Solution Overview

Problem

Current materials lack the ability to respond to changing environmental conditions, stress, or damage in a targeted manner and cannot learn optimal behavior automatically or with control computer assistance, as they either lack actuators or have uncontrolled external actuator control without internal sensors.

Innovation Solution

A system comprising sensors, actuators, an analyzer, interpreter, behavior controller, articulator, and synthesizer that analyzes sensor signals, interprets them semantically, and generates actuator signals for adaptive behavior, allowing the material to react to changing states and learn from previous responses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If smart materials with embedded sensors are used, then the material can detect environmental conditions and stress, but the material cannot react to stimuli because it lacks actuators

Engineering Contradiction:
Improvedetection capabilityVSAvoidreaction capability
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent combines sensors, actuators, and control electronics into an integrated smart material system. The sensors detect environmental conditions, the control system processes this information, and the actuators execute appropriate reactions, creating a unified material that both detects and responds to stimuli autonomously.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The smart material system is designed to perform multiple functions: sensing environmental conditions, processing information through semantic interpretation, deciding on appropriate responses, and executing physical actions. This multi-functional integration enables the material to adapt to various situations beyond simple detection.

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

2Ease of operation

If actuators are controlled externally, then the material can be influenced, but the actuators cannot define their own actions because they lack internal sensors

Engineering Contradiction:
Improveexternal control capabilityVSAvoidautonomous action capability
Core Design Contradiction:
Ease of operationVSExtent of automation

Solution Approach 1:

The patent implements a feedback loop where internal sensors continuously monitor the material's state and environmental conditions, this information is processed by a control system, and actuators adjust their actions accordingly. This closed-loop feedback enables autonomous decision-making and self-regulation without requiring constant external control.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The smart material system is designed to autonomously sense its own state through embedded sensors, process this information internally, and execute corrective actions through actuators without external intervention. The material serves itself by independently detecting problems and implementing solutions.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If materials are designed to respond to stimuli, then they exhibit reflex-like behavior, but this does not constitute goal-directed behavior

Engineering Contradiction:
Improveresponse capabilityVSAvoidbehavioral organization complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic behavioral organization where the material's response strategy adapts based on the current situation. The semantic interpretation system evaluates environmental context and material state to dynamically select appropriate responses, transitioning from fixed reflex patterns to flexible, goal-directed behavior that adjusts to changing conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The smart material system pre-programmes multiple possible response strategies and selects the appropriate one based on semantic interpretation of the current situation. This allows the material to plan and execute goal-directed sequences of actions rather than simple reactive responses, anticipating needed actions based on interpreted environmental cues.

Inventive Principle:
Principle #10Preliminary action

AI summary

The invention relates to a device and a method for controlling actuators of a system which has the actuators and sensors. The device comprises an interpreter for interpreting an analysis result from an analysis of sensor signals of the sensors. A plurality of different interpretation hypotheses which constitute different meanings of the analysis result can be obtained from the analysis result. A behavior controller is designed to supply a reaction to the plurality of different interpretation hypotheses. An articulator is designed to generate an articulation from the reaction, control signals for the actuators being producible from the articulation by means of a synthesizing process. The interpreter is further designed to start the plurality of different interpretation hypotheses and to continue the started interpretation hypotheses using confidences or probabilities. The degrees of confidence and the probabilities are defined by a specified initial state of the system or by a system history.
