Innovation Solution

A method and device that adaptively schedule actions based on current energy levels and external events to optimize energy usage, allowing devices to maintain sufficient reserves and extend operation time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If actions are executed frequently to maximize device functionality, then productivity is improved, but energy consumption increases causing premature shutdown

Engineering Contradiction:
Improveaction execution frequencyVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent applies dynamics by making the action execution frequency adaptive rather than fixed. The scheduling system dynamically adjusts when and how often actions are executed based on real-time energy level monitoring. When energy levels are high, more actions can be executed frequently; when energy levels drop, the system automatically reduces execution frequency to conserve energy, thus resolving the contradiction between productivity and energy consumption.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of action execution frequency based on energy conditions. Instead of maintaining a constant high frequency for maximum productivity, the system modifies this parameter dynamically according to available energy levels. This allows the device to operate productively when energy permits while extending operation duration when energy is limited, directly addressing the contradiction between action frequency and energy usage.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If fixed action configurations are used to simplify device operation, then ease of operation is improved, but energy depletes rapidly reducing service life

Engineering Contradiction:
Improveconfiguration simplicityVSAvoidservice life
Core Design Contradiction:
Ease of operationVSDuration of action of stationary object

Solution Approach 1:

The patent implements self-service by enabling the device to automatically adjust its own action configuration based on energy levels without requiring user intervention. The scheduling system autonomously monitors energy status and modifies action frequencies and priorities accordingly. This maintains ease of operation (users don't need to manually reconfigure) while extending service life through adaptive energy management.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent transforms the static fixed configuration into a dynamic adaptive configuration. The action schedule is no longer rigid but flexibly adjusts to energy conditions. This dynamic approach preserves operational simplicity from the user perspective while internally optimizing for extended service life by reducing energy consumption during low-energy periods.

Inventive Principle:
Principle #15Dynamics

3Productivity

If high power actions are executed to maximize functionality, then productivity is improved, but energy reserves deplete faster reducing operational duration

Engineering Contradiction:
Improvefunctionality executionVSAvoidoperational duration
Core Design Contradiction:
ProductivityVSDuration of action of moving object

Solution Approach 1:

The patent changes the power level parameter of executed actions based on energy availability. The scheduling system selectively executes high-power actions only when energy reserves are sufficient, and substitutes them with lower-power alternatives or delays them when energy is limited. This parameter adjustment resolves the contradiction by maintaining productivity when possible while extending operational duration through power management.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies partial action by executing only the necessary subset of high-power actions based on current energy reserves and priority levels. Instead of running all configured actions at full power, the system selectively executes partial sets of actions that provide sufficient functionality while consuming less energy, thereby extending operational duration without completely sacrificing productivity.

Inventive Principle:
Principle #16Partial or excessive action
