Innovation Solution

Implementing an electronically controlled electromagnetic lock with a control system and RFID proximity detection for keyless operation, eliminating movable handles and ensuring secure, temperature-controlled access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional mechanical locking mechanism with movable handles is used, then the container can be locked and unlocked, but the movable parts are prone to wear and failure

Engineering Contradiction:
Improvelocking mechanism reliabilityVSAvoidservice life of movable parts
Core Design Contradiction:
ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent replaces the traditional mechanical locking mechanism with an electromagnetic locking system. The electromagnetic lock uses magnetic fields to secure the door, eliminating movable mechanical handles and latches that are prone to wear. The control system activates the electromagnetic lock through electrical signals, providing a wear-free, reliable locking mechanism that addresses both the reliability and durability requirements.

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

Solution Approach 2:

The invention removes the troublesome movable handle and mechanical latch components from the locking system. By extracting these wear-prone mechanical elements and replacing them with an electromagnetic actuation system, the patent eliminates the source of wear while maintaining the essential locking and unlocking functionality through contactless electromagnetic engagement.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If an electronically controlled electromagnetic lock with RFID proximity detection is implemented, then wear is reduced and security is enhanced, but the device complexity increases

Engineering Contradiction:
Improvelocking mechanism durabilityVSAvoidcontrol system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The control system integrates multiple functions into a single unified unit: RFID proximity detection for contactless authentication, electromagnetic lock actuation for secure locking, and control signal management. This multi-functional integration reduces the need for separate components and simplifies the overall system architecture despite the advanced capabilities provided.

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

AI summary

There is provided herein an aircraft galley container (2A) including an enclosure housing (4A), a door (6A), an electronically controlled lock (12A) and a control system (16A, 18A). The enclosure housing (4A) defines a cavity within the enclosure housing (4A; 4B; 4C). The door (6A) is moveable between an open position and a closed position. In the closed position, the door (6A) closes and seals the cavity. Control system (16A, 18A) is configured to selectably place the electronically controlled lock (12A) in a locked mode and an unlocked mode, wherein in the locked mode, the door (6A) is prohibited from opening and in the unlocked mode, the door (6A) is able to open. An aircraft galley system is also provided.
