Motor Coil Temperature Sensor Holder for Stable Contact Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor designs require complex structures and processes for mounting temperature sensors, leading to increased costs, manufacturing complexity, and vulnerability to damage from vibrations or external impacts.
Innovation Solution
A motor design that integrates a temperature sensor directly onto the coil using a sensor holder, eliminating the need for separate jigs and bonding agents, and providing elastic support to maintain stable contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a temperature sensor is mounted on the coil using a separate jig and bonding agent, then the sensor can be fixed to the coil, but the structure and manufacturing process become complicated and manufacturing costs increase
Solution Approach 1:
The patent integrates the temperature sensor mounting function directly into the holder structure by providing a sensor holding portion formed as an integral part of the holder. This eliminates the need for separate jigs and bonding agents, simplifying both the structure and manufacturing process while maintaining reliable sensor attachment.
Solution Approach 2:
The holder structure is designed to inherently provide the sensor holding function through its own geometry, specifically the sensor holding portion that engages with the temperature sensor. The holder serves multiple functions simultaneously: supporting the terminal and mounting the sensor, without requiring external assistance from separate components or processes.
2Reliability
If a bonding agent is used to fix the temperature sensor to the coil, then the sensor can be secured, but the manufacturing process becomes more complex and time-consuming
Solution Approach 1:
The patent replaces the chemical bonding mechanism (bonding agent) with a mechanical engagement system. The sensor holding portion of the holder provides a mechanical interface that secures the temperature sensor through physical engagement, eliminating the need for bonding agents and associated curing processes.
Solution Approach 2:
The patent extracts and eliminates the bonding agent from the sensor mounting process. By designing the holder with an integrated sensor holding portion, the solution removes the unnecessary element (bonding agent) that complicates the manufacturing process, achieving both simplification and improved productivity.
3Manufacturing precision
If a separate jig is used to support the temperature sensor during assembly, then the sensor can be positioned accurately, but the assembling process becomes more complex
Solution Approach 1:
The holder is pre-designed with an integrated sensor holding portion that inherently provides the positioning function. This preliminary design eliminates the need for separate positioning jigs during assembly, as the holder itself is prepared in advance to guide and secure the sensor in the correct position.
Solution Approach 2:
The holder is designed as a multi-functional component that simultaneously serves as a terminal support structure and a sensor mounting mechanism. The sensor holding portion is integrated into the holder, allowing a single component to perform multiple functions without requiring separate specialized tools or jigs.
