Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling backpacks are cumbersome, occupy valuable space, and are inconvenient to maintain due to complex designs and lack of structures for enhanced user comfort.
Innovation Solution
A backpack with a cooling unit that includes a TEC cooling plate and a fan, integrated with a ring-shaped flexible protrusion and flexible support for better back contact, and a detachable cooling unit for easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the exhaust fan, power source, and thermoelectric cooling plate are installed inside the backpack cavity, then cooling functionality is achieved, but the storage capacity is reduced and maintenance becomes difficult
Solution Approach 1:
The cooling system is divided into separate modular components: the exhaust fan is mounted on the back panel, the power source is integrated into the shoulder straps, and the thermoelectric cooling plate is positioned in the cavity. This segmentation allows each component to occupy different spatial zones, maximizing storage capacity while maintaining cooling functionality.
Solution Approach 2:
A detachable connection structure serves as an intermediary between the cooling components and the backpack body. This intermediary mechanism enables easy installation and removal of the cooling plate, facilitating maintenance while preserving both cooling performance and storage space.
2Stability of the object's composition
If the exhaust fan, power source, and cooling plate are fixed to the bottom of the cavity, then structural stability is improved, but installation and maintenance become inconvenient
Solution Approach 1:
The cooling plate is designed with a detachable mounting mechanism that transitions between a fixed stable state during use and a removable state for maintenance. The detachable connection structure allows the cooling plate to be easily installed and removed without compromising structural stability when attached.
3Reliability
If a complex gas transmission pipe system with multiple fasteners is used, then sealing is improved, but operational complexity increases
Solution Approach 1:
The complex gas transmission pipe system with multiple fasteners and sealing discs is completely removed from the design. The cooling air is delivered directly through simplified openings in the back panel and shoulder straps, eliminating the need for complex piping while maintaining effective cooling through direct air flow paths.

AI summary
A backpack with cooling and temperature-lowering functionality, which includes a backpack main body with a cavity and shoulder straps. A ring-shaped flexible protrusion is set on the back of the backpack main body, upon which is a flexible support for contact with the human back. A chamber is formed between the back of the backpack main body, the ring-shaped flexible protrusion, and the flexible support. A cooling unit is located on the outer side of the ring-shaped flexible protrusion, comprising a housing that is detachably mounted on the backpack main body, a TEC cooling plate located inside the housing, and a fan. The housing has a cold air nozzle that is inserted through the ring-shaped flexible protrusion and extends into the chamber to input cold air, thereby cooling the human back and making the user feel more comfortable.
