Solution Overview

Problem

Residential sink and shower water valves are often within reach of small children, leading to accidental water overflow, scalding, and drowning risks, particularly when caregivers are not present.

Innovation Solution

A sink and shower handle restraint system comprising cuffs and elongated elements that securely lock sink and shower handles in place, preventing them from being turned to undesired positions, thereby preventing accidents.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If sink and shower handles are made accessible for normal operation, then ease of operation is improved, but safety risks increase due to accidental activation by children

Engineering Contradiction:

Improvehandle accessibilityVSAvoidaccidental activation risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary restraint device consisting of cuffs and elongated elements that physically block handle rotation. The cuffs wrap around the handles and are connected by elongated elements, creating a mechanical barrier that prevents children from turning the handles while allowing authorized adults to operate them by manipulating the restraint mechanism.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The restraint system is divided into separate modular components: individual cuffs for each handle and connecting elongated elements. This segmentation allows the restraint to be applied to one or both handles independently and enables easy installation and removal while maintaining safety functionality.

Inventive Principle:

Principle #1Segmentation

2Object-affected harmful factors

If restraint devices are installed on handles, then safety is improved by preventing accidental activation, but device complexity increases

Engineering Contradiction:

Improveaccidental activation preventionVSAvoidrestraint system structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The cuffs are designed as flexible bands that can be easily wrapped around handles of various sizes and shapes. This flexibility simplifies the overall device structure compared to rigid restraint mechanisms, while still providing effective blocking functionality. The flexible material allows the cuffs to conform to different handle geometries without requiring complex adjustment mechanisms.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The restraint device incorporates dynamic elements that allow it to adapt to different handle configurations. The flexible cuffs and elongated connecting elements can be positioned and adjusted to match various sink and shower handle arrangements, maintaining safety effectiveness across different applications without requiring multiple specialized devices.

Inventive Principle:

Principle #15Dynamics

AI summary

Systems and methods are provided herein for restraining sink and shower handles. In a first aspect of a sink handle restraint, a first sink handle cuff fits over a first sink handle of a sink faucet, and a second sink handle cuff fits over a second sink handle of the sink faucet. The first sink handle cuff and second sink handle cuff slide along an elongated element that locks the first sink handle cuff and second sink handle cuff into place, preventing the first and second sink handles from being rotated into an “on” position.
