Solution Overview
Problem
Conventional air conditioner compressors face challenges in accurately detecting outlet temperature due to separate holder structures for the temperature sensor and hanging device, leading to inaccurate temperature measurement.
Innovation Solution
A combined fixing bracket integrates the temperature sensor mounting and hoist hanger structure, allowing the sensor to directly contact the compressor's surface for precise temperature detection, while also reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate holder structures are used for mounting the temperature sensor and hanging device, then the device complexity is reduced, but the temperature measurement precision deteriorates
Solution Approach 1:
The patent combines the temperature sensor holder and hanging device into a single integrated holder structure. The holder includes a body portion that mounts the temperature sensor and a hanging portion that extends from the holder body to receive the hoist hook, eliminating the need for separate mounting structures while enabling both functions through unified design.
Solution Approach 2:
The holder structure serves multiple functions simultaneously: it acts as a mounting structure for the temperature sensor, provides a hanging point for the hoist through the extended hanging portion, and maintains structural integrity during compressor installation and transportation. This multi-functional design reduces the number of components needed.
2Measurement precision
If the temperature sensor is spaced apart from the compressor surface, then the device complexity is reduced, but the temperature detection accuracy deteriorates
Solution Approach 1:
The holder body is designed to position the temperature sensor in direct contact with the compressor discharge port surface. The integrated structure eliminates gaps and spacing issues that would occur with separate mounting, ensuring accurate temperature detection while maintaining structural simplicity.
3Ease of manufacture
If a combined fixing bracket is used, then the manufacturing cost is reduced, but the device complexity increases
Solution Approach 1:
The holder is designed as a single integrated component that combines the sensor mounting function and hanging function. This unified structure reduces the total number of parts that need to be manufactured, assembled, and inventoried, thereby lowering manufacturing costs despite the increased functional complexity of the single component.
Solution Approach 2:
By designing the holder to perform multiple functions (sensor mounting and hanging), the patent eliminates the need for separate components, reducing overall part count and assembly steps. This multi-functionality approach simplifies the manufacturing process and reduces costs while maintaining necessary functionality.

AI summary
An outdoor unit of an air conditioner may include a compressor having a power terminal and a discharge port that protrudes from an upper surface thereof, and a fixing bracket coupled at a point on the upper surface of the compressor that is spaced apart from the power terminal and the discharge port. The fixing bracket may be provided with a hanging hole to which a hoist may be hooked and a sensor holder on which a temperature sensor may be mounted.
