Waterproof Pouch Buoyancy Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cell phone waterproof bags have insufficient buoyancy, making it difficult for medium-sized or large phones to float, and often require complex inflation or regulation processes, leading to a poor user experience.
Innovation Solution
A cell phone waterproof bag design featuring a bag body divided into an upper wide part and a lower narrow part with an airtight zipper and a buoyancy-enhancing component, such as a transparent membrane body or airbag shell, providing increased buoyancy and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof bag uses a standard airbag shell structure, then the bag can provide buoyancy, but the buoyancy is insufficient for medium-sized or large cell phones and the bag becomes too complex to use
Solution Approach 1:
The airbag shell is divided into multiple independent air chambers (first air chamber, second air chamber, third air chamber) with different buoyancy values. This segmentation allows the total buoyancy to be distributed across multiple smaller units, providing sufficient overall buoyancy for larger phones while keeping each individual chamber simple in structure and easy to manufacture.
2Reliability
If the airbag shell is positioned in the center of the bag body, then the structure is simple, but the buoyancy is insufficient for medium-sized or large cell phones
Solution Approach 1:
Instead of using a single centralized airbag, the design employs multiple distributed air chambers positioned at different locations within the bag body. This segmentation provides sufficient total buoyancy for larger phones while maintaining manufacturing simplicity through modular construction of identical or similar chamber units.
Solution Approach 2:
The air chambers are arranged in a three-dimensional distribution pattern within the bag body rather than concentrating buoyancy in a single central location. This spatial distribution optimizes buoyancy effectiveness and allows the bag to support larger phones while maintaining a manageable structural design.
3Ease of manufacture
If the bag mouth uses plastic card heads or plastic clips to seal, then the sealing is simple, but water can easily enter the bag mouth
Solution Approach 1:
The traditional mechanical sealing system (plastic card heads or clips) is replaced with an airtight zipper sealing mechanism. This new system provides superior waterproof performance by creating an airtight seal along the entire bag mouth perimeter, while still maintaining relative simplicity in structure and ease of operation.
4Adaptability or versatility
If airbag shells require inflation and deflation processes or complex valves to form airbags, then the buoyancy can be adjusted, but the user experience becomes very inconvenient
Solution Approach 1:
The airbag system is segmented into multiple pre-formed air chambers with fixed buoyancy values. Users can achieve buoyancy adjustment by selecting different combinations of chambers or by using the detachable design to add or remove chambers, eliminating the need for complex inflation/deflation processes while maintaining adaptability for different phone sizes.
Solution Approach 2:
The airbag structure incorporates a detachable and reconfigurable design, allowing users to dynamically adjust the buoyancy configuration by assembling or disassembling air chamber units. This dynamic adaptability provides versatility for different phone sizes without requiring complex active control mechanisms.
