Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual addressing of electrical elements is used, then each electrode can be assigned to a recording channel location, but the process becomes cumbersome and time-consuming

Engineering Contradiction:
Improveaddressing accuracyVSAvoidaddressing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The electrical elements are equipped with self-addressing capabilities through integrated microelectronic circuits or passive addressing circuits that automatically generate and transmit addressing signals. This self-service mechanism eliminates the need for manual addressing, thereby reducing addressing time while maintaining accuracy through automated signal transmission and decoding processes.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical manual addressing process with an automated electrical system. Microelectronic circuits generate addressing signals that are transmitted through the electrical elements themselves, substituting the manual mechanical assignment process with an automated electrical signaling and decoding system, thus dramatically reducing addressing time.

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

2Reliability

If manual addressing of electrical elements is used, then addressing can be performed, but the process is prone to errors

Engineering Contradiction:
Improveaddressing reliabilityVSAvoidaddressing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The self-addressing mechanism uses automated microelectronic circuits to generate and transmit addressing signals without human intervention. This eliminates manual errors while maintaining reliability through consistent automated signal generation and decoding, reducing both time and error rates simultaneously.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system incorporates feedback mechanisms where the acquisition system transmits addressing signals to the electrical elements and receives confirming responses. This closed-loop feedback ensures accurate pairing between electrical elements and recording channel locations, enhancing reliability while the automated process reduces time consumption.

Inventive Principle:

Solution Approach 1:

Each electrical element performs self-addressing through integrated microelectronic circuits that automatically generate addressing signals. This self-service capability enables the system to handle large numbers of electrodes simultaneously without requiring proportional increases in manual labor, thus maintaining high productivity as the quantity of electrodes increases.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The electrical elements are pre-configured with addressing circuits and identification signals during manufacturing. This preliminary action ensures that when deployed in large-scale applications, the elements can be quickly identified and assigned to recording channels without time-consuming manual processes, thereby maintaining high productivity regardless of the number of electrodes.

Inventive Principle:

4Productivity

If self-addressable electrical elements with microelectronic circuits are used, then addressing time is reduced, but device complexity increases

Engineering Contradiction:

Solution Approach 1:

The microelectronic circuits integrated into the electrical elements serve multiple functions: they amplify recording signals, generate addressing signals, and transmit identification information. This multi-functionality reduces the need for separate dedicated addressing hardware, thereby limiting the increase in overall system complexity while maintaining high addressing speed.

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

Solution Approach 2:

The addressing circuitry is nested within the electrical element structure itself, with microelectronic circuits integrated directly into the electrode assembly. This nesting approach consolidates multiple functions into a single integrated unit, minimizing the increase in external system complexity while enabling rapid self-addressing capabilities.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

The present disclosure relates generally to automating the task of assignment of labels to identify electrical elements (e.g., electrode contacts, electrodes including a plurality of electrode contacts, and/or non-addressable electrical elements, like wires). A system that can automate the task of assignment of labels can include an electrical element, a microelectronic circuit associated with the electrical element, and an acquisition system. The microelectronic circuit can transmit a sequence comprising a label corresponding to the electrical element. The acquisition system can assign the label corresponding to the electrical element to a recording channel after decoding the sequence.
