Stackable Container Hinged Walls Recess Covering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stackable containers face issues with loose individual parts, increased height when folded, and laborious handling due to vertically displaceable side wall elements, which can be lost or damaged, and require awkward manual repacking for transport and presentation.
Innovation Solution
A container design featuring a horizontally displaceable wall rail with obliquely positioned wall braces that cover and uncover a recess in the wall, allowing for secure transport and easy presentation, with adjustable latches to prevent accidental opening, and the ability to be manufactured at low cost with minimal height in the folded state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vertically displaceable roller blind is provided to close the opening in the side wall, then the opening can be closed for transport, but the base height increases and the container height increases when walls are folded in
Solution Approach 1:
The roller blind mechanism is extracted from the base structure and relocated to the wall rail system. The wall rail with roller blind is now a separate component that attaches to the wall frame, allowing the base to remain low while still providing closure functionality for the side wall opening during transport.
2Stability of the object's composition
If a vertically displaceable side wall element is integrated into the container base, then the side wall can be secured, but handling becomes laborious and awkward
Solution Approach 1:
The side wall element is designed with dynamic positioning capability through the wall rail system. The roller blind can be easily displaced vertically along the wall rail to adjust the opening size or close it completely, providing both stability when closed and ease of operation when adjusted, eliminating the laborious handling associated with fixed base-integrated elements.
3Adaptability or versatility
If the lid is a loose individual part of the container, then it can be removed for access, but the risk of losing the lid increases
Solution Approach 1:
The lid is merged with the wall rail assembly rather than being a completely separate loose part. The wall rail with roller blind and lid forms an integrated front wall assembly that can be easily attached and detached, providing versatile access while reducing the risk of losing the lid through misplacement, as it remains connected to the wall structure.
4Adaptability or versatility
If side wall inserts are provided as loose individual parts, then the container can be adapted for different uses, but the parts can easily be lost and damaged
Solution Approach 1:
The wall rail assembly with roller blind serves multiple functions: it provides closure for the side wall opening, acts as a structural frame element, and can accommodate different wall configurations. This multi-functional design eliminates the need for separate loose inserts, maintaining adaptability while improving reliability by integrating all necessary components into the main wall structure.
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 a secure, easy-to-handle container for both transport and presentation that minimizes the risk of parts being lost or damaged, maintains a low height when folded, and allows for convenient item access without the need for manual repacking, suitable for applications like food logistics.
Implementation Method 1
a wall rail (3) running horizontally parallel to the base (10) which is vertically displaceable in sliding guides (23) running along the lateral edges (21) of the recess (2)
Implementation Method 2
at least two wall braces (4) which are hinged at their ends (41) in each case in a hinged manner to the wall rail (3) and at the lower edge (20) of the recess (2) to the wall (11') having the recess (2)

AI summary
A stackable container including a rectangular base and four side walls hinged to the base. The side walls pivot between an erected useful position and an empty position folded in towards the base. At least one of the walls has a selectively covered or uncovered recess spaced from two lateral edges and a lower edge of this wall. A wall rail arranged parallel to the base is vertically displaceably guided in sliding guides between an upper covering and a lower uncovering position. Between the wall rail and the lower edge of the recess are at least two wall braces that, in the covering position, run obliquely and are spaced apart from one another in a longitudinal direction of the wall and are each connected at their ends in a hinged manner to the wall rail and, at the lower edge of the recess, to the wall having the recess.
