Integrated container-suspension system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing banana storage systems face issues such as bruising, accelerated ripening due to ethylene gas emission from other fruits, and safety hazards from hook-based designs that pierce the banana stem, limiting the number of hands that can be suspended and requiring excessive force for handling.
Innovation Solution
A dynamic non-piercing container-suspension system featuring a receptacle with a vertical extension and base legs that allow for stable suspension of bananas without direct contact, using suspension strands that can suspend multiple bananas without piercing, and an oxidizer to neutralize ethylene gas, ensuring gentle handling and minimizing exposure to ethylene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid hook-based suspension system is used, then bananas can be suspended without contact with other fruit, but the system requires excessive force for handling and may pierce the banana stem causing safety hazards
Solution Approach 1:
The patent replaces rigid hooks with flexible suspension strands that can adapt to the banana hand shape without requiring excessive force. The flexible material allows gentle engagement with the banana stem, eliminating piercing while maintaining suspension stability through elastic deformation and conformal contact.
2Area of stationary object
If bananas are stored in a bowl with other fruit, then the container footprint is minimized, but bananas bruise from contact with other fruit and accelerate ripening due to ethylene gas
Solution Approach 1:
The patent transitions from horizontal storage (bananas lying in a bowl) to vertical suspension (bananas hanging above the bowl). This dimensional change allows bananas to be stored above other fruit in the bowl, eliminating contact-related bruising and reducing ethylene exposure while maintaining a compact countertop footprint through vertical space utilization.
3Productivity
If ethylene-emitting fruit like apples and pears are stored near bananas, then container space is efficiently utilized, but bananas ripen and spoil faster due to ethylene gas accumulation
Solution Approach 1:
The patent extracts bananas from the ethylene-rich environment created by other fruit in the bowl. By suspending bananas vertically above the bowl rather than storing them alongside ethylene-emitting fruit, the system separates bananas from the harmful ethylene atmosphere, preserving freshness while maintaining efficient container utilization through multi-level storage.
4Reliability
If a sharp-tipped hook is used to pierce the banana stem for suspension, then secure suspension is achieved, but safety hazards and bacterial contamination risks increase
Solution Approach 1:
The patent employs disposable or easily cleanable flexible suspension strands instead of permanent sharp hooks. These strands can be discarded or sanitized after use, eliminating the accumulation of bacterial residue that occurs with reusable piercing hooks while maintaining secure suspension through flexible engagement rather than piercing.
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 system effectively prevents bruising and premature ripening of bananas by distributing weight evenly and neutralizing ethylene gas, while providing a safe and flexible handling mechanism that supports multiple bananas without the need for piercing or excessive force.

AI summary
Disclosed is a fresh fruit storage and display system that enables the storage of bananas and other fruit in a manner that does not result in damage to the bananas (e.g., bruising, aging, etc.) stemming from contact with other fruit or exposure to ethylene gas emitted by the other fruit, and featuring a dynamic suspension component for enhanced suspended storage (without piercing) of a hand of bananas and/or a single banana.
