Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tilting bratt pans used in professional kitchens are heavy, bulky, difficult to clean, have long heating and cooling times, and lack precise control over cooking power, especially for low-heat cooking, while being energy-intensive.
Innovation Solution
A tilting bratt pan design featuring a frame with a pivotally mounted cooking tank and induction heating, where an electrical frequency control generator supplies voltage to an induction coil within the tank, accompanied by a tilting mechanism and a removable tray with a spout for easy emptying, and integrated fans and filters for efficient heating and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If electric or gas heating means are used, then heating capability is provided, but heating and cooling times are long and energy consumption is high
Solution Approach 1:
The patent replaces traditional electric resistance or gas heating systems with induction heating technology. The induction coil generates an electromagnetic field that directly induces eddy currents in the conductive cooking vessel, heating the food directly rather than heating the vessel first. This substitution of heating mechanism dramatically reduces energy loss and heating time while enabling faster cooling when the power is interrupted.
Solution Approach 2:
The induction heating system operates by generating electromagnetic fields that cause rapid phase changes in the heating process - quickly transitioning from cold to hot and from hot to cool when power is interrupted. The electromagnetic field can be turned on and off instantaneously, enabling rapid thermal phase transitions that conventional heating systems cannot achieve.
2Measurement precision
If traditional electric or gas heating means are used, then heating is provided, but precise adjustment of cooking power especially for low-heat cooking is not possible
Solution Approach 1:
The patent incorporates a control unit that receives signals from a sensor detecting the temperature of the cooking vessel or food, and adjusts the power supplied to the induction coil accordingly. This closed-loop feedback system enables precise control of cooking power, particularly for low-heat cooking requirements, by continuously monitoring temperature and making real-time adjustments to maintain the desired cooking conditions.
Solution Approach 2:
The induction heating system provides dynamic control of heating power through electronic modulation of the electromagnetic field intensity. The control unit can rapidly adjust the power level from very low to very high settings, enabling precise control for different cooking stages and requirements, particularly for delicate low-heat cooking that is difficult to achieve with traditional heating systems.
3Ease of operation
If the tank is pivotally mounted with tilting means, then emptying capability is provided, but the device becomes heavy and bulky
Solution Approach 1:
The patent extracts the heavy motorized tilting mechanism from the cooking tank assembly and relocates it to a separate support box structure. The cooking tank itself remains relatively lightweight and simple, while the tilting function is provided by a separate actuation system mounted on the frame. This separation reduces the weight and complexity of the moving cooking vessel while maintaining the emptying capability.
Solution Approach 2:
The patent uses a simplified tilting mechanism that replicates the essential emptying function without requiring a complex motorized system. The tilting means can be a simple mechanical linkage or hydraulic cylinder that provides the necessary tilt angle for emptying, copying the functional effect of more complex systems with reduced weight and complexity.

AI summary
The device has a cooking or frying vessel (5) comprising a parallelepiped box (9) that includes side walls (11-14) on an upper edge to which a removable cooking tray (15) is supported. Two of the side walls have axles supported on a bearing secured to vertical columns (2a, 2b). One of the columns comprises an electric frequency control generator to generate an electric voltage transmitted by a power supply cable to an induction coil in the box such that axle of electromagnetic flow generated by the coil is directed toward a tray interior. The axles are hollow to allow passage of the cable.
