Solution Overview
Problem
Existing stackable container devices face challenges in mechanical resistance during vertical stacking, particularly with dense products like fruits and vegetables, and have complex assembly processes that are difficult to automate.
Innovation Solution
A stackable container device with a tray and reinforcement devices that include a main face extending along the transverse wall and a folded face at right angles, featuring additional attachment members such as upper tabs, lateral tongues, and folded sections to securely attach the sidewalk sections, enhancing mechanical resistance and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If sidewalks are integrated into the board with complex transverse end plates, then mechanical resistance to stacking is improved, but device complexity increases and assembly automation becomes difficult
Solution Approach 1:
The reinforcement device is divided into separate modular components: a sidewalk element and transverse end plates that are not integrated into the board but are distinct parts. This segmentation simplifies the overall structure while maintaining stacking strength, as each component can be independently manufactured and assembled.
Solution Approach 2:
The transverse end plates are designed with pre-formed geometric features (such as inclined surfaces and positioning elements) that enable automatic alignment and insertion during assembly. This preliminary design of geometric constraints allows assembly automation without requiring complex control of dimensional dispersions.
2Strength
If sidewalks are integrated into the board, then mechanical resistance to stacking is improved, but assembly operation becomes tricky to automate due to obstacles
Solution Approach 1:
By separating the sidewalk element from the transverse end plates, the assembly process is simplified. The transverse end plates can be independently inserted without the sidewalks constituting obstacles, as they are attached to different structural elements (longitudinal walls rather than integrated into the board).
Solution Approach 2:
The transverse end plates act as intermediary elements that connect the sidewalk to the longitudinal walls. This intermediary structure provides a clear path for automated insertion, with geometric features that guide the assembly process and eliminate the need for tricky manual manipulation.
3Strength
If reinforcement devices are added to enhance mechanical resistance, then strength during vertical stacking is improved, but device complexity increases
Solution Approach 1:
The transverse end plates serve multiple functions: they reinforce the tray structure for vertical stacking, provide attachment points for sidewalks, and enable assembly automation through their geometric design. This multi-functionality reduces the need for additional specialized components, thereby limiting the increase in device complexity.
Solution Approach 2:
The reinforcement is achieved by changing the geometric parameters of the transverse end plates (such as thickness, inclination angles, and positioning) rather than adding complex structural features. This allows strength enhancement while maintaining a relatively simple device architecture.

AI summary
A stackable container device comprising a platform having a horizontal base (12D), two longitudinal walls (12L), and two solid transverse walls (12T). This device includes two horizontally oriented transverse walkways on the inner side of the platform, which, together with a horizontal upper edge (28) of the platform walls, form a stacking support at their corners where the longitudinal and transverse walls meet. Corresponding to each solid transverse wall (12T), the container device includes a reinforcement device (13) embedded in the platform, having, on the one hand, a main panel (33) extending along the entire length of said transverse wall, from the base (12D) to the upper edge (28), and on the other hand, connected at the top of the main panel (33), a folded panel (30) forming the walkway.The reinforcement device (13) includes additional attachment elements (37, 39) for the sidewalk section (30) by fixing it horizontally.
