Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If diesel driven electrical generators are used for aircraft starting and service, then power supply capability is sufficient, but pollution is generated and fuel replenishment is required
Solution Approach 1:
The patent replaces the diesel-driven mechanical generator system with an electric battery system. The battery system eliminates the mechanical combustion engine, thereby eliminating exhaust emissions and pollution while providing sufficient electrical power for aircraft starting and service operations.
Solution Approach 2:
The invention extracts and removes the diesel engine component from the power supply system, keeping only the essential electrical power generation and storage functions through battery systems. This extraction eliminates the harmful combustion byproducts while maintaining the necessary power output.
2Duration of action of stationary object
If diesel driven electrical generators are used for aircraft starting and service, then continuous power supply is achieved, but constant fuel replenishment and spill cleanup are required
Solution Approach 1:
The battery system is designed to be self-contained with onboard charging capabilities. The system can recharge its own batteries using external power sources or aircraft electrical systems, eliminating the need for external fuel delivery and manual replenishment operations.
Solution Approach 2:
The system incorporates battery replacement and recharging cycles where depleted batteries are swapped or recharged. This allows continuous operation without the logistical burden of fuel management, as batteries can be quickly replaced or recharged without the complexity of fuel handling.
3Device complexity
If a single battery system is used for both starting and service, then device complexity is reduced, but battery capacity requirements increase
Solution Approach 1:
The patent divides the power system into two separate battery systems: a starting battery for engine cranking and a service battery for auxiliary power during ground operations. This segmentation allows each battery to be optimized for its specific function, preventing the need for an oversized single battery that would be required to handle both high-current starting and extended service operations.
Solution Approach 2:
The system dynamically switches between the starting battery and service battery based on operational requirements. The starting battery provides high current bursts for engine starting, while the service battery handles sustained lower-power demands during ground servicing, optimizing power delivery without requiring excessive total capacity.

AI summary
A start/service aircraft battery system including a housing on wheels/dolly for convenient movement to a space adjacent an aircraft to be started/serviced. An electrical output cable is carried by the housing and attachable to the aircraft to be started/serviced. A control panel on the housing includes a start/service switch having a start position and a service position. A starting battery and a larger service battery are carried by the housing, the starting battery being coupled to the electrical output cable through the start/service switch in the start position and the larger service battery being coupled to the electrical output cable through the start/service switch in the service position. The starting battery is removably attached to the start/service aircraft battery system for individual starting operations.
