Cooking and baking device with seamlessly-jointed griddle plates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking and baking devices with griddle plates have a large gap between them when rotated, leading to material loss and difficulty in cleaning, as the plates are not seamlessly jointed, causing debris and oil to enter the device and potentially damaging its internal structure.
Innovation Solution
A cooking and baking device with seamlessly-jointed griddle plates, where the upper and lower housings are hinged with chambers and a connecting passage, allowing the griddle plates to align closely, reducing the gap between them to less than 5 mm, and featuring an elastic part for interference fit and enhanced sealing, along with a fastener system for removable connection and displacement control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If griddle plates are arranged far from the rotation axis in existing devices, then the housings can be connected by the rotation axis, but this causes a larger gap between the two griddle plates when rotated to a tiled position
Solution Approach 1:
The patent changes the spatial arrangement by moving the rotation axis from a peripheral position to a central position between the griddle plates. This dimensional repositioning allows the griddle plates to be arranged closer to the axis, enabling them to align seamlessly when the housings are rotated to a tiled position, thereby reducing the gap between plates while maintaining the housing connection structure.
Solution Approach 2:
The patent employs asymmetric arrangement of components around the rotation axis. The griddle plates are positioned at specific distances from the centrally-located rotation axis, creating an asymmetric layout that optimizes the alignment and minimizes gaps during rotation, rather than using a symmetric peripheral arrangement.
2Device complexity
If griddle plates are positioned far from the rotation axis, then the housing structure is simplified, but materials easily fall on positions outside the griddle plates during covering
Solution Approach 1:
By repositioning the rotation axis to the center and bringing griddle plates closer to it, the patent changes the spatial configuration so that the griddle plates extend closer to the outer edges of the housings. This dimensional adjustment ensures that materials remain confined on the griddle plates during covering operations, preventing material loss while maintaining housing structural simplicity.
3Device complexity
If griddle plates are not seamlessly jointed, then the device structure is simpler, but debris and oil enter the device making it difficult to clean and potentially damaging internal structure
Solution Approach 1:
The patent extracts the rotation axis from the griddle plate assembly area and positions it centrally between the plates. This separation allows the griddle plates to be arranged edge-to-edge without the axis interfering with their seamless joint, creating a cleanable configuration where debris and oil cannot enter the internal structure while maintaining manufacturing simplicity.
Solution Approach 2:
By changing the spatial arrangement to have the rotation axis between rather than within the griddle plate assembly, the patent creates a seamless joint configuration. This dimensional reorganization eliminates gaps where debris could accumulate, making the device easy to clean while avoiding complex joint structures.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device prevents material loss during closing, enhances sealing for easy cleaning and durability, and reduces the risk of damage by ensuring a tight, seamless joint between the griddle plates, thus prolonging the device's service life.
Implementation Method 1
at least one of the upper housing and the lower housing is internally provided with an elastic part upwards jacking the griddle plates

AI summary
Disclosed is a cooking and baking device with seamlessly-jointed griddle plates, including an upper housing, a lower housing hinged with the upper housing, chambers in the upper housing and the lower housing, griddle plates arranged within the chambers, and a connecting passage communicating with the chambers. Ends of the griddle plates in the upper housing and the lower housing are aligned in the connecting passage, an axis along which the upper housing and the lower housing are rotated is located between the griddle plates of the upper housing and the lower housing, and the axis is arranged to be not higher than top surfaces of the griddle plates. In use, the two griddle plates are tightly engaged, and thus food materials placed therein will not fall out during baking, the service life of the cooking and baking device is prolonged.
