Aerosol Canister Case with Rotating Locking Cap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol canisters lack a secure and easy-to-use attachment mechanism to the user's body, making it difficult to access the contents quickly while preventing accidental dispensing, especially in personal defense scenarios where rapid deployment is crucial.
Innovation Solution
A case design with a rotating cap that locks and unlocks, featuring a body with cutouts and gussets that engage to allow axial movement for dispensing and prevent it when locked, combined with attachment means like ring, clip, or snap ring attachments for securing to clothing or accessories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rotating cap mechanism is added to lock and unlock the aerosol canister, then the reliability of preventing unintentional dispensing is improved, but the device complexity increases
Solution Approach 1:
The cap is designed to rotate between locked and unlocked positions, transforming a static closure into a dynamic mechanism. The gussets rotate with the cap to engage or disengage from cutouts, providing automatic locking and unlocking functionality that prevents unintentional dispensing while maintaining operational simplicity
Solution Approach 2:
The gussets are integrated into the cap structure, with each gusset containing a cutout that nests within the body's corresponding features. This nested design allows the locking mechanism to be incorporated within the existing cap and body structure without adding external components, thus improving reliability while minimizing increased complexity
2Ease of operation
If the cap is made displaceable in axial direction for dispensing, then the ease of operation is improved, but the reliability of preventing accidental dispensing worsens
Solution Approach 1:
The cap transitions from a static to a dynamic component that can both rotate for locking and displace axially for dispensing. The rotational movement of gussets relative to the body creates locked/unlocked states, while axial displacement of the entire cap assembly enables content dispensing, thus achieving both ease of operation and reliability
Solution Approach 2:
The cap mechanism is segmented into independent functional elements: the cap body that displaces axially for dispensing, and the gussets that rotate for locking. This segmentation allows the axial displacement function and rotational locking function to operate independently, ensuring that accidental axial movement cannot occur without corresponding gusset rotation to the unlocked position
3Reliability
If attachment means are added to secure the canister to the user's body, then the reliability of secure carrying is improved, but the device complexity increases
Solution Approach 1:
The cap serves multiple functions: it closes the aerosol canister, provides a rotating locking mechanism, and incorporates attachment means for securing to the user's body. By making the cap multi-functional, the attachment capability is added without requiring a separate attachment device, thus improving reliability of secure carrying while minimizing the increase in device complexity
