Tritan Travel Kit with Segmented Containers and Locking Seals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current travel tubes for liquid personal care products are difficult to fill, clean, and not designed for long-term storage, often leading to waste and leakage, and are not suitable for compliance with TSA 311 rules, which require liquids to be in containers of 3.4 ounces or less.
Innovation Solution
A travel kit with a carrying case and containers made from durable, dishwasher-safe Tritan material, featuring a locking mechanism, hexagonal raised edges for secure placement, and a design that accommodates freezing liquids without breaking the seal, ensuring watertight storage and compliance with TSA regulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If inexpensive travel tubes are used, then cost is reduced, but ease of operation deteriorates (difficult to fill and clean)
Solution Approach 1:
The travel kit is divided into multiple separate containers (3-5 containers of different sizes) that can be individually filled and cleaned. Each container has a wide mouth opening that facilitates easy filling and cleaning, while the segmented structure allows travelers to optimize space usage by selecting appropriate container sizes for different liquid products.
2Adaptability or versatility
If standard travel tubes are used, then availability is improved, but reliability deteriorates (not watertight sealed, may leak)
Solution Approach 1:
The sealing function is extracted as a separate component - a silicone gasket is incorporated into the lid assembly, distinct from the container body. This dedicated sealing element provides reliable watertight closure while allowing the container body to maintain a simple, available design. The gasket ensures leak-proof sealing even when containers are stacked or subjected to pressure changes during air travel.
3Quantity of substance
If small travel containers are used, then compliance with TSA rules is improved, but loss of substance worsens (unused lotion must be discarded)
Solution Approach 1:
The kit includes multiple containers of varying sizes (1oz, 2oz, 3oz options) that allow travelers to segment their liquid products according to trip duration and usage needs. This segmentation enables optimal utilization of each container, reducing waste by matching container size to actual consumption requirements while maintaining TSA compliance with the 3.4oz limit per container.
4Weight of moving object
If current travel tubes are used, then portability is improved, but durability deteriorates (not meant for long-term storage, not dishwasher safe)
Solution Approach 1:
The containers are constructed from Tritan copolyester, a durable composite material that combines the lightness and portability needed for travel with the strength and heat resistance required for long-term storage and dishwasher cleaning. This material selection resolves the contradiction by providing a composite structure that simultaneously achieves portability and durability.
