Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the valve and sensor are connected through a threaded fastener, then the connection is secure and reliable, but the installation process becomes complex and time-consuming requiring additional tools
Solution Approach 1:
The valve assembly is divided into separate components (valve body, sensor assembly, locking mechanism) that can be independently manufactured and assembled. The locking mechanism is segmented into movable locking elements that engage with slots in the sensor assembly, allowing for tool-free attachment while maintaining secure connection.
Solution Approach 2:
The valve assembly incorporates a self-locking mechanism where the locking elements automatically engage with the sensor assembly slots upon insertion, eliminating the need for external tools like torque wrenches. The design enables the components to secure themselves through their own structural features.
2Strength
If traditional threaded fasteners are used to connect valve and sensor, then the connection strength is sufficient, but the installation time increases and additional tools are required
Solution Approach 1:
The locking mechanism employs movable locking elements that can dynamically transition between engaged and disengaged states. During installation, the locking elements automatically move into the slots of the sensor assembly, providing immediate mechanical interlocking without requiring time-consuming threading operations.
Solution Approach 2:
The locking mechanism serves as an intermediary element between the valve body and sensor assembly. This intermediate component facilitates quick connection by providing pre-formed engagement features (slots and locking elements) that eliminate the need for threaded fasteners while maintaining connection strength.
3Reliability
If threaded fasteners are used for valve and sensor connection, then the assembly is secure, but the device complexity and cost increase due to requiring torque wrenches
Solution Approach 1:
The valve assembly incorporates a self-locking mechanism where the locking elements automatically engage with the sensor assembly slots upon insertion, eliminating the need for external tools like torque wrenches. The design enables the components to secure themselves through their own structural features.
Solution Approach 2:
The invention extracts the locking function from separate external tools (torque wrenches and threaded fasteners) and integrates it directly into the valve assembly structure. The locking elements are built-in components that perform the securing function without requiring external intervention or specialized tools.

AI summary
The invention relates to the field of tire pressure detection technologies, and discloses a tire pressure sensor including: a valve assembly including a mounting portion and an elastic telescopic structure mounted to the mounting portion, the elastic telescopic structure elastically extending and retracting on at least one side of the mounting portion; a sensor assembly having two opposite clamping surfaces, at least one of the two clamping surfaces being provided with a locking hole, the mounting portion being located between two of the clamping surfaces, and the elastic telescopic structure being inserted into the locking hole. After the elastic telescopic structure is shortened, the mounting portion of the valve assembly may be inserted between the two clamping surfaces. When the mounting portion of the valve assembly is located between the two clamping surfaces, the elastic telescopic structure may be extended and inserted into the locking hole automatically, so that the valve assembly and the sensor assembly may be installed conveniently, and no additional tools are required.
