Oven Door Interspace Placement for Wireless Sensor Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ovens face issues with overheating and limited wireless communication due to the placement of receiving or transceiving elements, which can lead to damage and restricted positioning, affecting the quality of temperature monitoring and control during baking.
Innovation Solution
Positioning the receiving or transceiving element within the interspace between two walls or panes of the oven door, shielded by the door printing, allows for easy access, maintenance, and optimal wireless communication throughout the chamber, enabling bidirectional signal transmission and reducing the risk of overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the receiving or transceiving element is integrated into the baking chamber wall or lighting device, then wireless communication can be established, but the component is exposed to high temperatures causing overheating and damage
Solution Approach 1:
The receiving or transceiving element is extracted from the high-temperature baking chamber environment and relocated to the door structure, specifically positioned in an interspace between door walls or panes. This spatial separation removes the communication component from the harmful thermal environment while preserving its wireless communication function with sensors inside the chamber.
Solution Approach 2:
The door structure serves as an intermediary medium that enables wireless communication between the external control system and internal sensors without exposing the communication element to high temperatures. The door acts as a protective barrier and transmission medium, allowing signal passage while isolating the receiving element from thermal damage.
2Object-affected harmful factors
If the receiving or transceiving element is placed in a recess of the baking chamber wall, then it is protected from direct exposure, but the recess dimensions limit the antenna size, shape and position affecting wireless communication quality
Solution Approach 1:
The solution transitions from constraining the receiving element within a two-dimensional recess of the chamber wall to utilizing the three-dimensional interspace within the door structure. This additional spatial freedom allows for optimized antenna dimensions, shapes and positions that enhance wireless communication reliability without compromising protection.
Solution Approach 2:
The door structure is segmented into multiple walls or panes creating an interspace that accommodates the receiving element. This segmentation provides both protection similar to a recess and sufficient room for optimal antenna configuration, resolving the conflict between protection and communication quality.
3Reliability
If the receiving or transceiving element is positioned inside the baking chamber, then wireless communication can be established, but the component is difficult to access for maintenance and cleaning
Solution Approach 1:
The receiving or transceiving element is extracted from the interior of the baking chamber and relocated to the door structure. This extraction maintains wireless communication capability with sensors inside the chamber while providing easy accessibility from the exterior for maintenance, cleaning and replacement of the communication component.
4Ease of repair
If the receiving or transceiving element is mounted on the door, then it is easily accessible for maintenance, but it may impair the aesthetics of the oven
Solution Approach 1:
The receiving element is positioned in a specific local area of the door - the interspace between walls or panes - which is less visually prominent. This localized placement maintains ease of access for maintenance while minimizing aesthetic impact on the overall door appearance.
Solution Approach 2:
The door printing or decorative elements serve as an intermediary that visually conceals or integrates the receiving element into the door's aesthetic design. The printing acts as a camouflage layer that preserves the visual appearance while allowing the communication component to function and remain accessible.
