Rotating Broomstick Cap With Integrated Hanging Eyelet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing broomstick caps, composed of two separate parts, face high production costs and are prone to detachment due to thermal variations and user stresses, posing safety risks as they can become loose over time.
Innovation Solution
A single-piece cap design for the broomstick with a rotatable coupling mechanism, featuring a circular notching around the broomstick's circumference and a complementary protuberance inside the cap, allowing 360° rotation while preventing translation and detachment, thus eliminating the need for complex molds and assembly machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cap is composed of two separate parts assembled by mechanical interference, then the cap can be rotated with respect to the broomstick, but the production cost increases due to requiring two molds and assembly machines
Solution Approach 1:
The invention merges the two separate cap parts into a single integrated cap structure. The cap is formed as one piece with an internal cavity that receives the broomstick end, eliminating the need for separate superior and inferior parts. This single-piece construction maintains the rotatable connection while significantly simplifying the device structure and reducing production complexity.
Solution Approach 2:
The invention segments the functional requirements: the cap body provides protection and structure, while the internal cavity provides the rotatable connection mechanism. By integrating these functions into a single piece rather than separate components, the design achieves rotatability without requiring multiple parts or assembly steps.
2Ease of operation
If the cap is composed of two separate parts assembled by mechanical interference, then the cap can be rotated with respect to the broomstick, but the production cost increases due to requiring complex molds and double injection processes
Solution Approach 1:
The invention combines the molding process into a single operation. The cap is molded as one piece in a single mold, eliminating the need for complex double injection processes or separate molding operations for superior and inferior parts. This dramatically simplifies the manufacturing process and reduces equipment requirements.
3Ease of manufacture
If the cap is inserted on the broomstick by mechanical interference, then the cap can be assembled during production, but the seal loses efficiency over time due to thermal variations and user stresses causing the cap to withdraw
Solution Approach 1:
The invention incorporates a sealing element within the cap's internal cavity that compensates for thermal expansion and contraction. The seal is designed to maintain continuous contact with the broomstick end despite temperature variations and user stresses, preventing the cap from withdrawing. This beforehand cushioning of thermal and mechanical effects ensures long-term reliability.
Solution Approach 2:
The invention uses a flexible sealing element (such as a rubber or elastomeric ring) within the cap structure. This flexible seal adapts to dimensional changes in the broomstick end caused by thermal variations and mechanical stresses, maintaining the seal and preventing cap withdrawal over time.

AI summary
A broomstick for a broom includes a cap having a first part that is connected to an end of the broomstick and a second part provided with a hanging element configured to hang the broomstick to a wall. The connection between the first part of the cap and the broomstick is rotatable in such a way that the cap can rotate with respect to the broomstick and vice-versa, wherein, further, the cap is in a single piece in such a way that a rotation of the first part of the cap corresponds to a rotation of the second part of the cap.
