Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baking devices face inefficiencies in heat conduction due to gaps between griddle plates and heating elements caused by pressure springs, leading to uneven heating and increased energy consumption, with existing fixing mechanisms being unstable and posing safety risks.
Innovation Solution
A griddle plate suspension assembly featuring a housing, griddle plate, and heating element connected by a fastener with an elastic part, a lever, and a stopper, allowing for close fitting and uniform heating, with a tension spring and pressure spring arrangement for stable and efficient heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a pressure spring is arranged between the griddle plate and the heating element to fix their locations, then the heating element can be pressed against the griddle plate, but a gap between the griddle plate and the heating element is inevitable due to the middle elastic extruding of the pressure spring, which reduces heat conducting performance and increases energy consumption
Solution Approach 1:
The patent removes the pressure spring from the system entirely and replaces it with a suspension mechanism using tension springs that hang the heating element from the housing. This extraction eliminates the elastic extrusion problem that created gaps and energy loss, while maintaining adequate contact pressure through the weight-based suspension system.
Solution Approach 2:
Instead of pushing the heating element upward against the griddle plate with a pressure spring, the patent inverts the approach by suspending the heating element downward from the housing using tension springs. This inversion allows the heating element to naturally contact the griddle plate without elastic deformation, eliminating the gap problem.
2Strength
If a pressure spring is arranged between the griddle plate and the heating element, then the heating element can be pressed against the griddle plate, but it is difficult to keep the heating element and the griddle plate to be mutually parallel, resulting in uneven heat distribution
Solution Approach 1:
The patent uses multiple tension springs distributed at different locations to suspend the heating element, rather than a single pressure spring. This segmentation allows each spring to independently maintain contact pressure at its location, ensuring the heating element remains parallel to the griddle plate and achieving uniform heat distribution.
3Reliability
If a fixing mechanism with a spring is used to retain the griddle plate, then the griddle plate can be fixed in place, but when the griddle plate is removed, the heating part can easily bounce upward and out of the housing, and when the fixing mechanism is loosened, the spring is released causing the heating part and griddle plate to bounce together, bringing danger to the user
Solution Approach 1:
The patent inverts the spring arrangement from a pushing mechanism to a suspending mechanism. The tension springs hang the heating element from the housing rather than pushing it upward. When the griddle plate is removed, the heating element simply hangs down under gravity and spring tension, eliminating the bouncing hazard entirely.
Solution Approach 2:
The tension springs provide an upward counteracting force that balances the weight of the heating element, keeping it suspended in a controlled position. This anti-weight mechanism prevents the heating element from bouncing upward or outward, ensuring safety when the griddle plate is removed or during operation.
