Elastic Temperature Sensor Holder for Damage-Free Motor Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temperature sensor holders require damaging the insulator flange to remove them, leading to inefficient motor replacement when only the sensor needs to be replaced.
Innovation Solution
A temperature sensor holder with a sensor holding portion, holder engagement portion, and an arm with a curved portion that allows elastic engagement and disengagement, distributing stress evenly to prevent damage during mounting and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the temperature sensor holder is removed by bending the flange to displace the step, then the tab of the holder fixing portion can be disengaged from the step, but the flange may be damaged due to stress concentration on the base end
Solution Approach 1:
The holder fixing portion is divided into a separate removable component that engages with the flange through elastic deformation of the arm, rather than being integrally fixed. This segmentation allows the holder to be detached without damaging the flange, as the engagement and disengagement occur through controlled elastic deformation of the arm's curved portion rather than forced bending of the flange.
Solution Approach 2:
The arm is designed with a curved portion that provides elastic deformation capability, transforming the static rigid connection into a dynamic flexible connection. This allows the holder to be easily mounted and removed by elastically deforming the curved portion, distributing stress away from the flange and preventing damage while maintaining secure engagement during operation.
2Reliability
If the temperature sensor holder uses a rigid connection with tabs engaged on steps, then the holder is securely fixed, but the removal process requires damaging the flange
Solution Approach 1:
The rigid tab-step connection is replaced with a dynamic elastic connection through the curved portion of the arm. The holder maintains reliable fixation during operation through elastic force, but can be easily removed by elastically deforming the curved portion, eliminating the need to damage the flange for removal.
Solution Approach 2:
The connection mechanism changes from a rigid geometric fit (tab on step) to an elastic force-based connection. The curved portion of the arm stores and releases elastic energy, providing secure fixation during normal operation while allowing easy removal when needed, thus changing the fundamental parameter of connection rigidity to flexibility.
3Reliability
If the temperature sensor holder is designed for secure engagement with the insulator, then the temperature sensor is reliably held, but the insulator flange may be damaged during removal
Solution Approach 1:
The holder fixing portion is designed as a separate removable component that interfaces with the insulator flange through the elastic arm, rather than being permanently fixed. This allows the temperature sensor to be replaced without damaging the insulator, as the holder can be detached by elastically deforming the arm.
Solution Approach 2:
The elastic arm with curved portion acts as an intermediary between the holder and the insulator flange. It provides secure engagement during operation while absorbing the stress of removal, preventing direct transmission of damaging forces to the insulator flange.

AI summary
A temperature sensor holder with which it is possible to easily mount a temperature sensor without giving damage on an object to which the temperature sensor is mounted, etc., includes a sensor holding portion that holds the temperature sensor; a holder engagement portion that is to be engaged with an object; and an arm having a curved portion that connects the sensor holding portion and the holder engagement portion. A temperature sensor mounting method for easily mounting the temperature sensor to a motor without giving damage on the motor includes engaging the holder engagement portion with an insulator due to elastic force of the curved portion of the arm of the temperature sensor holder, and at the same time, bringing the temperature sensor into pressure contact with a stator coil by the sensor holding portion to mount the temperature sensor holder to the insulator.
