Removable Heating Plate Design for Filled Brioche Uniform Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waffle-making devices with fixed heating plates lack a system for rocking movement, leading to uneven heat transfer and potential filling leakage when preparing filled brioches, especially those with frozen substances, due to non-uniform dough distribution and incomplete plate contact.
Innovation Solution
The device features removable heating plates with releasable elastic fastening elements and loaded elastic elements that ensure optimal contact with heat transfer plates, allowing for relative shifting and improved thermal contact, along with independent thermostatic control for each plate assembly to ensure uniform heating and prevent filling leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If heating plates are fixed to subassemblies without rocking movement capability, then device structure is simple, but heat transfer uniformity deteriorates and filling leakage occurs
Solution Approach 1:
The heating plate is designed with a rocking movement capability through a pivot point, allowing it to dynamically adjust its position. This dynamic adjustment ensures optimal contact between the heating plate and the dough surface, maintaining uniform heat transfer across the entire heating surface while accommodating variations in dough distribution.
Solution Approach 2:
The device incorporates a spring-loaded mechanism that applies preliminary force to press the heating plate against the dough before heating begins. This preliminary action ensures complete contact between the heating plate and the dough surface, preventing filling leakage while the rockable design maintains heat transfer uniformity throughout the heating process.
2Ease of operation
If heating plates are made removable for cleaning, then ease of operation improves, but reliability of thermal contact may deteriorate
Solution Approach 1:
The heating plate is designed as a separate, removable component that can be easily detached from the subassembly for cleaning and maintenance. The segmentation allows the heating plate to be removed without affecting the underlying heat transfer plate and thermal resistor assembly, while the rockable mounting ensures reliable thermal contact when reinstalled.
Solution Approach 2:
A heat transfer plate serves as an intermediary component between the removable heating plate and the fixed thermal resistor. This intermediary ensures consistent thermal contact even when the heating plate is removed and reinstalled, as the heat transfer plate remains in place and maintains the thermal pathway.
3Adaptability or versatility
If heating plates are made rigid without shifting capability, then structural stability is maintained, but adaptability to different brioche shapes deteriorates
Solution Approach 1:
The heating plate incorporates a rocking movement mechanism that allows it to dynamically adjust its orientation and position. This dynamic capability enables the rigid plate structure to adapt to different brioche shapes and sizes while maintaining stable thermal contact throughout the heating process.
Solution Approach 2:
The rockable mounting allows the heating plate to change its angular position and contact pressure parameters. This parameter adjustment enables the same rigid plate to effectively accommodate various brioche geometries by optimizing its orientation and contact surface for each specific shape.

AI summary
A device (1) for heating filled brioches preferably filled with ice-cream, comprising an upper subassembly (3) and a lower subassembly (4) linked by one or more joints or hinges (10). Each one of the subassemblies (3, 4) includes a heating plate (14) with a cavity (14a) intended to receive the filled brioche, or other similar product, in order to heat it, arranged so that in an operative position they overlap one another. Each heating plate (14) is positioned on top of a heat transfer plate (16) enclosed in a thermoinsulating layer (13), except for an opening to allow contact between the heating plate (14) and the heat transfer plate (16).The heating plates (14) are releasable from the subassembly (3, 4) on which they are arranged by means of one or more releasable fastening elements protruding from the heating plate (14) and inserted in one or more slots (3c, 4c) of either casing of the subassemblies (3, 4).
