Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor storage bags with transparent windows for mobile phone access do not adequately protect the phone from damage during bumps and water exposure, especially when used for cycling or water sports.
Innovation Solution
A waterproof outdoor storage bag design featuring a bag body and cover with a zipper, a mobile phone screen window, elastic fixing straps, a protective frame with drainage and diversion grooves, and a reversible soft edge to ensure secure phone placement and water resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a transparent window is arranged on the storage bag to view the mobile phone, then ease of operation is improved, but protection against damage is worsened
Solution Approach 1:
The storage bag is segmented into distinct functional zones: a waterproof bag body for storage, a separate bag cover with transparent window for phone access, and a protective frame structure. This segmentation allows the phone compartment to provide viewing access while the bag body maintains protection capabilities.
Solution Approach 2:
The mobile phone compartment with transparent window is nested within the bag cover, which itself is nested within or integrated with the bag body. The protective frame is nested around the phone compartment, creating layered protection where the phone can be viewed through the window while remaining protected by multiple structural layers.
2Ease of operation
If the mobile phone is fixed in the transparent window, then ease of operation is improved, but the storage bag cannot protect the mobile phone from damage
Solution Approach 1:
A protective frame acts as an intermediary structure between the mobile phone and the external environment. This frame provides mechanical strength and protection while allowing the transparent window to function for phone viewing and operation, thus mediating between the need for accessibility and the need for protection.
Solution Approach 2:
The bag cover incorporates multiple materials with different properties: transparent material for the window, protective frame material for structural strength, and elastic fixing strap material for securement. This composite structure provides both phone accessibility through the transparent window and damage protection through the robust frame and securing mechanisms.
3Reliability
If a protective frame is added around the mobile phone window, then protection against damage is improved, but device complexity is worsened
Solution Approach 1:
The protective frame serves multiple functions simultaneously: it provides structural protection for the mobile phone, supports the transparent window, incorporates drainage groove channels for water management, and integrates with the elastic fixing straps for phone securation. This multi-functionality reduces the need for separate components, thereby limiting the increase in complexity despite enhanced protection.
Solution Approach 2:
The protective frame merges several protective and functional elements into a single integrated structure: protection against damage, water drainage capabilities through groove channels, and support for the transparent window. By combining these functions into one component rather than separate parts, the overall structural complexity is minimized while maintaining comprehensive protection.
4Object-affected harmful factors
If drainage groove channels are arranged on the protective frame, then resistance to water is improved, but device complexity is worsened
Solution Approach 1:
The protective frame incorporates drainage groove channels that function as integrated water management features within the frame structure itself, rather than requiring separate waterproofing components. The groove channels provide water resistance by directing water flow away from the mobile phone compartment, achieving protection through a relatively simple structural modification to the frame.
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 solution provides secure phone access, protection from bumps and water, and effective drainage to prevent water accumulation, enhancing usability and durability during cycling and water sports.
Implementation Method 1
An elastic fixing strap for a mobile phone is respectively fused to two sides, which correspond to the mobile phone screen window, at a lower end of the bag cover, and a hook and a loop which are adhered to each other are arranged at ends of the two elastic fixing straps for the mobile phone
Implementation Method 2
drainage groove channels are arranged at a rear end of the protective frame
Implementation Method 3
diversion groove channels that extend to both sides of the protective frame are arranged on an upper edge of a front side of the protective frame

AI summary
A waterproof outdoor storage bag comprises a bag body and a bag cover covering the upper end of the bag body. A zipper is arranged between the upper edge of the bag body and the lower edge of the bag cover, and the bag body and the bag cover are opened and closed by the zipper. A positioning strap is arranged at the bottom of the bag body. The bag cover is provided with a mobile phone screen window. A mobile phone stop frame is arranged on the edge of the mobile phone screen window. An elastic fixing strap for a mobile phone is respectively fused to two sides, which correspond to the mobile phone screen window, at the lower end of the bag cover, and a hook and a loop adhered to each other are arranged at the ends of the two elastic fixing straps for the mobile phone.
