Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external locking devices are used on connector housings, then locking function is achieved, but they are easily damaged and mechanically complex
Solution Approach 1:
The locking device is merged with the connector module itself rather than being separate external components. The camshaft mechanism is integrated into the connector module housing, combining the locking function with the connector structure to reduce overall complexity and improve durability.
Solution Approach 2:
The locking mechanism is nested within the connector module housing. The camshaft and balls are contained inside the connector module, with the camshaft rotating within the housing and balls moving between the pin and receptacle, creating a compact nested arrangement that protects internal components.
2Extent of automation
If traditional mechanical locking devices are used, then locking function is achieved, but they cannot be electronically controlled and are expensive to manufacture
Solution Approach 1:
The patent replaces purely mechanical locking devices with a hybrid system that uses an electric motor to drive the camshaft. This substitution enables electronic control of the locking mechanism while maintaining mechanical locking functionality, and the modular design reduces manufacturing complexity.
Solution Approach 2:
The connector module serves multiple functions: it provides electrical connection through contacts, mechanical locking through the camshaft and balls, and electronic control through the motor and interface. This multi-functionality consolidates several components into one modular unit, reducing overall system complexity and manufacturing cost.
3Ease of manufacture
If simple locking mechanisms are used, then manufacturing cost is reduced, but mechanical stability and security are compromised
Solution Approach 1:
The patent uses spherical balls as the locking elements that interact with the camshaft. The spherical shape allows for smooth engagement and disengagement while providing reliable mechanical interlocking. The camshaft's rounded cam surface works with the spherical balls to create a stable locking mechanism that is simple yet effective.

Function Achieved in This Case
The solution provides a simple, mechanically stable, and cost-effective locking mechanism that can be electronically controlled, ensuring secure and reversible connections between connector modules, protecting them within the housing and allowing for efficient data exchange.
Implementation Method 1
A camshaft (10) is arranged in the first connector module (2), whose axis of rotation (11) runs parallel to the insertion direction of the first connector module (2)
Implementation Method 2
At the end furthest from the journal, the camshaft is connected to an electric motor (12), which can be used to set the camshaft (10) into a rotational movement

AI summary
The invention relates to a system (1) consisting of a first plug module (2) and a second plug module (3), which can be plugged together, wherein the first plug module (2) has a locking means, whereby the plug modules (2, 3) can be reversely locked to each other. Said system can be arranged within the housings of industrial plugs and is thus better protected from mechanical loads.
