Detachable Battery Jacket with Dynamic Heating Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Insulated jackets often fail to maintain optimal body temperature, either leaving users cold if insulation is too thin or overheating if it is too thick, lacking a reliable and adjustable heat source.
Innovation Solution
An electrically heated jacket with a rechargeable battery pack and detachable battery holder, featuring a heater array and control system that allows users to adjust temperature settings, powered by lithium-based battery cells and controlled via a user-actuated button with display indicators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If insulation is made thicker to provide more warmth, then warmth is improved, but the user may overheat
Solution Approach 1:
The jacket incorporates electric heating elements with variable power output that can be dynamically adjusted through control switches. This allows the thermal properties of the jacket to change in real-time based on user needs, transforming a static insulation system into a dynamic thermal regulation system that can adapt to different temperature requirements without overheating the user.
Solution Approach 2:
The heating system allows users to change the power output parameter of the heating elements through control switches. By varying the electrical power supplied to the heating elements, the jacket can adjust its thermal output to maintain optimal comfort levels, preventing both cold and overheating conditions.
2Adaptability or versatility
If insulation is made thinner to prevent overheating, then temperature regulation is improved, but the user may be cold
Solution Approach 1:
The electric heating system provides dynamic thermal adjustment capability, allowing the jacket to compensate for thinner insulation. The heating elements can be activated and adjusted to provide additional warmth when needed, enabling the use of lighter, more breathable insulation materials while maintaining adequate warmth through active heating control.
3Use of energy by moving object
If a battery pack is integrated into the garment body, then power supply is improved, but the garment complexity increases
Solution Approach 1:
The battery pack is designed as a separate, detachable unit that connects to the garment body through external interfaces. This segmentation allows the power supply system to be independent from the garment structure, simplifying the overall design by enabling easy attachment and removal of the battery pack without complicating the garment's integrated structure.
Solution Approach 2:
The battery pack is extracted from the garment body as a separate component rather than being integrated within it. This extraction simplifies the garment structure by removing the complexity of internal battery housing and wiring, while still providing reliable power supply through an external connection interface that maintains electrical connectivity.
4Ease of operation
If a detachable battery holder is used, then ease of battery replacement is improved, but connection reliability may worsen
Solution Approach 1:
The battery pack contains an integrated battery holder that nests the battery cells within a structured housing. This nested design provides mechanical protection and stable electrical contacts while maintaining the ability to detach the entire battery pack unit from the garment, combining connection reliability with ease of replacement.
