Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The challenge is to balance cellphone working time and standby time while minimizing power consumption, as processor-heavy applications consume significant power, and existing technologies fail to maintain sensor functionality during dormant states without awakening the processor.

Innovation Solution

A method where a subscriber identity module card maintains a working power supply to specified electronic devices like sensors during dormant states, collecting and storing data, allowing the processor to remain dormant longer by extracting data when the terminal resumes activity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the processor remains in a dormant state to save power, then power consumption is reduced, but sensor functionality cannot be maintained

Engineering Contradiction:

Improvepower consumptionVSAvoidsensor functionality

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The system is segmented into two independent operational paths: one for the processor (which can enter dormant state) and one for the SIM card (which remains active). The SIM card is given independent capabilities to collect and store sensor data without requiring processor involvement, thus maintaining sensor functionality while allowing the processor to save power.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The SIM card acts as an intermediary component between the sensor and the processor. It collects sensor data during the processor's dormant period and transfers it to the processor when activated, bridging the gap between power-saving mode and sensor data acquisition.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the processor stays active to maintain sensor functionality, then sensor data collection is continuous, but power consumption increases

Engineering Contradiction:

Improvesensor functionalityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system separates the data collection function from the processor by assigning it to the SIM card. This segmentation allows the processor to remain dormant while the SIM card independently maintains sensor functionality and collects data.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The SIM card performs self-service by autonomously collecting sensor data, storing it in its own memory, and managing data transfer to the processor without requiring the processor to remain active. This eliminates the need for continuous processor operation.

Inventive Principle:

Principle #25Self-service

3Duration of action of stationary object

If the processor enters dormant state to extend standby time, then standby time is extended, but working time is reduced

Engineering Contradiction:

Improvestandby timeVSAvoidworking time

Core Design Contradiction:

Duration of action of stationary objectVSDuration of action of moving object

Solution Approach 1:

The SIM card performs preliminary action by collecting and storing sensor data during the processor's dormant standby period. This preliminary data collection ensures that when the processor becomes active, there is already accumulated data ready for processing, effectively extending the productive working time without compromising standby duration.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The SIM card maintains continuous useful action by constantly collecting sensor data even when the processor is dormant. This continuity ensures that no data is lost during standby periods and that the processor can immediately resume productive work upon activation.

Inventive Principle:

Principle #20Continuity of useful action

4Productivity

If sensor data is collected continuously to improve productivity, then data availability is improved, but power consumption increases

Engineering Contradiction:

Improvedata collection efficiencyVSAvoidpower consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The data collection function is segmented from the power-consuming processor and assigned to the low-power SIM card. This allows continuous data collection (improving productivity) while maintaining low power consumption, as the SIM card operates independently of the processor's power state.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system changes the operational parameters by allowing the SIM card to operate in a low-power mode while performing data collection tasks that would traditionally require the high-power processor. This parameter change enables continuous data collection with significantly reduced energy consumption.

Inventive Principle:

Principle #35Parameter changes
