Portable heating pad assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery-powered heating pads for vehicle and stroller seats lack rechargeability via alternating current, direct current, and solar power sources, and do not provide selective lighting or multi-seat heating capabilities.
Innovation Solution
A rechargeable battery-powered heating pad assembly with multiple charging options (AC, DC, and solar) and integrated lighting, along with the ability to connect multiple heating pads for simultaneous warming of multiple seats or hand warmers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a battery-powered heating pad is designed for portability, then ease of operation is improved, but the ability to recharge through multiple energy sources (AC, DC, solar) is lacking
Solution Approach 1:
The heating pad system incorporates multiple charging interfaces that accept AC power cords, DC power cords, and solar panel connections. This multi-functionality allows the same portable heating pad to be recharged through various energy sources, resolving the contradiction between portability and adaptability by enabling the device to maintain portability while gaining versatile recharge capabilities through integrated multiple charging ports and compatible connectors.
2Device complexity
If a heating pad provides only heating function, then device complexity is reduced, but adaptability for different user needs (heating and lighting) is limited
Solution Approach 1:
The heating pad integrates both heating elements and LED lighting components within the same device. The control system allows users to select between heating mode, lighting mode, or combined operation. This multi-functional design resolves the contradiction by maintaining relatively simple device architecture while providing adaptable functionality for different user needs through integrated heating and lighting systems with selectable operational modes.
Solution Approach 2:
The heating pad incorporates a control system that dynamically switches between different operational modes (heating only, lighting only, or combined). This dynamic adaptability allows the device to adjust its functionality based on user requirements, resolving the contradiction between simplicity and versatility by providing multiple functions that can be selectively activated rather than continuously operating all components.

AI summary
A portable heating pad assembly for on-demand heating of a seat of a vehicle or a stroller includes a housing, which defines an interior space. A battery, which is rechargeable, is positioned in the interior space. A power cord, which is operationally engaged to the battery, is attached to and extends from the housing. A plug of the power cord is engageable to a receptacle of a source of electrical current to charge the battery. A power cable, which is operationally engaged to the battery, is attached to and extends from the housing. A heating pad is operationally engaged to the power cable and can be selectively positioned on a seat of a vehicle and a seating surface of a stroller. The heating pad thus can warm a child seated in the seat of the vehicle or in the stroller.
