Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inhalers for large animals, such as horses, require robust, complex, and expensive construction, are prone to soiling, and are difficult to operate, especially when used in rough conditions or with gloves, and existing human inhalers are unsuitable due to the need for larger doses and ergonomic challenges.
Innovation Solution
A compact, ergonomic inhaler design with a fixed reservoir, an inclined discharge nozzle, and an actuating lever, featuring a discharge direction angled relative to the central axis, and a modular insert system for easy handling and precise dosing, including a chamber for aerosol storage and a nostril adapter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If inhalers are designed to be robust for use in large animals, then reliability improves, but device complexity and manufacturing cost increase
Solution Approach 1:
The inhaler is divided into separate functional components: a removable reservoir assembly containing the medicament and valve, a separate actuating lever mechanism, and a fixed housing with aerosol delivery components. This segmentation allows each component to be optimized independently for reliability while simplifying the overall device complexity and reducing manufacturing costs.
2Reliability
If inhalers are designed with robust construction for large animals, then reliability improves, but ease of operation deteriorates
Solution Approach 1:
The actuating lever is designed to move through a large arc from a rearmost position to a forward position, providing dynamic mechanical advantage that enables easy actuation even with gloved hands or in rough conditions. This dynamic movement mechanism transforms small user input forces into reliable valve actuation.
3Ease of operation
If the reservoir is made movable for actuation, then ease of operation improves, but manufacturing precision requirements increase
Solution Approach 1:
Instead of moving the reservoir for actuation, the invention inverts the approach by keeping the reservoir fixed and moving the actuating lever. The lever connects to the valve mechanism and actuates it through its arcuate movement, eliminating the need for precise movable reservoir connections while maintaining ease of operation.
4Manufacturing precision
If the discharge nozzle is aligned with the central axis, then manufacturing precision is improved, but aerosol delivery effectiveness deteriorates
Solution Approach 1:
The discharge nozzle is deliberately angled relative to the central axis of the reservoir, creating an asymmetric configuration. This asymmetry optimizes aerosol delivery by directing the spray toward the animal's respiratory tract more effectively, improving productivity while the angular relationship is maintained within acceptable manufacturing tolerances.

AI summary
An inhaler is proposed, particularly for a horse, having a reservoir for dispensing a medicament preparation held under excess pressure, with a discharge nozzle for forming an aerosol of the medicament preparation and with a chamber for holding and temporarily storing the aerosol, which comprises or forms, on the outlet side, a respiratory orifice adapter for a respiratory orifice, particularly a nostril, while according to a first aspect the reservoir is secured in position, at least in the axial direction, according to a second aspect the discharge nozzle has a direction of discharge which is inclined by more than 5° and less than 50° relative to a central axis of the reservoir or a direction of actuation for dispensing the aerosol, and according to a third aspect the reservoir comprises a dispensing valve which is arranged at the top in the position of use of the inhaler.
