Removable Battery Heated Insole Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heated insoles with internal batteries have limited battery life, requiring users to remove and recharge them, which is inconvenient for prolonged use in cold weather conditions.
Innovation Solution
A battery-powered insole design allows for easy removal and replacement of batteries without taking off the insole, featuring a frame with a pivoting connector for energy transfer and a cushioned battery pack that can be recharged separately, enabling continuous warmth without interrupting activity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the battery is made internal and integrated into the insole, then the heating function is provided continuously, but the battery life is limited and recharging requires removing the insole from the shoe
Solution Approach 1:
The battery is segmented from the insole body, allowing it to be removed and replaced independently. The insole contains a battery receptacle that accepts external battery packs, enabling users to swap batteries without removing the entire insole from the shoe. This segmentation resolves the contradiction by maintaining continuous heating capability while enabling easy battery replacement.
Solution Approach 2:
The battery is extracted from the integrated insole structure and made into a separate, removable component. The insole is designed with a battery receptacle that can accommodate external battery packs. This extraction allows the battery to be replaced independently, solving the problem of limited battery life without compromising the convenience of use.
2Ease of operation
If the battery is made removable from the insole, then recharging becomes easier, but the connection between battery and heating element may become less stable
Solution Approach 1:
The battery pack is designed to nest within the insole's battery receptacle, creating a compact and secure fit. The battery pack includes a housing that receives the battery and positions it correctly within the receptacle, ensuring stable electrical connections through aligned contact points. This nesting approach maintains reliability while enabling easy replacement.
Solution Approach 2:
The battery pack housing acts as an intermediary between the removable battery and the insole's heating elements. It provides a stable mechanical and electrical interface, ensuring reliable power transfer while allowing the battery to be easily inserted and removed. The housing includes contact points that mate with corresponding contacts in the receptacle, maintaining connection stability.
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
Enables users to maintain warmth without the hassle of frequent recharging, as the battery can be swapped or recharged on the go, providing extended use in cold conditions without disrupting comfort or functionality.
Implementation Method 1
The heating assembly may include a heating member and a connector, in addition to the frame. The connector of the heating assembly may be operably coupled to the frame, and functions to transfer energy from the battery to the heating member.
Implementation Method 2
The heating member may include a heater panel and a conductive ribbon that transfers energy along a length of the insole to the heater panel.
