Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the valve spool set is directly disposed in the overhead shower head main body, then the switching function is achieved, but the structure becomes complicated and occupies large space
Solution Approach 1:
The patent extracts the valve spool set from the overhead shower head main body and relocates it to a separate valve chamber. This separation removes the complex switching mechanism from the main body, simplifying its structure while maintaining the switching function through the remote operation component in the hand shower head.
Solution Approach 2:
The patent introduces a water pressure-mediated switching mechanism where water pressure differential acts as an intermediary to drive the valve spool movement. Instead of direct mechanical linkage, the system uses pressure differential created by the operation component to remotely control the valve spool position, reducing structural complexity.
2Ease of operation
If the valve spool set is directly disposed in the overhead shower head main body, then the switching function is achieved, but it occupies large space
Solution Approach 1:
The valve spool set is extracted from the overhead shower head main body and placed in a dedicated valve chamber, reducing the space required in the main body while maintaining the switching function through remote operation.
Solution Approach 2:
The valve spool is nested within the valve chamber, and the operation component is integrated into the hand shower head. This nested arrangement optimizes space utilization by placing components in dedicated chambers rather than distributing them throughout the main body.
3Ease of operation
If a pendulum bar linkage is used to achieve linkage between switches, then switching is achieved, but the structure becomes complicated
Solution Approach 1:
The patent replaces the mechanical pendulum bar linkage system with a fluid-pressure-based switching mechanism. Water pressure differential, controlled by an operation component in the hand shower head, drives the valve spool to switch between positions, eliminating complex mechanical linkages while maintaining switching functionality.
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 the structure, enhances user convenience by allowing easy adjustment of outlet angles and damping forces, and improves operational accuracy through unequal water pressure acting on sealing and hydro portions to drive the valve spool.
Implementation Method 1
when the cam (63) rotates and couples to the gradient section, the friction between the suspending sheet (64) and the rotation block (62) changes to achieve the adjusting of the damping
Implementation Method 2
the area of the water flowing acts on the sealing portion and that acts on the hydro portion (45) are unequal, the on-off of the second diversion waterway (13) makes the water pressure unequal to the sealing portion (44) and the hydro portion (45) so as to drive the valve spool to slide
