Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paste bottles have limited storage capacity due to the stud structure occupying half the bottle space, leading to quick depletion and inconvenient paste replacement and disposal.
Innovation Solution
A paste bottle with a multistage ejection mechanism, comprising a detachable outer bottle, a replaceable inner bottle, and a multistage ejection mechanism that utilizes screw pairs to maximize space and facilitate easy replacement, featuring a detachable gland, rotary seat with ribs, and a support bar for elliptical inner bottle rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a stud structure is used to eject paste, then paste ejection function is achieved, but paste storage capacity is limited due to occupying half the bottle space
Solution Approach 1:
The ejection mechanism is segmented into multiple stages with multiple screw pairs (first screw pair, second screw pair, third screw pair) arranged at different heights. This segmentation allows the paste seat to be ejected through coordinated rotation of multiple components, maximizing the utilization of bottle internal space and increasing paste storage capacity while maintaining effective ejection function.
2Quantity of substance
If the bottle height is limited to 8-10 cm for portability, then portability is improved, but paste storage capacity is restricted
Solution Approach 1:
The multistage ejection mechanism components (screw sleeves, studs, paste seat) are nested within the bottle structure, with the paste seat sliding within the inner bottle body and multiple screw pairs arranged concentrically. This nested arrangement allows maximum paste storage capacity to be achieved within the limited bottle height of 8-10 cm while maintaining portability.
3Ease of operation
If a fixed inner bottle design is used, then manufacturing simplicity is maintained, but paste replacement convenience is reduced
Solution Approach 1:
The bottle is segmented into a detachable outer bottle and a replaceable inner bottle with the paste seat. The inner bottle can be easily removed and replaced by detaching the outer bottle, allowing convenient paste replacement while maintaining relatively simple manufacturing processes for each component.
Solution Approach 2:
The inner bottle is designed with dynamic replaceability, allowing it to be easily inserted and removed from the outer bottle through the detachable gland mechanism. This dynamic design enables convenient paste replacement without requiring complex manufacturing, as the inner bottle can be produced separately and exchanged by the user.
4Quantity of substance
If the multistage ejection mechanism is added to maximize space utilization, then paste storage capacity is improved, but device complexity increases
Solution Approach 1:
Multiple screw pairs (first, second, and third screw pairs) are merged into a single integrated ejection system that operates through the rotation of the paste seat and coordinated movement of the screw sleeves. This merging approach maximizes space utilization for paste storage while managing the complexity through unified operational control.
Solution Approach 2:
The multistage ejection mechanism enables continuous paste ejection through the coordinated rotation of multiple screw pairs, ensuring that the paste seat can be progressively ejected to maximize the utilization of the bottle's internal space for paste storage while maintaining a continuous ejection action.

AI summary
A paste bottle with a multistage ejection mechanism is provided, the bottle includes an outer bottle, a replaceable inner bottle, and a multistage ejection mechanism. An upper end of the outer bottle is provided with a detachable gland, a lower end of the outer bottle is connected with a rotary seat which can rotate circumferentially. An upper end of the inner bottle body is mounted in alignment with the outer bottle and forms an accommodating area with the outer bottle. The multistage ejection mechanism is arranged in the accommodating area. The multistage ejection mechanism includes a middle stud, an intermediate screw sleeve and an outer screw sleeve. The multistage ejection mechanism can effectively utilize space inside the inner bottle.
