Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If threaded connection is used to connect nozzle body and nozzle core seat, then connection strength is improved, but installation complexity increases and sealing reliability deteriorates
Solution Approach 1:
The connection structure is segmented into a nozzle body with an accommodating through hole and a nozzle core seat with a cam mechanism. The cam structure allows for simple insertion and rotation operations while maintaining strong connection through the cam's geometric shape that locks into the accommodating through hole.
Solution Approach 2:
The complex threaded connection structure is extracted and replaced with a simplified cam-based connection mechanism. The cam structure eliminates the need for multi-turn rotation and tightening operations while maintaining adequate connection strength through its geometric locking action.
2Strength
If threaded connection is used to connect nozzle body and nozzle core seat, then connection strength is improved, but sealing reliability deteriorates
Solution Approach 1:
An annular rubber ring is introduced as an intermediary sealing element between the nozzle body and nozzle core seat. This rubber ring deforms under compression to fill gaps and create reliable sealing, preventing water leakage while allowing for simple cam-based connection without complex threading.
Solution Approach 2:
The annular rubber ring utilizes the flexibility of elastomeric material to adapt to the connection interface between the nozzle body and core seat. The rubber ring's ability to deform and recover ensures consistent sealing pressure and reliable water-tight connection.
3Strength
If threaded connection is used, then connection strength is improved, but installation time increases
Solution Approach 1:
The cam structure is pre-formed with the geometric shape that provides both connection and locking functions. During installation, the nozzle core seat is simply inserted into the accommodating through hole and rotated, allowing the pre-designed cam geometry to automatically establish the connection without requiring multiple adjustment steps.
Solution Approach 2:
Instead of using a traditional threaded connection where the male thread is rotated into the female thread, the invention inverts the approach by using a cam structure that is inserted and then rotated to lock into place. This reversal of the connection sequence simplifies the installation process while maintaining connection strength.
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 design simplifies installation by eliminating complex rotation and tightening operations, while the annular groove and rubber ring combination enhances sealing performance, resulting in a more effective and user-friendly massage nozzle experience.
Implementation Method 1
the annular rubber ring arranged on the nozzle core seat is squeezed and compressed; when the annular rubber ring is pressed to the annular groove arranged on the nozzle body, the annular rubber ring returns to its original shape and expands into the annular groove

AI summary
An easy-to-install bathtub massage nozzle includes a nozzle body and a nozzle core seat. The nozzle core seat is inserted through an accommodating through hole of the nozzle body, and then the nozzle core seat is pressed, so that an annular rubber ring on the nozzle core seat is squeezed and compressed. When pressed to an annular groove on the nozzle body, the annular rubber ring returns to its original shape and expands into the annular groove, so that the nozzle core seat and the nozzle body can be tightly connected. The bathtub massage nozzle greatly simplifies the installation process, and users only need to insert and press easily to complete the installation without complicated rotation and tightening operations. In addition, the combination of the annular groove and the annular rubber ring also effectively improves the sealing performance, so that the water outlet effect is improved.
