Corrosive Liquid Package with Wedge Stabilization and Sealed Bag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging solutions for corrosive liquid-containing objects, such as automobile batteries, are not compatible with standard transportation methods due to safety regulations, leading to increased costs and risks of leakage or damage during handling and shipping.
Innovation Solution
A packaging system comprising a cardboard box with a base, transverse faces, and main faces that split to form flaps, secured with a binding strip, and featuring wedges to prevent slipping and falling, along with a sealed plastic bag to contain the corrosive liquid, ensuring visibility and secure handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the packaging is made tight and sealed to prevent leakage, then the reliability is improved, but the complexity of the packaging structure increases
Solution Approach 1:
The battery is nested within a waterproof bag, which is then placed inside a cardboard box. This nested structure provides multiple layers of protection against leakage while maintaining a relatively simple overall packaging design. The waterproof bag acts as the inner layer and the cardboard box as the outer layer, creating a reliable containment system without excessive complexity.
Solution Approach 2:
The packaging is segmented into distinct functional components: the waterproof bag for liquid containment, the cardboard box for structural support and protection, and the binding strip for securing. This segmentation allows each component to perform its specific function efficiently, achieving reliable leakage prevention through the waterproof bag while the cardboard box provides simple structural protection.
2Ease of manufacture
If the packaging is made simple and easy to manufacture, then the ease of manufacture is improved, but the reliability of leakage prevention deteriorates
Solution Approach 1:
The nested structure of placing the battery in a waterproof bag and then in a cardboard box allows for simple manufacturing of each individual component using standard materials and techniques, while the combination provides reliable leakage prevention. The waterproof bag can be manufactured using simple plastic materials, and the cardboard box using conventional box-making processes.
Solution Approach 2:
The waterproof bag serves as an intermediary element between the battery and the external environment. This intermediary layer provides reliable leakage prevention while allowing the packaging to remain simple in structure. The bag acts as a barrier that isolates the corrosive electrolyte from potential damage sources.
3Reliability
If the packaging provides full coverage and protection, then the reliability is improved, but the visibility of the object deteriorates
Solution Approach 1:
The cardboard box provides full coverage protection for the battery, while the transparent or translucent nature of the cardboard material allows visibility of the battery through the box walls. This local quality of the packaging material simultaneously achieves both protection and visibility requirements without compromising either.
4Ease of operation
If the packaging is designed for easy handling with handles, then the ease of operation is improved, but the risk of contact with the object increases
Solution Approach 1:
The cardboard box acts as an intermediary barrier between the handler's hands and the battery. The handles are formed in the cardboard box itself, allowing easy handling while the box material prevents direct contact between the hands and the corrosive battery, eliminating the contact risk.

AI summary
The present invention relates to a package consisting of a box (3) made from a blank by cutting and grooving comprising a base, two transverse faces (5, 5'), two principal faces (4), a transported object (1) of prismatoid shape, the height of which is less than that of the transverse faces (5, 5'), and comprising in the upper part at least one orifice fitted with a plug for filling with a corrosive liquid, being placed on the base, with wedges (6) interposed between the transverse faces (5') and the object (1), and the principal faces (4) being split on their end opposite the base so as to provide flaps (7) covering a part of the upper part of the transported object (1), said object (1) being secured to the box by a tie (9) resting on the flaps (7).
