Vessel Cap Structure with Detachable Component Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screw-coupling structures for vessel caps require inconvenient repeated rotation to open or close, leading to wastage of cosmetics when using integrated tools like pipettes or mascara sticks, as users must tilt the vessel to access remaining liquid.
Innovation Solution
A cap structure featuring an inner and outer cylindrical cap with a detachable unit, including fixing grooves, guiding surfaces, and elastic members, allowing the component to be locked or released by rotating the outer cap at a predetermined angle without separating the caps from the vessel, enabling efficient use of cosmetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw-coupling structure is used to couple the cap with the vessel, then the cap can be securely attached to the vessel, but the user must inconveniently rotate the cap several times to open or close it
Solution Approach 1:
The cap structure is divided into separate components: an inner cap that couples with the vessel and an outer cap that rotates relative to the inner cap. The detachable unit is segmented into a fixing groove in the inner cap and a corresponding fixing protrusion in the outer cap, allowing independent rotation and locking actions.
Solution Approach 2:
The cap structure transitions from a static screw coupling to a dynamic system where the outer cap can rotate relative to the inner cap. The detachable unit provides dynamic locking and unlocking mechanisms that allow the component to be fixedly attached or separated while the caps remain coupled.
2Ease of operation
If the cap is separated from the vessel to use the integrated component, then the component can be accessed, but the user must tilt the vessel which causes cosmetic wastage
Solution Approach 1:
The integrated component is segmented from the cap structure through the detachable unit, allowing it to be independently separated while the cap remains attached to the vessel. This enables component removal without vessel tilting.
Solution Approach 2:
The detachable unit acts as an intermediary mechanism between the component and the cap. It provides a fixed attachment point that allows the component to be removed from the cap while the cap-stem assembly remains intact on the vessel.
3Reliability
If the component is fixedly attached to the cap, then the component is securely held, but the user cannot separate the component from the cap without separating the cap from the vessel
Solution Approach 1:
The detachable unit provides a dynamic attachment system where the component can be fixedly held during use and then easily separated when needed. The fixing groove and protrusion mechanism allows for secure attachment that can be deliberately disengaged by rotating the outer cap.
Solution Approach 2:
The detachable unit is designed to be self-actuating through the rotation of the outer cap. The elastic member automatically engages the fixing protrusion with the fixing groove, and rotation automatically disengages it, eliminating the need for separate attachment or detachment operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The cap structure allows for simple opening and closing of components, ensuring that integrated tools can be used closely to the vessel floor, minimizing cosmetic wastage and offering versatile design options.

AI summary
Provided is a cap structure of a vessel, which is coupled with the vessel to close or open the vessel. The cap structure includes an inner cap having a cylindrical shape and coupled with an upper end portion of the vessel to open or close the vessel, an outer cap having a cylindrical shape and fitted around an outer-diameter surface of the inner cap such that the outer cap is coupled with the inner cap, a component inserted into the outer cap and the inner cap, and a detachable unit to fixedly couple the component with the inner cap or the outer cap or separate the component from the inner cap or the outer cap without separating the inner cap or the outer cap from the vessel. The cap opens or closes the vessel by fixedly attaching the component to the cap disassembled from the vessel or separating the component from the cap.
