Aluminium Box Frame Profile for Secure Transport Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aluminium boxes tend to slide on surfaces during transportation due to lack of efficient and reliable securing mechanisms, despite being stackable and durable.
Innovation Solution
A metal profile with a cross-section featuring a cavity enclosed by a first flange, a bottom part, and a recess enclosed by a second flange side, which includes a protrusion to create a one-side or two-side open recess, allowing for secure attachment to a surface using brackets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional aluminium boxes are used with stacking corners, then the boxes can be stacked vertically, but the boxes tend to slide on surfaces during transportation
Solution Approach 1:
The aluminium box is divided into separate functional components: a base box for stacking and a separate frame structure with protrusions and recesses for securing. This segmentation allows the stacking function to remain intact while adding a dedicated securing mechanism that prevents sliding during transportation.
Solution Approach 2:
A coupling system acts as an intermediary between the aluminium box and the transport surface. The frame with its protrusions and recesses creates a mechanical interface that mediates the connection, transforming the unstable sliding contact into a stable secured position through bracket engagement.
2Reliability
If straps are used to secure aluminium boxes to surfaces, then the boxes can be restrained from moving, but the securing method is not efficient or reliable
Solution Approach 1:
The frame structure is designed to be self-securing through its geometric features. The protrusions fit into recesses on the transport surface, creating a self-aligning and self-securing mechanism that does not require external straps or complex fastening systems, thereby improving reliability while reducing overall system complexity.
Solution Approach 2:
The frame is pre-configured with specific protrusion and recess patterns during manufacturing. This preliminary action ensures that when the box is placed on the transport surface, the securing geometry is already in place, eliminating the need for complex real-time adjustment mechanisms and improving both reliability and ease of use.
3Ease of operation
If aluminium boxes are designed to be lightweight and simple, then they are easy to transport and erect, but they lack an integrated securing mechanism
Solution Approach 1:
The frame structure serves multiple functions: it provides the structural boundary for the aluminium box, enables stacking through its geometric design, and secures the box to transport surfaces through protrusions and recesses. This multi-functionality maintains the lightweight and simple design while adding securing adaptability without requiring separate dedicated components.
Solution Approach 2:
The securing mechanism is nested within the overall frame structure of the aluminium box. The protrusions and recesses are integrated into the frame's geometry rather than being separate attachments, allowing the securing function to be embedded within the existing lightweight design, thereby maintaining transport ease while gaining securing adaptability.
