Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waterproof bags for water-play areas are either water-resistant but not suitable for underwater use or designed for mobile phones alone, lacking convenience and safety for other personal belongings.
Innovation Solution
A bag set comprising a main bag unit with a strap set and a separate mobile phone bag unit, both with waterproof designs, allowing the mobile phone to be quickly detached and reattached, and securely attached to the main bag for underwater use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof backpack is used to store personal belongings, then the belongings are protected from water, but the backpack must be detached from the user's body before taking out belongings, reducing convenience
Solution Approach 1:
The invention divides the waterproof storage system into two independent parts: a waterproof backpack for general belongings and a separate waterproof mobile phone bag for electronic devices. This segmentation allows the mobile phone bag to be quickly detached and accessed independently, improving convenience without compromising the waterproof protection of the main backpack.
2Reliability
If a waterproof mobile phone bag is used to store mobile phones, then the mobile phone is protected from water, but the bag volume is limited and cannot accommodate other personal belongings
Solution Approach 1:
The invention creates a modular waterproof system where the mobile phone bag is a separate, smaller unit optimized for electronic devices, while the main backpack provides larger capacity for other belongings. Together they form a complete waterproof storage solution that exceeds the capacity of either bag alone.
Solution Approach 2:
The invention combines two waterproof bags of different sizes and functions into a coordinated system. The mobile phone bag can be attached to or carried with the main backpack, creating a unified waterproof storage solution that provides both electronic device protection and general belongings storage.
3Stability of the object's composition
If general waterproof backpacks are stitched along folds or edges, then the backpack structure is maintained, but water can penetrate through folds or edges when placed underwater
Solution Approach 1:
The invention uses heat fusion technology to seal the waterproof fabric layers together, creating a continuous waterproof barrier without traditional stitching. This fusion method eliminates needle holes and seam weaknesses that would allow water penetration, while maintaining the flexibility and structural integrity of the waterproof bags.

AI summary
A bag set comprises a first bag unit combined with a second bag unit. The first bag unit includes a main bag body and a strap set. The main bag body has two first fasteners disposed on an outer surface. The strap set includes a first strap component having two ends connected with the main bag body, and a second strap component having a loop structure and one end connected with the main bag body. The second bag unit has two second fasteners to be attached to or disassembled from the two first fasteners selectively. When in use, the first strap component is hung diagonally on a shoulder of a user; and the second strap component is extended forward from the waist of the user to make the loop structure positioned in front side of the user, to pass the first strap component through the loop structure.
