Solution Overview

Problem

Existing storage containers in vehicles, such as aircraft, face challenges with securing large objects due to strong forces during flight, which can cause the mattress to shift and inadvertently open or close the storage container, and there is a need for reliable visual and tactile cues to indicate the container is safely locked.

Innovation Solution

A storage container design with a latching assembly and locking mechanism that includes a latching actuator and lock actuator, biased toward the released position, providing secure locking and visual/tactile feedback, capable of withstanding forces up to 9G, and allowing the top to be selectively movable between closed and opened positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of stationary object

If a storage container is provided in the base of a bed to maximize storage space, then storage capacity is improved, but the mattress must be lifted to access the storage container which complicates operation

Engineering Contradiction:
Improvestorage capacityVSAvoidaccess to storage container
Core Design Contradiction:
Volume of stationary objectVSEase of operation

Solution Approach 1:

The storage container is segmented into a base and a top that can be independently moved. The top can be lifted separately from the base, allowing access to storage compartments without requiring the entire mattress to be lifted. This segmentation enables selective access to different storage areas while maintaining the integrated bed structure.

Inventive Principle:
Principle #1Segmentation

2Volume of stationary object

If a storage container is provided in an aircraft bed, then storage capacity is improved, but strong forces during flight can push down the mattress and inadvertently close the storage container

Engineering Contradiction:
Improvestorage capacityVSAvoidstorage container locking
Core Design Contradiction:
Volume of stationary objectVSReliability

Solution Approach 1:

The latching assembly is designed with a latch that automatically engages when the top is in the closed position, preventing inadvertent closing. The lock actuator can be positioned in an actuated state that maintains the top in a selectively movable position, ready for quick access while preventing accidental closure during flight forces.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The locking mechanism uses a lock actuator with two positions (actuated and released) that changes the mechanical state of the latching assembly. When actuated, it allows selective movement; when released, it prevents movement entirely. This parameter change enables the system to adapt to different operational requirements during flight.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If a locking assembly is added to prevent inadvertent opening or closing, then reliability is improved, but the device complexity increases

Engineering Contradiction:
Improvestorage container lockingVSAvoidlatching and locking assembly
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The latching assembly and locking assembly are merged into an integrated system where the latch and lock actuator work together. The lock actuator controls the state of the latch, combining two functions (latching and locking) into a coordinated mechanism that reduces overall complexity compared to separate independent systems.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The latching assembly is designed to automatically engage and disengage based on the position of the top and the state of the lock actuator. The biasing member provides automatic return to the latched position, reducing the need for manual intervention and simplifying operation while maintaining reliability.

Inventive Principle:
Principle #25Self-service

4Ease of operation

If visual and tactile cues are provided to indicate locked state, then ease of operation is improved, but the device complexity increases

Engineering Contradiction:
Improvelocked state indicationVSAvoidfeedback mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system uses visual indicators such as color changes or position indicators on the lock actuator or latch to show the locked state. These indicators provide immediate visual feedback to passengers about the storage container status without requiring complex electronic displays or additional mechanical components.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The locked state indication is provided through the natural position and feel of the lock actuator and latch mechanism itself. The tactile feedback from the mechanism's position and the visual cues from component alignment provide intuitive indication of the locked state without requiring separate feedback systems.

Inventive Principle:
Principle #25Self-service

AI summary

A storage container (100) has a base (102) defining at least one storage compartment (202, 204, 206, 208, 210, 212), a top (104) movable between closed and opened positions, latching and locking assemblies. The latching assembly (500) has a latching actuator (110) movable between first and second positions. The latching assembly (500) locks the top (104) to the base (102) when the top (104) is in the closed position and the latching actuator (110) is in the first position and releases the top (104) from the base (102) when the latching actuator (110) is in the second position. The locking assembly has a lock actuator (801) having actuated and released positions. The top (104) is movable when the lock actuator (801) is in the actuated position. The locking assembly locking the top (104) in the open, closed, or an intermediate position when the lock actuator (801) is in the released position. The latching actuator (110) and the lock actuator (801) are operatively connected to the top (104) and move with the top (104) between the closed and the opened position.
