Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional internal combustion engine generators face limitations in noise, vibration, smoothness, efficiency, and emissions, and are often undersized due to cost considerations, leading to 'trip-outs' when demand exceeds their limited output.
Innovation Solution
A remote-controlled generator with an internal combustion engine featuring an opposed cylinder design and communication capabilities for software updates and data transmission, allowing for remote monitoring and adjustment of power output to match demand, and a method to lease generators rated below capacity for selective upscaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a smaller generator is purchased to reduce initial cost, then purchase and installation cost is reduced, but the generator may trip-out when demand exceeds its limited output
Solution Approach 1:
The patent applies dynamics by enabling the generator's power output to be dynamically adjusted through remote control. The generator can operate at different power levels (e.g., 30kW or 50kW) based on real-time demand, allowing a smaller generator to reliably meet variable demands that would otherwise require a larger, more expensive unit. This dynamic adaptability resolves the contradiction between initial cost and reliability.
Solution Approach 2:
The patent changes the operational parameters of the generator by allowing remote modification of power output settings. The control unit can adjust the generator's capacity based on monitored demand, enabling cost-effective operation without sacrificing reliability. This parameter flexibility allows the system to optimize between cost and performance based on actual usage patterns.
2Power
If conventional internal combustion engines are used, then mechanical power generation is achieved, but noise, vibration, and emissions are increased
Solution Approach 1:
The patent replaces the traditional mechanical crankshaft-connecting rod mechanism with a magnetic coupling system. This substitution eliminates mechanical friction and contact, significantly reducing noise and vibration while maintaining power generation capability. The magnetic coupling directly transfers rotational motion from the engine to the generator without mechanical intermediaries.
Solution Approach 2:
The patent changes the operational parameters of the internal combustion engine by optimizing combustion efficiency and operating conditions. This reduces harmful emissions while maintaining adequate power output. The remote control system also enables optimization of engine parameters based on actual load requirements, preventing unnecessary emissions from running at suboptimal conditions.
3Ease of operation
If fixed mechanical settings are used on the generator, then simple control is maintained, but the generator cannot adapt to varying downstream demand
Solution Approach 1:
The patent implements a feedback control system where the control unit continuously monitors downstream demand and automatically adjusts generator power output accordingly. This closed-loop feedback mechanism maintains ease of operation (no manual intervention needed) while providing excellent adaptability to varying demands. The system self-regulates based on real-time conditions.
Solution Approach 2:
The generator performs self-adjustment of power output based on monitored demand conditions. The control unit autonomously manages power level changes without requiring user intervention, combining operational simplicity with adaptive capability. This self-service approach resolves the contradiction between simple control and adaptability.
