Microbubble Shower Head Using Swirl Flow Without a Spray Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shower heads without a water spray plate fail to generate micro bubbles effectively from tap water, leading to inadequate shower feeling and ease of use, as they often require external air intake and pressurization, and are prone to injury or damage due to their design.
Innovation Solution
A shower head design featuring a micro bubble generator with a tornado plate and pressing plate, integrated into a body with a cap, which generates micro bubbles from tap water without external air intake, using a micro bubble generation path with a narrowing and expanding cone shape to increase flow speed and create cavitation, ensuring the device is easy to hold and assemble.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a water spray plate is removed to simplify structure, then ease of manufacture is improved, but shower feeling quality deteriorates
Solution Approach 1:
The invention changes the physical parameters of water flow by creating a narrowing water passage that increases flow speed, transforming the water discharge characteristics to achieve spray effect without a spray plate
Solution Approach 2:
The invention uses hydraulic principles by narrowing the water passage to increase flow speed and generate spray discharge, utilizing fluid dynamics to replace the traditional spray plate structure
2Device complexity
If micro bubbles are generated without external air intake to simplify structure, then device complexity is reduced, but micro bubble generation effectiveness deteriorates
Solution Approach 1:
The micro bubble generator uses the kinetic energy of the flowing water itself to generate micro bubbles, without requiring external air intake systems. The water flow creates cavitation and micro bubbles through the narrowing passage design
Solution Approach 2:
The invention uses hydraulic energy of the water flow to generate micro bubbles through cavitation in the narrowing passage, converting kinetic energy into bubble formation without external air supply
3Speed
If flow speed is increased through narrowed passage to generate spray, then shower feeling is improved, but water pressure loss increases
Solution Approach 1:
The invention uses a dynamically designed narrowing passage that gradually decreases in size to optimize flow acceleration while minimizing energy loss, creating spray discharge efficiently
4Ease of manufacture
If a tubular object without spray plate is used, then ease of manufacture is improved, but safety deteriorates due to injury risk
Solution Approach 1:
The invention divides the head unit into multiple components (body, bottom plate, pressing plate, cap) that can be assembled to create a safer structure with integrated spray generation, separating the spray generation function from a traditional spray plate
