Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple separate control units are used for actuators and additional units, then functional control is achieved, but device complexity and number of components increase

Engineering Contradiction:
Improvecontrol functionalityVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the control unit for actuators and the control unit for additional units into a single integrated control unit. This control unit has a control device with an actuator interface for connecting actuators and an additional unit interface for connecting additional units, eliminating the need for separate control units and reducing overall system complexity while maintaining full control functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The control unit is designed with multi-functional capability to handle both actuator control and additional unit control through a single device. The control device can simultaneously manage actuator units connected via the actuator interface and additional units connected via the additional unit interface, making the control unit universal and reducing the total number of components needed.

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

2Reliability

If separate connector elements are used for actuators and additional units, then clear signal paths are maintained, but ease of operation and integration are reduced

Engineering Contradiction:
Improvesignal path clarityVSAvoidconnection simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The control unit integrates both the actuator interface and additional unit interface into a single connector element. This allows actuators and additional units to be connected simultaneously to the same control unit through one integrated connector, simplifying the connection process while maintaining distinct signal paths through the control device's internal architecture.

Inventive Principle:
Principle #5Merging (Combining)
