Angled Door Cargo Locker with Spring-Loaded Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo transportation lockers suffer from hinge damage and structural deformation under heavy loads or movement, and their design often restricts stacking and handling efficiency.
Innovation Solution
The cargo transportation locker features angled door members and corner posts, a slideable locking mechanism, and spring-loaded sliding members to enhance structural integrity, prevent hinge damage, and facilitate secure stacking and handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional hinged doors are used in lockers, then the doors can swing open and closed for cargo access, but the hinges are often damaged when moving cargo around the lockers or when moving the lockers themselves
Solution Approach 1:
The door assembly is segmented into multiple components: angled door members, horizontal support members, and vertical support members that work together to distribute loads and prevent hinge damage while maintaining door functionality
Solution Approach 2:
The door structure uses composite construction combining angled door members with horizontal and vertical support members to create a rigid framework that protects hinges from damage while allowing door operation
2Device complexity
If traditional locker structures are used, then they can be simple in design, but structural shape tends to deform under large weight loads or during movement or stacking
Solution Approach 1:
The locker structure is divided into multiple corner posts connected by horizontal and vertical support members, creating a modular framework that maintains structural integrity under heavy loads while remaining relatively simple in design
Solution Approach 2:
The support members are positioned asymmetrically to optimize load distribution across the structure, preventing deformation under heavy weights while maintaining overall structural simplicity
3Weight of moving object
If lockers are designed for heavy load capacity, then they can handle up to 5000 lbs, but the locking mechanism becomes vulnerable to damage during transport and use
Solution Approach 1:
The locking mechanism is nested within the protected interior space of the locker, surrounded by corner posts and support members that physically shield it from external damage during transport and use
Solution Approach 2:
The locking mechanism is positioned within a pre-designed protective framework of corner posts and support members that anticipates and prevents damage before it occurs during handling and transport
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 allows for the handling of heavy loads up to 5000 lbs, secure stacking, and improved rigidity, while protecting the locking mechanism from damage during transport and use.
