Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smoking devices struggle to efficiently switch between using solid smoking materials in a heat-not-burn manner and liquid materials in a vaping manner, often requiring separate devices or complex mechanisms for each mode, which can be inconvenient and less hygienic.
Innovation Solution
A smoking device designed to accommodate both solid and liquid capsules, with integrated heating elements and control components that allow seamless switching between heat-not-burn and vaping modes, using electrical resistive or magnetic induction heating, and featuring collapse-prevention elements to maintain capsule integrity during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single device is designed to accommodate both solid and liquid capsules, then versatility and convenience are improved, but device complexity increases
Solution Approach 1:
The heating element is designed with a universal structure that can effectively heat both solid smoking materials and liquid vaping materials through a single component, eliminating the need for separate heating mechanisms for each capsule type
Solution Approach 2:
The device incorporates a movable plunger that can be dynamically adjusted to different positions depending on whether a solid or liquid capsule is inserted, allowing the heating element to adapt its configuration to match the specific capsule type and maintain optimal heating performance
2Ease of operation
If separate devices are used for solid and liquid materials, then heating efficiency is maintained, but ease of operation and hygiene deteriorate
Solution Approach 1:
The device automatically detects the type of capsule inserted (solid or liquid) and self-adjusts the plunger position and heating parameters accordingly, eliminating the need for manual switching while maintaining optimal heating performance for each capsule type
Solution Approach 2:
The device incorporates sensing mechanisms that detect capsule characteristics and provide feedback to the control system, which then adjusts heating parameters and plunger position to maintain consistent heating performance across different capsule types
3Strength
If mechanical pressure is applied to flatten the capsule, then contact with heating element is improved, but capsule structure integrity may deteriorate
Solution Approach 1:
The device applies mechanical pressure locally only to the specific region of the capsule that requires flattening for optimal heating contact, while leaving the rest of the capsule structure intact and undisturbed, thus maintaining overall capsule integrity
Solution Approach 2:
The device uses a magnetically actuated plunger that replaces direct mechanical contact systems, allowing pressure to be applied through magnetic fields which can be precisely controlled to achieve the necessary flattening force without excessive mechanical stress that could damage the capsule

AI summary
Apparatus and methods are described for use with a capsule that contains a smoking material containing one or more active agents and a metallic foil. A smoking device configured to receive the capsule, includes a capsule-receiving chamber configured to receive the capsule, a first set of spring electrodes disposed around a circumference of the capsule-receiving chamber at a first axial location, and a second set of spring electrodes disposed around a circumference of the capsule-receiving chamber at a second axial location. A control component is configured to heat the smoking material by driving an electrical current from the first set of spring electrodes to the second set of spring electrodes along the metallic foil. Other applications are also described.
