Oven device for preparing a dough product, method for displaying an ideal temperature range of an oven device and use of an oven device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pizza ovens lack precise measurement of the oven stone temperature, which is crucial for successful pasta preparation, as current temperature sensors are affected by heat radiation and can only measure interior temperatures.
Innovation Solution
A sensor device is positioned between the housing wall and the underside of the oven stone, resiliently attached via a spring mechanism, allowing for accurate measurement of the oven stone's temperature without interference from heat radiation, and a second sensor measures interior temperature, with a display device showing ideal temperature ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If temperature sensors are placed inside the oven interior to measure temperature, then the interior temperature can be monitored, but the oven stone temperature cannot be accurately measured due to heat radiation interference
Solution Approach 1:
The temperature sensor is extracted from the oven interior environment and repositioned to contact the oven stone directly from the exterior side. This removes the sensor from the harmful heat radiation field while maintaining its ability to measure the stone's temperature through direct thermal contact.
Solution Approach 2:
The oven stone itself serves as an intermediary medium. Instead of measuring the interior air temperature directly, the sensor measures the stone's temperature, which has already been heated by conduction from the interior. The stone acts as a thermal mediator that transfers heat information from the cooking environment to the sensor without exposing the sensor to direct radiation.
2Measurement precision
If the sensor device is attached directly to the oven stone surface, then temperature measurement is possible, but the sensor may be damaged during stone removal or installation
Solution Approach 1:
A resilient element (spring or elastomer) is introduced between the sensor housing and the oven stone surface. This cushioning element absorbs mechanical shocks and impacts that occur during stone installation and removal, protecting the fragile sensor components from damage while maintaining reliable thermal contact.
Solution Approach 2:
The sensor housing incorporates a resilient element that provides flexible, compliant contact with the oven stone surface. This flexible connection allows the sensor to maintain intimate thermal contact with the stone while accommodating stone irregularities and absorbing mechanical stresses without rigid bonding.
3Area of stationary object
If the oven stone is made large to provide sufficient cooking surface area, then more pasta can be prepared, but the stone becomes heavier and harder to handle
Solution Approach 1:
The oven stone is divided into two separate components: a large cooking surface plate and a smaller handle attachment. This segmentation allows the cooking surface to remain large for adequate cooking area while the handle can be optimized for ergonomic gripping and easy maneuvering, separating the functional requirements of cooking surface and handling.
Solution Approach 2:
The handle is attached to the oven stone at the periphery rather than requiring the entire stone to be lifted. This dimensional change in handling approach allows users to grip and maneuver the stone by a small portion rather than supporting the full weight and size of the large cooking surface.
