Solution Overview

Problem

Data processing systems face power consumption issues due to repeated processing through data detector and decoder circuits, leading to potential under-voltage conditions and increased error rates, exceeding the capacity of existing power supplies.

Innovation Solution

Incorporating a gating circuit to manage power usage by delaying the application of data detection and decode algorithms, calculating extended delay periods based on expected power usage and operational levels to spread power consumption over a larger period, thereby preventing power supply overload.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If data sets are processed repeatedly through data detector and decoder circuits to ensure data accuracy, then data processing reliability is improved, but power consumption increases and may exceed power supply capability

Engineering Contradiction:

Improvedata processing reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The gating circuit introduces periodic delays between processing operations on different data sets, creating a rhythm of activity that allows power consumption to be distributed over time. The circuit alternates between active processing periods and idle periods, preventing continuous peak power draw while maintaining the necessary repeated processing for reliability.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system dynamically adjusts the timing of processing operations based on power supply capabilities. The gating circuit modifies the operational schedule of data detector and decoder circuits, making the processing timing flexible rather than fixed, to accommodate power constraints while preserving data processing reliability.

Inventive Principle:

Principle #15Dynamics

2Productivity

If data processing operations are performed continuously without delay to maximize throughput, then productivity is improved, but power supply may become overloaded causing under-voltage conditions

Engineering Contradiction:

Improvedata processing throughputVSAvoidpower supply load

Core Design Contradiction:

ProductivityVSPower

Solution Approach 1:

The gating circuit implements periodic action by introducing controlled delays between processing operations. Instead of continuous operation, the system processes data sets in periodic bursts separated by idle periods, which reduces instantaneous power demand while maintaining overall productivity through efficient utilization of processing resources.

Inventive Principle:

Principle #19Periodic action

3Use of energy by moving object

If delays are introduced to spread power usage and prevent power supply overload, then power consumption is managed, but processing time increases

Engineering Contradiction:

Improvepower usage managementVSAvoidprocessing time

Core Design Contradiction:

Use of energy by moving objectVSLoss of time

Solution Approach 1:

The gating circuit acts as an intermediary between the data processing circuits and the power supply. It mediates the timing of power consumption by introducing strategic delays, smoothing the power demand profile to match power supply capabilities while minimizing the impact on overall processing time through intelligent delay placement.

Inventive Principle:

Principle #24Intermediary (Mediator)
