Angled Spring Cap Attachment for Pharmaceutical Handset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handsets for delivering pharmaceutical substances face challenges in securely attaching and releasing the cap, which can lead to loss and inefficient sealing, particularly due to limitations in spring design and attachment mechanisms.
Innovation Solution
The design incorporates a spring with two spring arms attached at transversely spaced fastening points, featuring an angled progression that allows for a stable and secure attachment to the housing, enabling the cap to be swiveled downward under the housing floor, providing an improved spring effect and lengthening the effective spring path, while maintaining the cap secured against loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring attachment mechanism is used to secure the cap to the housing, then the cap can be attached and released, but the cap may be lost and sealing efficiency is reduced
Solution Approach 1:
The spring attachment mechanism is extended downward below the housing floor level, creating a three-dimensional attachment path that prevents cap loss. The spring's attachment region protrudes downward from the housing floor, and the cap's attachment element engages with this extended region, ensuring the cap cannot be accidentally lost while maintaining secure sealing.
Solution Approach 2:
The spring is divided into two separate spring arms that are spaced apart and attached to the cap at different locations. This segmentation provides stable attachment while allowing the cap to be securely held and easily removed when needed, preventing both cap loss and maintaining sealing efficiency.
2Stability of the object's composition
If the spring path is lengthened to improve spring effect, then attachment stability improves, but device complexity increases
Solution Approach 1:
The spring path is extended in the vertical dimension by protruding downward below the housing floor. This lengthens the effective spring path and improves spring effect and attachment stability without adding horizontal complexity or requiring additional components.
Solution Approach 2:
The attachment region is integrated directly into the spring structure itself, eliminating the need for separate attachment components. The spring arms and attachment region form a unified structure that provides both the spring effect and the attachment function, reducing overall device complexity.

AI summary
The invention relates to a handset (1) for delivering a pharmaceutical substance, with a housing (2) that exhibits a mouthpiece (8), wherein the mouthpiece (8) can be sealed with a cap (9), and the cap (9) is attached to the housing (2) by means of a spring (16), and can be swiveled around a swivel axis (x) to release the mouthpiece (8). In order to further improve a handset of the kind in question, in particular as relates to attaching the cap to the handset, it is proposed that the spring (16) have an angled progression in a top view, in which the swivel axis (x) is imaged as a line.
