Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Electrically operated folding partitions pose a risk of injury or death when individuals are trapped between moving partitions, and unauthorized users can operate these partitions despite safety features, lacking comprehensive protection in critical areas and user authentication.

Innovation Solution

Implement a biometric verification system to authenticate authorized users by recording and comparing biological traits, ensuring only trained and authorized individuals can operate the partitions, and preventing operation if authentication fails.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If electrically operated folding partitions are used to automatically open and close partitions, then productivity and ease of operation are improved, but safety deteriorates due to risk of injury or death when persons become trapped between partitions

Engineering Contradiction:

Improveautomation of partition operationVSAvoidrisk of injury or death

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary actions by detecting the presence of a person in the critical area before the partition begins to move. The optical detection device identifies persons in the hazardous zone ahead of time, allowing the control system to prevent activation of the partition motor, thereby avoiding the harmful effect before it can occur.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

An optical detection device acts as an intermediary between the control system and the partition mechanism. This intermediary detects persons in the critical area and transmits information to the control system, which then decides whether to allow partition operation, thus mediating the interaction between automated operation and safety protection.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If conventional key-based access control is used, then ease of operation is maintained, but reliability deteriorates because keys can be lost or obtained by unauthorized users

Engineering Contradiction:

Improveaccess control simplicityVSAvoidauthorization security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces the mechanical key-based access control system with an optical biometric verification system. Instead of using physical keys that can be lost or stolen, the system uses optical detection devices to capture and verify biometric characteristics (such as facial recognition, fingerprint, or iris patterns), providing a more reliable form of authorization that cannot be easily replicated or lost.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If biometric verification system is implemented, then reliability and safety are improved by preventing unauthorized operation, but device complexity increases

Engineering Contradiction:

Improveuser authentication securityVSAvoidsystem structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The control system is designed with multi-functionality, serving both as the authorization verification unit and the operational control unit. The same control system that manages partition movement also processes biometric verification results, eliminating the need for a completely separate authorization device and thereby reducing overall system complexity despite the added biometric functionality.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The optical detection device serves as an intermediary that captures biometric data and provides verification information to the control system. This intermediary approach allows the complex biometric verification process to be isolated in a dedicated component, making the overall system more modular and manageable despite the increased complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Object-affected harmful factors

If safety devices are added to detect persons in critical areas, then safety is improved, but device complexity and cost increase

Engineering Contradiction:

Improveprotection from injuryVSAvoidsystem structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The optical detection device performs multiple functions: it serves as both the safety device for detecting persons in critical areas and as the verification device for biometric authentication. This multi-functionality reduces the need for separate safety detection systems, thereby limiting the increase in device complexity while maintaining improved safety protection.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A method for maintaining a folding operable wall comprising: (a) recording a template of a biological trait of an authorized individual into a biometric verification system; (b) saving the template in a database; (c) capturing a new record; (d) comparing the new record against the template; (e) confirming the identity of the authorized individual if the new record is substantially similar to the saved template; (f) preventing the electrical operation circuit from functioning if the biometric verification system fails to authenticate the identity of the authorized individual; and (g) restarting the electrical operation circuit after the identity of the authorized individual is verified.
