Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sink dividers fail to effectively seal and remain stable under water pressure, often slipping or becoming dislodged due to inadequate sealing and instability.
Innovation Solution
A detachable sink divider system with expandable bladders pressurized by a pressurization apparatus, utilizing suction cups, retainer arms, and a support frame to create stable compartments, featuring a one-way valve and pressure relief mechanism to maintain a seal and prevent overpressurization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing sink dividers are used to separate sink compartments, then the sink can be divided into sections, but the dividers fail to effectively seal and remain stable under water pressure, often slipping or becoming dislodged
Solution Approach 1:
The patent employs a flexible bladder made of elastic material that can expand and contract. The bladder is inserted into a retaining structure and pressurized with fluid to expand, creating a tight seal against the sink wall. This flexible membrane approach allows the divider to conform to the sink surface while maintaining sealing effectiveness under water pressure, directly resolving the contradiction between sealing effectiveness and stability.
Solution Approach 2:
The patent uses fluid pressure (pneumatics or hydraulics) to inflate the bladder and create the sealing force. A pressurization device introduces fluid into the bladder, causing it to expand and press against the sink wall with sufficient force to maintain a watertight seal. This hydraulic/pneumatic mechanism provides the necessary holding force to prevent the divider from slipping or becoming dislodged under water pressure.
2Ease of operation
If a sink divider is made detachable for easy installation and removal, then ease of operation is improved, but the divider may become dislodged or unstable when subjected to water pressure
Solution Approach 1:
The patent employs a dynamic retention system where the bladder can be inflated or deflated on demand. When installation or removal is needed, the bladder is deflated to reduce its diameter, allowing easy insertion into or removal from the retaining structure. Once in place, the bladder is inflated to expand and create a secure, stable seal that resists water pressure. This dynamic state change enables both ease of operation and reliable attachment.
Solution Approach 2:
The patent changes the physical parameter of the bladder (its diameter or volume) to control its retention characteristics. By varying the amount of fluid in the bladder, the user can transition between a compact state for easy installation/removal and an expanded state for secure attachment and stable sealing under water pressure.
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 system provides a stable, watertight separation of sink compartments by using expandable bladders and retainer arms, ensuring effective water retention and secure attachment to the sink, preventing dislodgment and maintaining a tight seal.
Implementation Method 1
A sink divider system may include a suction cup retainer that is configured with a suction cup that detachably attached to the sink wall or base to further secure the sink divider in place.
Implementation Method 2
expandable bladders that are pressurized by a pressurization apparatus to press the bladder against the wall of the sink to create a seal between a first portion of the sink and a second portion of the sink
Implementation Method 3
The bladder may be an elastic material that expands when pressurized and retracts when the pressure is removed, such as rubber, or natural rubber, or a synthetic elastomer or polymeric elastomer
Implementation Method 4
The sink divider may also have a pair of retainer arms that are spring deployed to press a retainer stop against the wall of the sink to further stabilize and support the sink divider within the sink

AI summary
A sink divider is detachably attachable across a sink to form a first and second compartment of the sink. The sink divider has an expandable bladder that is pressurized by a pressurization apparatus to press the bladder against the wall of the sink to create the two compartments. The pressurization apparatus includes a plunger that plunges fluid from a pressure receptacle into the bladder. A pressure valve may be fluidly coupled with the interior of the bladder to release fluid when the pressure in the bladder exceeds a threshold pressure. The sink divider may also have a pair of retainer arms that are spring deployed to press a retainer stop against the wall of the sink to further stabilize and support the sink divider within the sink.
