Solution Overview

Problem

Current cargo systems face challenges in efficiently transporting both liquid and solid goods simultaneously, as they either require separate compartments or compromise on space and efficiency due to the need for distinct configurations for each type of cargo.

Innovation Solution

A cargo system with bellows-sided compartments that adjust height based on fill level, utilizing rubber and graphene for flexibility and strength, and a rectangular cargo-receiving surface that adapts to the compartment's fullness, allowing for simultaneous transport of both liquid and solid goods by maximizing space when empty and accommodating uneven cargo distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate compartments are used for liquid and solid goods, then cargo types can be differentiated, but space utilization and transport efficiency deteriorate

Engineering Contradiction:
Improvecargo type differentiationVSAvoidtransport efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The partition wall is designed as a movable bellows structure that can dynamically adjust its height and position based on the volume of liquid cargo. This dynamic adjustment allows the partition to adapt to different cargo configurations, enabling both liquid and solid goods to be transported efficiently in the same cargo space without compromising separation or space utilization.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The cargo space is segmented into multiple compartments by movable partition walls that can be positioned independently. This segmentation allows different types of cargo to be separated when needed, while the movable nature of the partitions ensures that space is optimized based on actual cargo volumes, preventing the efficiency loss associated with fixed separate compartments.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If fixed height compartments are used, then structural simplicity is maintained, but space utilization deteriorates when cargo volume varies

Engineering Contradiction:
Improvestructural simplicityVSAvoidcargo space utilization
Core Design Contradiction:
Device complexityVSVolume of moving object

Solution Approach 1:

The bellows-shaped partition walls replace fixed-height structures with dynamic, adjustable surfaces. These bellows structures expand and contract based on liquid cargo volume, automatically optimizing cargo space utilization without requiring complex mechanical adjustment mechanisms, thus maintaining relative structural simplicity while dramatically improving volume efficiency.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The partition walls change their geometric parameters (height, surface area, volume) in response to cargo volume changes. The bellows structure allows the partition to smoothly adjust its dimensions as liquid is added or removed, ensuring that cargo space is always optimized to match the actual cargo present, whether full or partially filled.

Inventive Principle:
Principle #35Parameter changes

3Strength

If bellows sides with rubber and graphene are used, then flexibility and strength are improved, but manufacturing complexity increases

Engineering Contradiction:
Improvepartition wall strengthVSAvoidmanufacturing complexity
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The partition walls utilize a composite material system combining rubber for flexibility with graphene for exceptional strength. This composite approach allows the bellows structure to achieve the necessary mechanical properties for cargo containment while maintaining the flexibility required for volume adjustment. The material selection balances performance requirements with manufacturing feasibility, as both rubber and graphene are established materials with known processing methods.

Inventive Principle:
Principle #40Composite materials
