Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golfers face difficulties in accurately determining the distance to a hole due to frequent changes in hole positions, which are not reflected in fixed distance-marking facilities, leading to inefficient club selection and inaccurate shots.
Innovation Solution
A hole location updating device that combines with a flagpole, utilizing a GPS circuit, mobile communication circuit, and control circuit to detect and transmit updated hole positions to a server, minimizing power consumption through a power blocking mode and wake-up signals from buttons or sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the device continuously operates GPS and mobile communication circuits to provide real-time hole position updates, then the information accuracy is improved, but the power consumption increases
Solution Approach 1:
The device operates in periodic cycles, alternating between sleep mode and active measurement mode. The control circuit wakes up at predetermined time intervals to activate the GPS circuit and mobile communication circuit, performs hole position measurement and data transmission, then returns to sleep mode. This periodic operation ensures fresh position information is provided while minimizing power consumption by keeping circuits inactive between cycles.
Solution Approach 2:
The device automatically manages its own power consumption by implementing self wake-up functionality. The control circuit autonomously wakes up at predetermined intervals without external intervention, activates necessary circuits, completes the measurement and transmission tasks, and returns to sleep mode. This self-service mechanism eliminates the need for manual intervention while optimizing the balance between information freshness and power consumption.
2Productivity
If the device operates continuously to ensure real-time hole position updates, then the productivity is improved, but the duration of action decreases due to frequent battery replacement
Solution Approach 1:
The device implements periodic operation with predetermined time intervals between wake-up cycles. This allows the device to provide regular position updates (maintaining productivity) while spending most time in low-power sleep mode (extending battery life and usage duration). The periodic nature ensures position information remains relatively fresh without requiring continuous operation.
Solution Approach 2:
The automatic self wake-up mechanism enables the device to autonomously manage its operational cycles, performing necessary updates only when needed according to the predetermined schedule. This eliminates wasteful continuous operation, extends battery life, and maintains adequate update frequency for practical use without requiring frequent battery replacement.
3Use of energy by moving object
If the device enters power blocking mode to conserve energy, then the power consumption is reduced, but the response time increases when a hole position update is needed
Solution Approach 1:
The device performs preliminary actions by waking up at predetermined time intervals before position changes are likely to occur. The control circuit is programmed to activate at regular intervals, proactively measuring and transmitting position information before the golfer would need it. This preliminary action ensures position data is current without requiring the device to remain continuously active, thus balancing power consumption with response time.
Solution Approach 2:
The predetermined periodic wake-up schedule ensures the device checks and updates position information at regular intervals that are optimized for both power conservation and timely information delivery. The periodic nature creates predictable update timing, ensuring the device responds to position changes within acceptable timeframes while spending most time in low-power mode.
