Solution Overview

Problem

Existing drain safety devices require manual operation, which exposes operators to hazardous substances, are cumbersome to operate individually, and lack simultaneous control capabilities.

Innovation Solution

An automatic and/or automated drain safety device with a remote control mechanism, utilizing a closure assembly and actuating assembly that includes a sealing disc movable between closed and release positions, operated pneumatically or hydraulically, allowing remote actuation without direct contact and muscular effort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If manual operation of drain safety devices is used, then the device structure remains simple, but operators are exposed to hazardous substances and must exert muscular strength

Engineering Contradiction:
Improveexposure to hazardous substancesVSAvoiddevice structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical operation with an automated actuating assembly that uses electrical or electronic control mechanisms. The closure assembly is actuated automatically without requiring operators to physically manipulate valves or covers, thereby eliminating exposure to hazardous substances while introducing controlled system complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an intermediate actuating mechanism that mediates between the operator and the closure assembly. This intermediary system transmits the closing action remotely, allowing operators to initiate closure without direct contact with hazardous materials in the drain area.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If individual manual operation of each drain safety device is required, then device simplicity is maintained, but operating time and efficiency decrease

Engineering Contradiction:
Improveoperating efficiencyVSAvoidoperating time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent merges multiple drain safety devices into a coordinated system where the actuating assembly can control multiple closure assemblies simultaneously or sequentially. This consolidation allows operators to manage several drains through a single control interface, significantly improving productivity and reducing the time required to address multiple drainage issues.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The actuating assembly is designed with universal control capabilities that can operate different types of closure assemblies across multiple drains. This multi-functional design enables a single control system to handle various drainage scenarios, reducing operational time and enhancing overall system efficiency.

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

3Ease of operation

If remote control actuation is implemented, then operator safety is improved, but device complexity and cost increase

Engineering Contradiction:
Improveoperator convenienceVSAvoidcontrol system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical remote control mechanisms with simpler electrical or electronic actuation systems. This substitution maintains operator convenience and safety while reducing the mechanical complexity that would otherwise be required for reliable remote operation over distances.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
