Solution Overview
Problem
Conventional aerosol-generating devices face challenges in manufacturing a heater assembly that efficiently heats aerosol-forming substrates while being easy to produce and well-insulated from other device components, leading to high costs and complex fixation solutions.
Innovation Solution
A heater assembly featuring an electrically insulating element and an integral metal sheet with a central heating portion and anchoring legs, where the anchoring legs are bendable and extend from the central heating portion to securely anchor the heater, providing both heating and insulation, and are made from materials like stainless steel for durability and resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fixation solutions are used to anchor the heater to the device, then the heater is securely mounted, but the manufacturing complexity and cost increase
Solution Approach 1:
The heater and anchoring legs are integrally formed as a single component, combining the heating function and mounting function into one unified structure. This eliminates the need for separate fixation elements and simplifies the overall assembly while maintaining secure mounting through the bendable legs that anchor to the insulating element
2Use of energy by moving object
If the heater is well-insulated from device components, then power consumption decreases, but the insulation complexity increases
Solution Approach 1:
The insulating element serves multiple functions simultaneously: it provides thermal insulation to reduce power consumption, provides electrical insulation for safety, and serves as the anchoring surface for the bendable legs to attach the heater securely. This multi-functionality eliminates the need for separate insulation and mounting structures
