Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If external sensors and signal detection capabilities are added to the switch, then the functionality and adaptability of the switch are increased, but the device complexity increases

Engineering Contradiction:
ImprovefunctionalityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The switch is designed with universal signal detection capabilities that can handle multiple types of signals (analog and digital) through a single input interface. The electronics include a microprocessor that can evaluate various signal types from different sensors (temperature, light, humidity, etc.), allowing one device to perform multiple functions without requiring separate switching mechanisms for each signal type.

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

Solution Approach 2:

The microprocessor acts as an intermediary between the external sensors and the contact system. It receives and evaluates signals from various sensors, processes the information, and then controls the actuator accordingly. This intermediary layer simplifies the overall system architecture by centralizing the evaluation logic in one component rather than requiring complex direct connections between each sensor and the contact system.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the switch incorporates signal evaluation electronics and external sensor interfaces, then additional functions for monitoring and reacting to input variables are enabled, but the ease of manufacture decreases

Engineering Contradiction:
Improveadditional functionsVSAvoidease of manufacture
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The signal evaluation electronics, including the microprocessor and sensor interfaces, are integrated into a single compact unit within the switch housing. The external sensor connections are merged into a unified input interface that accepts multiple signal types. This consolidation reduces the number of separate components that need to be manufactured and assembled, simplifying the manufacturing process despite the increased functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The electronics are designed with universal interfaces that can accommodate different sensor types without requiring custom manufacturing for each sensor configuration. The microprocessor can be programmed to handle various signal types, allowing the same hardware platform to be manufactured once and then configured for different applications through software rather than hardware modifications.

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

3Extent of automation

If the actuator is operatively connected to the actuating member for automatic switching, then the extent of automation is increased, but the device complexity increases

Engineering Contradiction:
Improveautomatic switchingVSAvoiddevice complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The microprocessor continuously monitors signals from external sensors and automatically activates the actuator when predetermined conditions are met. This feedback mechanism allows the switch to automatically respond to changing conditions without manual intervention. The system evaluates sensor input, compares it against programmed thresholds, and triggers the actuator accordingly, creating a closed-loop automatic control system.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The switch is designed to automatically perform the switching function based on sensor input without requiring external control logic or additional automation components. The microprocessor within the switch itself evaluates the signals and controls the actuator, allowing the device to serve itself by making autonomous decisions about when to switch the contact system based on the evaluated signals.

Inventive Principle:
Principle #25Self-service
