Container Cap with Incision-Formed Ring Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional container caps are prone to separation, loss, and soiling when dropped, leading to environmental pollution due to complex designs and difficult manipulation required for closure.
Innovation Solution
A cap design featuring a ring member connected to the main body via incision lines and connecting pins, allowing the cap to remain attached to the container even when opened, using a simple manufacturing process like injection molding or rotary cutting to form incision lines for easy separation and reattachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cap is completely separated from the container when opened, then the cap can be easily removed and disposed of, but the cap is prone to being dropped, soiled, lost, and causing environmental pollution
Solution Approach 1:
The cap is divided into a main body and a ring member that are separable yet remain connected through incision lines. This segmentation allows the cap to be opened easily while maintaining connection to prevent loss and soiling.
Solution Approach 2:
The ring member is nested within the container opening while the main cap body remains accessible for removal. This nesting arrangement allows the cap to be partially separated for easy opening while the ring member stays attached to prevent complete separation and loss.
2Reliability
If complex connecting structures are used to keep the cap attached to the container, then the cap remains connected and prevents loss, but the design becomes complex and requires difficult physical manipulation for closure
Solution Approach 1:
The incision lines provide dynamic connectivity - the cap can be easily separated when opened but remains attached when closed. This dynamic behavior achieves reliable connection without complex permanent structures.
Solution Approach 2:
The incision lines create flexible connection paths that allow the cap to move freely when opened while maintaining attachment. This flexibility achieves reliable connection without rigid complex structures.
3Reliability
If additional barrier structures are added to prevent cap separation, then the cap remains attached, but the manufacturing process becomes more complex and expensive
Solution Approach 1:
The incision lines are integrated directly into the cap structure during molding, merging the attachment function with the cap body itself. This eliminates the need for separate barrier structures and keeps manufacturing simple.
Solution Approach 2:
The incision lines serve multiple functions: they allow easy opening, maintain attachment to prevent loss, and are manufactured as part of the standard cap molding process. This multi-functionality achieves reliable attachment without additional manufacturing complexity.

AI summary
A cap for a container is formed so that the cap has a top plate and a circular sidewall. Two opposite sides of the circular sidewall circularly connect to each other, one periphery of the circular sidewall connecting to one surface of the top plate forming a closed end, and another periphery of the circular sidewall at an opposite side of the closed end forms an opened end. Incisions are in the circular sidewall. The incisions form a ring member located at the opened end of the cap separated from a main body of the cap by a first incision and a second incision between the opened end of the main body and the ring member.
