Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If propane or butane heater systems are used for portable cooking, then adequate heating capability is provided, but safety hazards arise due to open flames
Solution Approach 1:
The patent replaces the mechanical combustion system (propane/butane burners) with an electrical heating system. A heating element is integrated into the base of the cooking vessel, powered by a battery pack, eliminating open flames while maintaining heating capability. The electrical heater provides controlled thermal energy directly to the liquid in the vessel.
Solution Approach 2:
The patent combines the cooking vessel and power supply into a single integrated unit. The battery pack is permanently mounted in the base of the vessel, merging the container and power source functions. This integration eliminates the need for separate fuel containers and burners, reducing safety hazards while maintaining portability.
2Weight of moving object
If integrated heating vessel and battery assembly are combined, then portability is improved, but device complexity increases
Solution Approach 1:
The patent merges the battery pack and cooking vessel into a single integrated assembly. The battery pack is permanently mounted in the base of the vessel with electrical connections pre-established, eliminating the need for separate carrying and connection of power sources. This integration simplifies the user experience despite the increased internal complexity.
Solution Approach 2:
The integrated design serves multiple functions: the battery pack provides power for heating, the base structure serves as both structural support and battery mounting platform, and the electrical connections enable automatic power delivery. This multi-functionality reduces the number of separate components needed.
3Stability of the object's composition
If connector carriage is extendable for engagement, then operational stability is improved, but device complexity increases
Solution Approach 1:
The connector carriage is designed to be extendable and retractable, changing its configuration based on operational needs. During use, the carriage extends to engage with the cooking vessel for stable operation. When not in use, it retracts to minimize protrusion. This dynamic adjustment provides stability when needed while reducing complexity in storage.
Solution Approach 2:
The connector system is divided into separate components: the carriage body, the electrical contacts, and the engagement mechanism. This segmentation allows each component to be optimized independently and simplifies the overall assembly and disassembly process.

AI summary
An electronic stove incorporates a cylindrical outer shell (14) and a concentric copper heater core (80). A foil heater (84) surrounds the copper heater core and a heater control PCB (72) carried in the outer shell is connected to the foil heater. A battery assembly (40) has a cylindrical second outer shell (42) carrying a battery pack (44). A power controller (70) carried in the second outer shell is connected to the battery pack. A connector carriage (52) is engaged between the battery assembly and cylindrical outer shell, extending through the shell of the battery assembly and received in the cylindrical outer shell aligned proximate a lower surface of the first outer shell whereby the lower surfaces of the first outer shell and the second outer shell are in planar alignment. A first contact set (74) of a connector is connected to the heater control PCB. A second contact set (76) is connected to the power controller.
