Solution Overview
Problem
Individuals face the challenge of managing fluctuating temperatures while outdoors, where they may need to switch between wearing an upper garment and carrying a backpack, and vice versa, without the convenience of easily converting between the two.
Innovation Solution
A convertible backpack garment assembly that can be transformed from an upper garment (like a vest) into a backpack, or vice versa, featuring zippers, straps, and pockets for easy conversion and improved weight distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a person carries a backpack all day, then they can transport gear and provisions, but it strains their back and is unnecessary when weather turns warmer
Solution Approach 1:
The garment is designed to serve dual functions: as a wearable upper garment when unfolded and as a backpack when folded and zipped. The same fabric structure, zippers, and straps serve both purposes, eliminating the need to carry separate items for different weather conditions.
Solution Approach 2:
The garment incorporates multiple zippers (front zipper, side zippers, pocket zippers) that can be independently opened or closed during conversion. This segmentation allows the garment to be partially folded and zipped into a compact backpack configuration without requiring complete disassembly.
2Adaptability or versatility
If a person wears an upper garment all day, then they are protected from cold weather, but it becomes unnecessary and bulky when temperature increases
Solution Approach 1:
The same fabric and structural elements serve as both the outer garment and the backpack body. The zippers and straps are identical in both modes, reducing overall design complexity while maintaining dual functionality.
Solution Approach 2:
When converted to a backpack, the garment folds into a compact nested structure where the front panel folds over the back panel, and pockets are folded inward. This nesting creates a space-efficient backpack configuration from the same flat garment layout.
3Ease of operation
If a person removes their upper garment when weather warms up, then they are more comfortable, but they risk forgetting or losing it
Solution Approach 1:
The garment converts itself into a backpack without requiring the user to manually pack items. The user simply unzips the front zipper and folds the garment along predetermined lines, and the structure automatically forms a functional backpack ready to carry.
Solution Approach 2:
The garment eliminates the need to separate the jacket from the backpack function. When removed as a garment, it can be immediately converted to a backpack and carried, ensuring the user never loses the outer layer.
4Adaptability or versatility
If a person carries a backpack when weather cools down, then they can wear it as a jacket, but it is inconvenient to convert from backpack to garment mode
Solution Approach 1:
The garment is pre-designed with built-in conversion features including positioned zippers, marked fold lines, and integrated straps that are ready for immediate conversion. The front zipper is positioned to open into the backpack opening, and side zippers are pre-placed for quick access during conversion.
Solution Approach 2:
The conversion process is divided into simple sequential steps: open front zipper, fold front panel over back panel, zip side zippers, and adjust straps. This segmentation into discrete actions makes the conversion quick and intuitive.
