Body-Heat Backpack Compartment for Freeze-Protected Accessories
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Backpack accessories such as mobile phones or hydration tubes can freeze in cold weather due to low temperatures, necessitating the use of multiple specific covers or insulation materials, which is inconvenient and inefficient.
Innovation Solution
A backpack with a body-heated compartment formed by wind and heat-insulating material, sealed with a flexible seal that contacts the user to retain body heat, using a combination of heat transfer and insulating materials to maintain items above freezing temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple specific insulation covers are used for different accessories, then protection against freezing is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent merges the insulation function into a single integrated backpack structure that protects all accessories simultaneously. The wind and heat insulating material forms a body-heated compartment that encompasses multiple accessories (mobile phone, hydration tube, mouthpiece) within one unified thermal protection zone, eliminating the need for separate insulation covers for each item.
Solution Approach 2:
The backpack's body-heated compartment serves as a universal insulation solution for all types of accessories. The single compartment design with integrated sealing provides multi-functional protection for various items (electronic devices, hydration systems, etc.) that would otherwise require different specialized covers.
2Reliability
If multiple specific insulation covers are used for different accessories, then protection against freezing is improved, but ease of operation deteriorates
Solution Approach 1:
The patent merges the insulation function into a single integrated backpack structure that protects all accessories simultaneously. The wind and heat insulating material forms a body-heated compartment that encompasses multiple accessories (mobile phone, hydration tube, mouthpiece) within one unified thermal protection zone, eliminating the need for separate insulation covers for each item.
Solution Approach 2:
The backpack utilizes the user's own body heat as the heating source. The body-heated compartment leverages the natural thermal energy from the user's body to maintain temperature, creating a self-sustaining thermal system that requires no external power source or active heating mechanism.
3Temperature
If wind and heat insulating material is used to form a body heated compartment, then temperature maintenance is improved, but heat transfer to accessories deteriorates
Solution Approach 1:
The patent applies different material properties in different locations within the backpack structure. The wind and heat insulating material is positioned to maintain temperature in the compartment, while heat transfer material is strategically placed at contact points with accessories to ensure efficient heat transfer where needed, creating localized thermal zones with optimized properties.
Solution Approach 2:
The backpack employs a composite material structure combining wind and heat insulating material with heat transfer material. This composite construction allows the system to simultaneously achieve thermal insulation for temperature maintenance and efficient heat transfer to accessories, resolving the contradiction between the two opposing requirements.
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 effectively maintains items in the backpack above freezing temperatures by utilizing body heat, ensuring consistent functionality of accessories in cold conditions without the need for multiple insulation covers.
Implementation Method 1
A backpack with a compartment heated by body heat from a user of the backpack
Implementation Method 2
Some examples of the disclosure provide for a heat transfer material that allows body heat to pass through
Data Source
AI summary
A backpack may include a wind and heat insulating material, the wind and heat insulating material forming a body heated compartment. The backpack may further comprise a seal. The seal may be connected to the body heated compartment and configured to contact a user of the backpack such that the body heated compartment is at least partly sealed against the user.
