Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processing apparatuses lack effective control over power supply to integrated circuits, particularly when shifting between power-off and standby states, leading to inefficient power management.
Innovation Solution
The proposed processing apparatus includes an integrated circuit with a control unit that manages power states, a power supply unit connected to an external power supply, and a power switch to control the apparatus' state transitions based on user settings and power availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If power supply to the integrated circuit is stopped in energy saving mode, then power consumption is reduced, but the apparatus cannot process job requests efficiently
Solution Approach 1:
The power supply system is segmented into multiple independent control paths: one for the power supply unit and another for the integrated circuit. This allows selective power supply to different components, enabling the apparatus to maintain job processing capability while reducing overall power consumption by powering down only the integrated circuit in energy saving mode.
Solution Approach 2:
The power supply state of the integrated circuit is made dynamic and adjustable. The system can transition between different power states (fully powered, integrated circuit powered down, etc.) based on operational needs, allowing optimization between power consumption and job processing capability depending on the current workload and user preferences.
2Productivity
If the integrated circuit maintains full functionality, then job processing is efficient, but power consumption increases
Solution Approach 1:
The system segments power supply control to allow the integrated circuit to be powered down independently while the power supply unit remains operational. This enables efficient job processing when needed (full power) while reducing power consumption during idle periods (integrated circuit powered down), giving users control over the trade-off between productivity and energy usage.
3Device complexity
If power supply control is simplified, then device complexity is reduced, but power management flexibility is limited
Solution Approach 1:
The power supply control is segmented into distinct functional blocks with clear interfaces. The power supply unit and integrated circuit have separate power control mechanisms, which actually reduces overall complexity by creating modular, independent control systems rather than requiring complex interdependent control logic. This modular approach simultaneously provides flexibility for various power management scenarios.
