Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current input/output devices in data transmission systems rely on a single transmission protocol, leading to increased power consumption due to the use of multiple front chips for protocol conversions and port expansion, which is a significant energy efficiency concern.
Innovation Solution
A chip is designed with an analog receiving circuit, an analog transmission circuit, a digital control circuit, and a switch circuit, operating at different reference voltages to switch between general and sleep modes, reducing power consumption by pausing the supply of certain voltages and using a hot swapping signal to wake up from sleep mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple front chips are used for protocol conversions and port expansion, then the system's adaptability and functionality are improved, but the overall power consumption increases
Solution Approach 1:
The patent merges multiple front chip functions into a single chip by integrating protocol conversion capabilities and multiple I/O ports within one device. This consolidation eliminates the need for multiple separate front chips, thereby reducing overall system power consumption while maintaining the adaptability and versatility previously achieved through multiple chips.
Solution Approach 2:
The single front chip is designed with multi-functionality to perform various protocol conversions and handle multiple I/O ports simultaneously. This universal design allows the chip to replace multiple specialized front chips, reducing the total number of active components and consequently lowering system-wide power consumption.
2Productivity
If the chip operates continuously in general mode, then the system responsiveness is maintained, but the power consumption cannot be reduced
Solution Approach 1:
The chip implements dynamic power management by switching between two operational states: general mode for active data transmission and sleep mode for power savings. The system dynamically transitions between these states based on operational requirements, allowing the chip to maintain responsiveness when needed while significantly reducing power consumption during idle periods.
Solution Approach 2:
The chip employs periodic monitoring of wake-up conditions during sleep mode, periodically checking for incoming data or connection events. This periodic action ensures the chip can quickly transition back to general mode when needed, maintaining system responsiveness while minimizing power consumption during extended idle periods.
3Use of energy by moving object
If the chip enters sleep mode to reduce power consumption, then the power savings are achieved, but the complexity of mode switching increases
Solution Approach 1:
The chip implements self-service mode switching by automatically transitioning between general and sleep modes based on operational conditions. The system monitors its own state and data transmission requirements, making decisions about mode transitions without external intervention. This self-service approach simplifies the control complexity by eliminating the need for complex external control mechanisms.
Solution Approach 2:
The chip employs feedback mechanisms where the digital control circuit continuously monitors operational status, data transmission requirements, and power consumption levels. Based on this feedback, the system automatically adjusts its operating mode, simplifying the switching control through intelligent decision-making rather than complex predetermined control logic.
