Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Old batteries or batteries not used for extended periods may fail to provide sufficient power to start a vehicle's motor or engine due to high contact impedances caused by dirty, rusted, and corroded connections, which can lead to suboptimal connections and potential safety hazards.
Innovation Solution
A power supply with clamps that connect to the device or battery contacts, incorporating a detection module to measure contact impedance, a power switch controlled by a system control module to ensure optimal energy transfer, and user prompts to adjust connections for optimal impedance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an emergency starting power supply is used to provide power directly to the device, then the device can be started without charging the battery, but the connection points may have large contact impedances due to dirt, rust, and corrosion resulting in suboptimal connections and potential safety hazards
Solution Approach 1:
The system performs preliminary impedance detection before enabling power delivery. The detection module measures contact impedance in advance, and the control module prevents power delivery until acceptable connection quality is confirmed, eliminating the need for trial-and-error connection attempts
Solution Approach 2:
The system implements real-time feedback through the detection module that continuously monitors contact impedance during the connection process. The control module receives this feedback and dynamically adjusts the power delivery state, providing visual feedback to users about connection quality through LED indicators
2Reliability
If a battery charger is used to charge the battery, then the battery can supply sufficient power to start the motor or engine, but charging can take a long time and accessing the battery can be onerous
Solution Approach 1:
The emergency starting power supply acts as an intermediary device that provides power directly to the device's motor or engine without needing to charge the device's battery. This bypasses the time-consuming battery charging process while still enabling the device to receive sufficient starting power
Solution Approach 2:
The system performs preliminary impedance detection to verify safe direct power delivery conditions before enabling power transfer, ensuring that sufficient power can be delivered directly without requiring battery charging
3Ease of operation
If direct power delivery is enabled without impedance detection, then the system is simpler and faster to operate, but large contact impedances can cause suboptimal connections and dangerous situations such as sparks and potential fires
Solution Approach 1:
The system applies preliminary anti-action by detecting contact impedance before power delivery is enabled. The detection module identifies potentially dangerous high-impedance connections in advance, and the control module prevents power delivery that would otherwise create sparks or fire hazards
Solution Approach 2:
Real-time impedance detection provides continuous feedback to the control module, which adjusts power delivery accordingly. Visual LED feedback informs users of connection safety, enabling fast operation without compromising safety
