Multi-Door Container Locking System with Independent Latch Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial storage containers with multiple doors lack efficient and independent locking mechanisms, making it difficult to secure and access specific compartments without compromising the security of others.
Innovation Solution
A container design featuring multiple pivotally attached doors with latch units and a locking system that allows each door to be independently latched or unlatched using a locking member and biasing spring, enabling secure access to the container while preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a locking mechanism is positioned on a panel between multiple doors to simultaneously open all doors, then the locking system can secure all doors with one movement, but it becomes impossible to access individual compartments independently without compromising security of other compartments
Solution Approach 1:
The locking system is segmented into multiple independent locking members (first locking member, second locking member, third locking member), each associated with a specific door. This allows each door to be locked or unlocked independently while maintaining the ability to secure all doors simultaneously when needed.
Solution Approach 2:
The locking system incorporates a shared control mechanism that can operate all locking members through a single action, while also allowing individual control of each locking member. This multi-functionality enables both simultaneous locking of all doors and independent access to specific compartments.
2Adaptability or versatility
If each door has its own independent locking mechanism, then individual compartments can be accessed independently, but the device complexity and number of components increases
Solution Approach 1:
Multiple locking members are merged into a single integrated locking system assembly that includes a shared control mechanism, actuator, and housing structure. This reduces the overall complexity compared to having completely separate locking mechanisms for each door, while still maintaining independent control capability.
Solution Approach 2:
The locking system incorporates movable locking members that can be selectively positioned to engage or disengage from their respective doors. The dynamic nature of the system allows it to adapt between locked and unlocked states for individual doors or all doors simultaneously, reducing the need for complex fixed structural arrangements.
3Reliability
If a locking mechanism secures all doors simultaneously, then security is maintained across all compartments, but it becomes difficult to access specific compartments without opening all doors
Solution Approach 1:
The locking system is divided into separate controllable units (locking members) for each door, allowing selective engagement. This segmentation enables the operator to maintain security by locking all doors when needed, while also allowing easy access to specific compartments by unlocking only the required door.
Solution Approach 2:
Each locking member is designed to be independently controllable through the shared control mechanism, allowing the system to serve itself by maintaining security for locked compartments while providing automatic access to unlocked compartments without requiring manual intervention for each individual door.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides secure, independent control over each door, allowing for easy access to one compartment while maintaining others locked, enhancing security and usability.
Implementation Method 1
A locking system is coupled to the first and second latch units for moving the first and second latch units between the latched and the unlatched positions. The locking system includes a locking member movable between a first position, in which the locking member moves the first latch unit of the first door from the latched to the unlatched position, and a second position, in which the locking member moves the second latch unit of the second door from the latched to the unlatched position.

AI summary
A container includes a receptacle having walls, a floor, and an open side. The container includes first and second doors. At least one first latch unit is operatively associated with the first door and is movable between a latched position and an unlatched position. At least one second latch unit is operatively associated with the second door and is movable between a latched position and an unlatched position. A locking system for moving the first and second latch units between the latched and the unlatched positions includes a locking member movable between a first position in which the locking member moves the first latch unit of the first door from the latched to the unlatched position and a second position in which the locking member moves the second latch unit of the second door from the latched to the unlatched position.
