External Antenna Handle Layout for Wireless Food Temperature Probes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless food temperature probes face issues with signal interference, positional deviations, and limited antenna size due to the metal handle structure and cavity design, leading to inconsistent signal transmission and increased complexity.
Innovation Solution
An integrated antenna handle with a metal antenna placed on the outer surface of a ceramic handle body, protected by an enamel layer, which isolates it from internal wires and allows for larger, more complex designs, ensuring consistent installation and improved transmission capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the antenna is placed inside the handle cavity, then the handle structure is compact, but the metal handle causes signal shielding and interference
Solution Approach 1:
The patent extracts the antenna from the internal cavity structure and relocates it to the external surface of the handle. This extraction eliminates the shielding effect caused by the metal handle and internal wires, while the antenna remains functionally integrated into the handle through magnetic attachment or embedding in non-metallic portions.
2Reliability
If the antenna is fixed by threading or structural installation, then the antenna can be secured to the probe body, but positional deviations occur during installation
Solution Approach 1:
The patent applies preliminary action by pre-positioning the antenna on the handle surface before final assembly. The antenna is either magnetically pre-attached or embedded in a predetermined location on the handle exterior, ensuring consistent positioning without requiring precise threading or adjustment during final assembly.
3Volume of moving object
If the cavity structure is used for antenna placement, then the antenna fits within the handle, but the antenna size is limited and layout complexity increases
Solution Approach 1:
The patent transitions from three-dimensional internal cavity placement to two-dimensional surface mounting on the handle exterior. This dimensional change allows the antenna to be positioned on the outer surface where space is abundant, enabling larger antenna sizes and simpler layout without constraining the internal cavity for power lines and sensor wires.

AI summary
An integrated antenna handle and a wireless food temperature probe are provided. The integrated antenna handle of the present disclosure includes a handle body, a metal antenna is provided on an outer wall of the handle body, and a protective layer is provided on an outer wall of the handle body and covers the metal antenna. The integrated antenna handle is the first in the field of temperature measurement handles to achieve an external placement of the metal antenna on the outside of the handle, thus breaking through physical limitations of the handle on the metal antenna. The metal antenna is physically isolated from the power lines and sensor wires inside the outer wall of the handle body. The handle body can also be made of non-metallic materials, thereby greatly reducing the signal interference or shielding of the metal antenna.
