Solution Overview
Problem
The temperature sensor in compressors is prone to loosening due to a weak mounting structure, leading to distorted temperature data and potential failures such as wear of the pump body and demagnetization of the motor.
Innovation Solution
A housing assembly with a fixing bracket that includes a top plate and side plates forming a trapezoidal shape, an opening slot, and a mounting cavity to securely attach the temperature sensor to the compressor housing, ensuring accurate temperature detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple mounting structure is used for the temperature sensor, then the device complexity is reduced, but the reliability deteriorates due to loosening and falling off
Solution Approach 1:
The mounting structure is divided into a fixing bracket with connection portions and a separate fixing portion that interfaces with the temperature sensor. This segmentation allows the connection portions to be firmly fixed to the housing while the fixing portion provides a dedicated, simplified interface for the temperature sensor, resolving the contradiction between simplicity and reliability.
Solution Approach 2:
The fixing bracket acts as an intermediary component between the temperature sensor and the housing. It provides a stable mounting platform with connection portions that attach to the housing, while the fixing portion creates a reliable interface for the temperature sensor without requiring complex direct attachment to the housing.
2Reliability
If the temperature sensor is firmly fixed to prevent loosening, then the reliability is improved, but the ease of operation deteriorates due to difficulty in installation and maintenance
Solution Approach 1:
By segmenting the mounting structure into a fixed bracket portion and a removable fixing portion, the temperature sensor can be easily installed and maintained by simply detaching the fixing portion, while the connection portions remain firmly fixed to the housing, thus maintaining reliability.
Solution Approach 2:
The mounting structure incorporates dynamic characteristics where the fixing portion can be easily attached and detached from the fixing bracket, allowing for simple installation and maintenance operations, while the connection portions maintain a stable, fixed connection to the housing.
3Ease of operation
If the temperature sensor is loosely mounted, then the ease of operation is improved for installation, but the measurement precision deteriorates due to distorted temperature data
Solution Approach 1:
The fixing bracket serves as an intermediary that provides a stable, precise mounting interface for the temperature sensor. The fixing portion creates a reliable connection between the sensor and the bracket, ensuring accurate temperature detection while keeping the overall installation process simple.
Solution Approach 2:
The mounting structure utilizes spatial arrangement with connection portions at different locations on the housing to create a stable three-dimensional mounting framework. This dimensional approach ensures the temperature sensor is firmly positioned for accurate measurement while maintaining installation simplicity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures the temperature sensor remains tightly attached, providing accurate temperature measurements for precise compressor control, preventing failures like pump body wear and motor demagnetization.
Implementation Method 1
The opening slot is formed on the top plate to increase elasticity to allow the top plate to press against the temperature sensor
Implementation Method 2
The temperature sensor abuts an outer wall of the housing

AI summary
A housing assembly, a compressor, and an air conditioner are provided. The housing assembly has a housing, a temperature sensor, and a fixing bracket. The temperature sensor abuts an outer wall of the housing. The fixing bracket has a fixing portion and connection portions located on two sides of the fixing portion. Each connection portion is fixedly connected to the housing. A mounting cavity is formed between the fixing portion and the housing. The fixing portion has an inlet end for mounting the temperature sensor in the mounting cavity, and a top plate and two side plates connected to two sides of the top plate. An angle between the top plate and each of the two side plates is an obtuse angle. An opening slot facing away from the inlet end is formed on the top plate and is offset from a centerline of the top plate.
