Solution Overview

Problem

Inconsistent or incorrect installation of door components, such as emergency exit doors and fire doors, can pose safety risks, including failure to open or remain closed during emergencies, and compromised access control systems.

Innovation Solution

A method involving a pre-configured door system type selection process using an electronic configuration system, which provides pre-configured technical data for installing door components, ensuring compatibility and safety by selecting door system types that match user specifications and reducing installation errors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual installation of multiple door components is performed without pre-configuration, then installation flexibility is maintained, but installation consistency and safety reliability deteriorate due to human error and component mismatch

Engineering Contradiction:
Improveinstallation consistencyVSAvoidinstallation process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-configuring door system types in a database before installation. The electronic configuration system retrieves pre-defined door component combinations based on door characteristics, eliminating the need for installers to manually determine component compatibility. This pre-planning ensures consistent and safe installations while reducing on-site complexity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an electronic configuration system as an intermediary between the installer and the door components. This system acts as a mediator that automatically retrieves appropriate door system types from a database based on input parameters, ensuring correct component selection without requiring the installer to have expert knowledge of component compatibility.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If pre-configured door system types are provided from a database, then installation consistency and safety are improved, but installation time and configuration complexity increase

Engineering Contradiction:
Improvesafety complianceVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies universality by creating door system types that can be reused across multiple installations. The database stores universal door component configurations that can be retrieved and applied to different doors based on their characteristics. This multi-functional approach allows the same pre-configured system types to serve multiple purposes and locations, reducing overall installation time while maintaining safety compliance.

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

3Adaptability or versatility

If door components are selected without pre-configuration, then installation adaptability is maintained, but component compatibility and system reliability deteriorate

Engineering Contradiction:
Improvecomponent compatibilityVSAvoidinstallation ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies parameter changes by using door-specific parameters (such as door characteristics) as input to retrieve appropriate pre-configured door system types from the database. The system automatically adjusts the component configuration based on these parameters, ensuring compatibility while simplifying the installation process. This parameter-driven approach maintains adaptability to different door types while improving ease of operation.

Inventive Principle:
Principle #35Parameter changes
