Solution Overview

Problem

Traditional sinks and bathtubs lack effective water blocking devices, leading to water splashing that can make surrounding areas greasy or slippery, increasing cleaning difficulty and slipping risks.

Innovation Solution

A water blocking member comprising a fixed plate rotatably connected to a water baffle plate, locked and fixed through various locking devices such as straps, hook and loop fasteners, or suction cups, to prevent water splashing by positioning the baffle plate perpendicularly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional sinks and bathtubs are made of materials such as stainless steel, iron enamel, or ceramic, then the structural strength and durability are improved, but the water blocking capability deteriorates

Engineering Contradiction:
Improvestructural strengthVSAvoidwater splashing
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The water blocking member is divided into multiple functional segments: a fixed plate for stable installation, a rotatable water baffle plate for adjustable positioning, and a locking device for securing the structure. This segmentation allows each component to perform its specific function optimally while collectively solving the water splashing problem without compromising structural strength.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The water baffle plate is designed to be rotatable relative to the fixed plate, allowing dynamic adjustment of the baffle angle to optimize water blocking effectiveness for different water flow conditions. The locking device enables the structure to transition from a dynamic adjustable state to a fixed stable state during operation, combining both adaptability and structural integrity.

Inventive Principle:
Principle #15Dynamics

2Object-affected harmful factors

If a water blocking device is added to prevent water splashing, then the water blocking capability is improved, but the device complexity increases

Engineering Contradiction:
Improvewater splashingVSAvoiddevice complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The water blocking function is extracted as a separate, independent device that can be installed in traditional sinks and bathtubs without modifying their original structure. This extraction approach allows the water blocking capability to be added while maintaining the simplicity of the original sink or bathtub design, avoiding unnecessary complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of making the entire sink or bathtub structure complex to achieve water blocking, the invention inverts the approach by adding a simple, separate water blocking member that attaches to the existing structure. This reverses the traditional design philosophy and achieves water blocking with minimal added complexity.

Inventive Principle:
Principle #13The other way round (Inversion)

3Stability of the object's composition

If the water baffle plate is fixed in position, then the structural stability is improved, but the adaptability to different water flow conditions deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidadaptability to water flow
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The water baffle plate incorporates rotational movement capability around the fixed plate, allowing the baffle angle to be adjusted dynamically. This dynamic feature enables the structure to adapt to different water flow conditions and directions while the locking device maintains structural stability during use by securing the baffle plate in the desired position.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The key parameter that can be changed is the angle of the water baffle plate relative to the fixed plate. By allowing this angular parameter to be adjusted and then locked, the system achieves both adaptability to different water flow conditions and structural stability during operation.

Inventive Principle:
Principle #35Parameter changes

4Reliability

If multiple locking mechanisms are used to secure the water baffle plate, then the reliability of water blocking is improved, but the ease of operation deteriorates

Engineering Contradiction:
Improvewater blocking reliabilityVSAvoidease of adjustment
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The locking device is designed to be self-operating through simple user actions. The snap-in members automatically engage with the clamping members when the water baffle plate is rotated to the desired position, providing reliable locking without requiring complex mechanisms or multiple steps. The structure itself facilitates the locking action.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The locking mechanism uses simple, inexpensive components such as snap-in members and clamping members that can be easily manufactured and replaced if needed. These simple components provide reliable locking functionality without the complexity and cost of sophisticated locking systems.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

AI summary

A water blocking member includes a fixed plate, a water baffle plate and a locking device. The fixed plate is rotatably connected to the water baffle plate. The water baffle plate and the fixed plate are locked and fixed through the locking device, and the locking devices configured to lock an angle between the water baffle plate and the fixed plate. Through the above structure, a user can fixedly place the fixed plate in a sink or a bathtub or any other position platform that requires water blocking. Under the locking action of the locking device, the water baffle plate is rotated to a locking position relative to the fixed plate. The water baffle plate is locked in a basically perpendicular state relative to the fixed plate.
