Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for inhaling powder-type substances lack operational safety and efficient counting mechanisms for substance containers.
Innovation Solution
A device with a pivotable closure cap that simultaneously acts on both insertion mechanisms, allowing for safe operation and a counter mechanism to track the number of emptied or non-emptied substance containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple substance containers are provided in the device, then the quantity of substance available increases, but the device complexity increases
Solution Approach 1:
The device is divided into multiple independent substance container units that can be individually handled and replaced. Each container is a separate module that can be inserted or removed without affecting the entire device structure, allowing the quantity of substance to be increased through simple addition of modules rather than redesigning the whole system.
Solution Approach 2:
The device is designed with universal interfaces and standardized container formats that can accommodate different types and quantities of substance containers. The same basic device structure can handle various numbers of containers through a unified mechanism, reducing overall device complexity while maintaining flexibility in substance quantity.
2Reliability
If insertion mechanisms are provided for opening substance containers, then the reliability of substance dispensing improves, but the device complexity increases
Solution Approach 1:
The insertion mechanism is designed to automatically perform the opening action when the substance container is inserted into the device. The mechanical interface itself triggers the opening process without requiring separate manual operations or additional control systems, thereby improving reliability through consistent automatic operation while minimizing added complexity.
Solution Approach 2:
The insertion and opening functions are merged into a single integrated mechanism. The same structural elements that receive and position the substance container also perform the opening action, eliminating the need for separate insertion and opening mechanisms and reducing overall device complexity while maintaining reliable operation.
3Loss of information
If a counter mechanism is added to track substance containers, then the loss of information is reduced, but the device complexity increases
Solution Approach 1:
The counter mechanism replaces complex mechanical tracking systems with simpler electronic or optical sensing elements that detect the presence and number of substance containers. This substitution reduces the mechanical complexity of the counting system while providing accurate real-time information about the quantity of containers in the device.
Solution Approach 2:
The counter mechanism provides continuous feedback information about the number of substance containers to the user interface or control system. This feedback loop allows the device to automatically track and manage container quantities without requiring complex manual tracking mechanisms, reducing overall system complexity while preventing information loss.

AI summary
A device for inhaling powder-type substances includes a mouthpiece, an insertion unit having a retaining part with an insertion means for opening a sub-region in a substance container containing the substance, and a discharge channel for the substance leading to the mouthpiece. In order to advantageously further improve a device of this type, it is proposed that two insertion units are provided, having preferably two retaining parts, which are separate from one another, which each have an insertion means, and with which the substance container can be opened in intersecting or opposing insertion directions. The device for inhaling powder-type substances also includes a plurality of substance containers that can be moved successively into an emptying position. The number of emptied or non-emptied substance containers can be displayed via a counter.
