Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current container tops for volatile substance evaporators are inefficient in plastic usage, leading to reduced rigidity and increased risk of deformation, which affects product integrity and production line efficiency, and are not reusable, posing environmental and economic concerns.
Innovation Solution
A bell-shaped top design with a hollow upper part, middle zone with anchoring elements, and a flared skirt featuring inner and outer ribs that provide structural support while minimizing material usage, allowing for reduced weight and enhanced robustness to prevent deformation and facilitate mass production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of stationary object
If the thickness of the walls of the top is reduced to reduce plastic consumption and weight, then plastic usage and weight are reduced, but the resistance capacity and rigidity are compromised leading to deformations
Solution Approach 1:
The top is divided into multiple functional zones: an upper part for housing the wick, a middle zone with anchoring elements, and a lower skirt portion. This segmentation allows each zone to be optimized independently for its specific function while using material efficiently.
Solution Approach 2:
Different portions of the top have different wall thicknesses and structural characteristics tailored to their specific functional requirements. The middle zone has greater thickness for anchoring stability, while the upper and lower portions can have reduced thickness where full strength is not required, optimizing material usage.
Solution Approach 3:
The invention introduces a third dimension by adding ribs that extend both inward and outward from the top body. These ribs create a three-dimensional structural framework that provides reinforcement without increasing the overall footprint or requiring uniformly thicker walls.
2Loss of substance
If the thickness of the walls of the top is reduced to reduce plastic consumption, then plastic consumption is reduced, but deformations occur during threading and insertion that cause damage to product or production line
Solution Approach 1:
The ribs are integrated into the top structure during manufacturing, providing pre-established reinforcement points that prevent deformations during subsequent threading and insertion operations. This preliminary structural preparation ensures reliable performance throughout the production process.
Solution Approach 2:
The ribs extend in multiple dimensions from the top body, creating a three-dimensional reinforcement framework that resists deformation during threading operations. This dimensional approach provides structural support without requiring uniformly thicker walls.
3Strength
If ribs are added to strengthen the top structure, then resistance capacity and rigidity are improved, but the complexity of the top design increases
Solution Approach 1:
The ribs are designed to coincide with or integrate with existing structural features of the top, such as the anchoring elements in the middle zone. This merging of functions allows the ribs to provide reinforcement while serving dual purposes, reducing overall design complexity.
Solution Approach 2:
The ribs serve multiple functions simultaneously: they provide structural reinforcement, define the geometry of the top, and can integrate with anchoring mechanisms. This multi-functionality reduces the need for separate components and simplifies the overall design.

AI summary
Top for container comprising a bell-like body suitable for housing a wick that protrudes from the mouth of a container, the top may present in the upper part a shape suitable for housing part of said wick, a middle zone which on the internal face has means of anchoring to the container and, in the lower zone presents a skirt, in the inner lower zone of the top are some stiffeners which aligns with some outer stiffeners and provide robustness to the part achieving a lower consumption of manufacturing material.
