Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held shower heads with dual water outlet modes face issues such as unnecessary splashes and safety hazards due to the large flushing force, and require a lengthy assembly process for rotatable connections, increasing labor costs.
Innovation Solution
A hand-held shower head design featuring a fixing element, a rotating element, and a spring mechanism that allows for automatic switching between flushing and spraying modes, preventing water from the first outlet channel from being active initially, ensuring safer operation and reducing assembly time through a simpler connection method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the shower head is designed with two water outlets perpendicular to each other for flushing and spraying respectively, then both flushing and spraying functions are achieved, but the device complexity increases and assembly time is longer
Solution Approach 1:
The rotating element integrates both flushing and spraying functions into a single component structure. The water outlet cover serves as both a protective cover and a rotating switch mechanism that controls water flow distribution, allowing one component to perform multiple functions and reducing overall device complexity
Solution Approach 2:
The patent combines the water outlet cover, rotating switch, and flow control mechanisms into an integrated assembly. The fixing element and rotating element are merged into a compact unit where the rotating element's rotation directly controls the switching between flushing and spraying modes, simplifying the overall structure while maintaining dual functionality
2Adaptability or versatility
If the rotating element is manually switched to flushing mode, then flushing function is activated, but safety hazards occur if the user forgets to switch back to spraying mode
Solution Approach 1:
The system automatically returns to the safe spraying mode after the flushing operation is completed. The rotating element's design allows it to automatically rotate back to the spraying position when the flushing mode is deactivated, eliminating the need for manual intervention and preventing safety hazards from forgotten mode switches
Solution Approach 2:
The spring mechanism provides automatic feedback control by pushing the rotating element back to the spraying position after flushing mode activation. This mechanical feedback system ensures the device returns to a safe state automatically, preventing harmful splashes and electrical hazards without requiring user awareness or action
3Adaptability or versatility
If the water outlet cover is rotatably connected to the body, then mode switching is enabled, but the assembly process takes longer time and labor cost increases
Solution Approach 1:
The rotating element is pre-assembled with the water outlet cover and positioning structures during manufacturing. The spring mechanism and rotating connection are pre-configured in the correct positions, allowing for rapid final assembly without requiring complex alignment or multiple assembly steps, thereby reducing assembly time and labor costs
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 prevents unnecessary splashes and safety hazards by ensuring the flushing mode is not active initially, and simplifies assembly by allowing a single operation to establish the rotational connection, thus reducing labor costs and enhancing user safety.
Implementation Method 1
the first spring elastically recovers and drives the rotating element to rotate to a second position

AI summary
A hand-held shower head includes a fixing element, a rotating element and a first spring. The fixing element is provided with a water inlet channel and a first water outlet channel for flushing water. The rotating element is rotatably connected with the fixing element and is provided with a water passage and a second water outlet channel for spraying water. The first spring is disposed between the fixing element and the rotating element. When the rotating element rotates to a first position, the water passage communicates with the water inlet channel and the first water outlet channel, and the first spring is elastically deformed. When the rotating element is released from the first position, the first spring elastically recovers to drive the rotating element to rotate to a second position, and the second water outlet channel communicates with the water inlet channel.
