Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temperature measuring probes face issues with poor connection stability between metallic and non-metallic portions of the probe shell, leading to disengagement during long-term use.
Innovation Solution
A Bluetooth temperature measuring probe with improved mounting stability, featuring a locking assembly that includes a locking member, locking nut, and limiting nuts to securely connect the handle to the needle tube, ensuring high stability and preventing detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If close fitting and insertion method is used to connect metallic portion and non-metallic portion, then the structure is simple and easy to manufacture, but the connection stability is poor and components easily disengage during long-term use
Solution Approach 1:
The connection structure is divided into multiple functional components: a locking member with locking protrusions, a locking groove for engagement, and a limiting groove for positional constraint. This segmentation allows each component to perform its specific function, achieving both ease of manufacture and reliable connection through modular assembly.
Solution Approach 2:
The locking member acts as an intermediary element between the metallic portion and non-metallic portion. It features locking protrusions that engage with the locking groove to prevent disengagement, while the limiting groove constrains its position. This intermediary component resolves the contradiction by providing a simple yet effective connection mechanism that ensures long-term stability.
2Reliability
If locking assembly with multiple components is used to connect handle to needle tube, then the connection stability is high and detachment is prevented, but the device complexity increases
Solution Approach 1:
The locking member integrates multiple functions into a single component: it provides locking through protrusions that engage with the locking groove, positional constraint through the limiting groove, and guidance during assembly. This merging of functions reduces the number of separate components needed, achieving high mounting stability without excessive device complexity.
Solution Approach 2:
The locking assembly is designed for self-aligning and self-locking during assembly. The locking protrusions automatically engage with the locking groove when components are brought together, and the limiting groove self-constrains the locking member's position. This self-service mechanism eliminates the need for complex adjustment procedures or additional fastening operations.

AI summary
The present application relates to the technical field of thermodetector, and discloses a high stability Bluetooth temperature measuring probe, including a needle tube having a hollow mounting chamber, a handle configured to abut against a tail end of the needle tube, a first thermal sensor positioned in the mounting chamber of the needle tube close to the head end, an antenna mounted inside the needle tube and electrically connected to the first thermal sensor, and a locking assembly configured for connecting the handle to the needle tube. The locking assembly includes a locking member, a locking nut and a limiting nut, in which the limiting nut is connected to the antenna and is configured to limit the locking member; and an inner wall of the needle tube is defined with a locking slot; the locking nut is in thread connection with the antenna; the locking nut abuts against the handle at one end thereof away from the needle tube; and when the locking member is snapped into the locking slot, the handle is abutted against a tail end of the needle tube by the locking nut. The temperature measuring probe and the needle tube of the present application has high connection stability, and the problem of easy detaching between the ceramic handle and the needle tube can be effectively solved.
