Solution Overview

Problem

Manual connection and disconnection of energy supply connectors to vibrators in concrete production plants pose safety risks and increase operator intervention, especially in noisy and dusty environments, and are prone to misalignment due to component tolerances and wear.

Innovation Solution

A coupling system with automatic centring and locking mechanisms allows for remote connection and disconnection of energy supply to vibrators, using actuators and centring means to align connectors accurately without manual intervention, and includes protection against contamination and vibrations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual connection is used between connector and further connector, then operator can make connection, but operator safety deteriorates due to exposure to noisy and dusty environment and risk of accidents

Engineering Contradiction:
Improveoperator ability to make connectionVSAvoidoperator safety
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The coupling system performs the connection operation automatically without operator intervention. The actuator moves the connector along the advancement direction to couple with the further connector, and the centring means centres the further connector with respect to the connector, enabling the system to service itself and eliminate operator exposure to harmful factors

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual mechanical operation of connecting and disconnecting connectors is replaced by an automated actuator mechanism. The actuator mechanically moves the connector to achieve coupling, substituting the operator's manual mechanical action with an automated mechanical system that improves safety

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

2Ease of operation

If manual intervention is used for connecting and disconnecting connectors, then connection can be made, but productivity deteriorates due to time consumption and reduced automation

Engineering Contradiction:
Improveconnection capabilityVSAvoidproduction automation level
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The coupling system autonomously performs the connection and disconnection operations through the actuator and centring means, eliminating the need for operator intervention. This automation directly improves productivity by reducing manual labor and increasing the automation level of the concrete product production plant

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The centring means centres the further connector with respect to the connector in advance before the actual coupling occurs. This preliminary positioning action ensures that the connectors are properly aligned before the actuator completes the connection, enabling smooth automated operation without operator intervention

Inventive Principle:
Principle #10Preliminary action

AI summary

A coupling system is intended for coupling an apparatus for supplying energy (AE) and a mould (S) for producing concrete products, such that the apparatus for supplying energy (AE) can supply energy to at least one vibrator fitted to the mould (S). The coupling system (1) comprises a first coupling portion (2) having a connector (9) that is connectable to the apparatus for supplying energy (AE) and a second coupling portion (3) having a further connector (10) that is connectable to the vibrator. An actuator (7) is provided for moving the connector (9) along an advancement direction (X) so as to cause the connector (9) to couple with the further connector (10). The coupling system (1) further comprises centring means (23, 24, 25, 35, 36, 37) for centring the further connector (10) with respect to the connector (9).
