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

VSEngineering 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

Engineering Contradiction:
Improveleakage preventionVSAvoidpackaging structure
Core Design Contradiction:
ReliabilityVSDevice complexity

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.

Inventive Principle:
Principle #7Nested doll (Nesting)

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improvepackaging productionVSAvoidleakage prevention
Core Design Contradiction:
Ease of manufactureVSReliability

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.

Inventive Principle:
Principle #7Nested doll (Nesting)

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the packaging provides full coverage and protection, then the reliability is improved, but the visibility of the object deteriorates

Engineering Contradiction:
ImproveprotectionVSAvoidobject visibility
Core Design Contradiction:
ReliabilityVSIllumination intensity

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.

Inventive Principle:
Principle #3Local quality

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

Engineering Contradiction:
ImprovehandlingVSAvoidcontact risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

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.

Inventive Principle:
Principle #24Intermediary (Mediator)
