Temperature-sensor fixing device and compressor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing temperature-sensor fixing device suffers from deformation and movement of the spring fixing part, which narrows the attachment opening, making it difficult to reattach the temperature sensor due to the spring moving out of place.
Innovation Solution
The temperature-sensor fixing device incorporates a plate spring with a first bent portion forming an acute angle between the pressing plate and the connecting plate, positioned to face the edge of the sensor holder, preventing deformation and movement that blocks the opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metal plate fixing part is used to secure the temperature sensor, then the temperature sensor can be firmly fixed, but the fixing part deforms and moves out of place when the temperature sensor is attached, causing the attachment opening to narrow
Solution Approach 1:
The fixing part is designed as a spring mechanism that can dynamically adjust its position. The spring expands when the temperature sensor is inserted, providing firm fixation, and contracts to allow easy removal without permanent deformation or blocking the attachment opening.
Solution Approach 2:
The spring constant and geometric parameters of the fixing part are optimized to control the expansion and contraction behavior. By adjusting the spring parameters, the fixing part provides sufficient holding force during attachment while ensuring it returns to its original position after sensor removal, preventing opening narrowing.
2Reliability
If the fixing part serves as a spring to secure the temperature sensor, then the temperature sensor can be held in place, but the fixing part deforms during attachment, causing movement out of place and blocking the opening
Solution Approach 1:
The spring-based fixing part dynamically responds to the attachment process by expanding to secure the sensor and then contracting to return to its precise original position, maintaining position accuracy and preventing opening blockage.
Solution Approach 2:
The spring mechanism is pre-designed with appropriate pre-compression and elastic properties to cushion the deformation during sensor attachment. This beforehand cushioning ensures the fixing part absorbs the attachment forces without permanent deformation or position shift.

AI summary
A temperature-sensor fixing device is a temperature-sensor fixing device for fixing a temperature sensor to a measured object. The temperature-sensor fixing device includes a sensor holder and a plate spring. The sensor holder defines, when the sensor holder is fixed on the measured object, a tubular body with an opening provided at each end. The sensor holder accommodates the temperature sensor inside the sensor holder. The plate spring is attached to the sensor holder and configured to hold the temperature sensor in place. The plate spring has a pressing plate, a fixed plate, a connecting plate, and a first bent portion. The pressing plate is configured to press the temperature sensor against the measured object. The fixed plate is configured to clamp the sensor holder between the fixed plate and the pressing plate. The connecting plate extends between one end of the pressing plate and one end of the fixed plate. The first bent portion is located between the pressing plate and the connecting plate, and bent to form an acute angle between the pressing plate and the connecting plate. The first bent portion is positioned to face an edge of the sensor holder that defines the opening from which the temperature sensor is to be inserted into the sensor holder.
