Pocket Hand Warmer Sleeve With Graspable Heating Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand warmers are not efficient in heating and retaining heat for extended periods while being portable enough for outdoor use during sports or activities like football and golf.
Innovation Solution
A hand warmer design featuring a tubular sleeve with a handlebar-shaped heating element that can be grasped directly, secured at both ends, and surrounded by self-closing fabric to retain heat, powered by a rechargeable lithium battery with adjustable heat settings and a heat capture fabric to extend battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a traditional hand warmer design is used, then portability is achieved, but heating efficiency and heat retention for extended periods is insufficient
Solution Approach 1:
The heating system is divided into multiple heating zones (first heating element in the first chamber, second heating element in the second chamber) that can operate independently or simultaneously, allowing optimized heat distribution and extended operational duration through sequential or concurrent heating
Solution Approach 2:
The heating elements are positioned within chambers that are nested within the tubular sleeve structure, with the first heating element in a first chamber and the second heating element in a second chamber, creating a nested configuration that maximizes space utilization and heat retention
2Power
If a rechargeable lithium battery with adjustable heat settings is added, then heating efficiency is improved, but device complexity increases
Solution Approach 1:
The hand warmer incorporates adjustable heat settings that allow dynamic control of heating power, enabling users to select between different heating intensities (first heating element, second heating element, or both) based on environmental conditions and personal preference
Solution Approach 2:
The heating system is designed to provide multiple heating modes through a single battery-powered unit, where the same battery can power different heating elements at different power levels, making the device adaptable to various heating needs without requiring multiple separate devices
