive Principle:
Principle #1Segmentation

AI summary

The invention relates to a sliding element (1) for electrically contacting conductor paths on two facing printed circuit boards (10). The sliding element (1) consists of a main body (2), at least one electrical contact element (3), and a through-hole (6) provided for accepting a threaded stud (11). An internal thread (7) in the through-hole (6) allows the sliding element (1) to move linearly along the threaded stud (11) when the threaded stud (11) is twisted. By sliding the sliding element (1) along the threaded stud (11), different conductor paths on the printed circuit boards (10) are brought into electrical contact with one another.
