Solution Overview

Problem

Conventional shower flow rate controllers can only provide a single outlet flow rate, limiting users' ability to choose preferred flow rates, and are not easily adjustable during use.

Innovation Solution

A flow rate controller design featuring a rotatable member with second flow holes of different sizes that can overlap a first flow hole, allowing for adjustable water flow rates by rotating the member to various positions, enabling users to adjust the flow rate with one hand.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional controller with single outlet flow rate is used, then the device structure is simple, but the adaptability is limited and users cannot choose multiple flow rates

Engineering Contradiction:
Improveflow rate optionsVSAvoidcontroller structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The controller is segmented into multiple functional components: a control body with multiple flow rate adjustment mechanisms, each independently adjustable. This allows the single device to provide multiple flow rate options (improving adaptability) while keeping each individual adjustment mechanism relatively simple (managing device complexity)

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The controller is designed as a multi-functional device that can provide different flow rates for different outlets simultaneously. The control body incorporates multiple adjustment mechanisms that work together to deliver customized flow rates to multiple outlets, making the device universally applicable for various shower preferences

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If a conventional controller requiring two hands for adjustment is used, then the control precision may be adequate, but the ease of operation is poor during shower use

Engineering Contradiction:
Improvecontroller adjustmentVSAvoidflow rate control accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The controller incorporates dynamic adjustment mechanisms that can be operated with one hand during shower use. The control assembly includes movable components that respond to single-handed manipulation, making the device dynamically adaptable to the user's operational context while maintaining adequate control precision

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If multiple flow holes with different sizes are introduced, then the flow rate adjustability is improved, but the device complexity increases

Engineering Contradiction:
Improveflow rate adjustment rangeVSAvoidcontrol assembly structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Different flow holes with specific size characteristics are positioned at different locations within the control assembly. Each flow hole is designed with specific local properties (size, position) to control flow rates at different outlets, providing diverse flow rate adjustment range while organizing complexity through functional localization

Inventive Principle:
Principle #3Local quality

AI summary

A flow rate controller (1) includes a pipe body (10) and a control assembly. The pipe body (10) includes a channel, a water supply opening (161) and a water outlet opening (121), wherein the water supply opening (161) is adapted to connect to a water supply pipe, and the water supply opening (161) communicates with the water outlet opening (121) through the channel. The control assembly includes a fixed member (26) and a rotatable member (22), wherein the fixed member (26) is fixedly positioned in the pipe body (10), and includes a first flow hole (262). The rotatable member (22) is coaxially and rotatably connected to the pipe body (10), so that the rotatable member (22) is rotatable relative to the pipe body (10). The rotatable member (22) includes a plurality of second flow holes (222) and a plurality of adjusting positions, wherein the second flow holes (222) have different hole sizes to each other, and each of the adjusting positions is respectively corresponding to the corresponding one of the second flow holes (222). When the rotatable member (22) rotates to one of the adjusting positions, the corresponding second flow hole (222a, 222b, 222c or 222d) overlaps the first flow hole (262).
