Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing discharge container designs result in varying discharge amounts of contents across different positions, making it difficult to form modeled objects with high accuracy and reproducibility on a modeling surface.
Innovation Solution
A discharge container with a stem that moves downward, a diffusion chamber, and a diffusion member that diffuses contents radially, ensuring even distribution through central and outer forming holes, preventing variations in discharge amount and enhancing reproducibility and accuracy of modeled objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If liquid outlet holes are arranged at intervals in the circumferential direction by fixing legs, then the contents can be discharged through multiple holes, but the discharge amount varies depending on each position along the circumferential direction
Solution Approach 1:
The top wall portion is divided into multiple regions (central region and outer region) with different types of forming holes (central forming holes and outer forming holes). This segmentation allows different regions to contribute differently to the overall discharge, balancing the discharge amount across all positions and eliminating variations that would occur with uniform hole distribution.
Solution Approach 2:
Different regions of the top wall portion are given different local characteristics: the central region has central forming holes while the outer region has outer forming holes. This local differentiation ensures that each region discharges contents according to its specific capacity, achieving uniform discharge amounts across all positions despite their different locations.
2Productivity
If contents are discharged through multiple liquid outlet holes at different positions, then the discharge capacity is increased, but the discharge amount varies at different discharge positions
Solution Approach 1:
The forming holes are segmented into central forming holes in the central region and outer forming holes in the outer region. This segmentation allows the system to maintain high discharge capacity through multiple holes while ensuring that each hole discharges a consistent, balanced amount, thereby achieving both high productivity and reliable reproducibility.
Solution Approach 2:
The parameters of the forming holes (position, type, and distribution) are changed across different regions. Central forming holes and outer forming holes have different parameters that are optimized for their respective locations, ensuring uniform discharge amounts while maintaining high overall discharge capacity.
3Manufacturing precision
If a diffusion member is added to diffuse contents radially, then the discharge amount uniformity is improved, but the device complexity increases
Solution Approach 1:
Instead of using a complex diffusion member, the system segments the top wall portion into central and outer regions with different forming holes. This structural segmentation naturally achieves radial diffusion of contents without requiring additional diffusion components, thereby improving discharge uniformity while avoiding increased device complexity.
Solution Approach 2:
The top wall portion itself acts as an intermediary structure that facilitates radial diffusion of contents from the central region to the outer region through its differentiated forming hole arrangement. This eliminates the need for separate diffusion members while achieving the desired diffusion effect.
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 container ensures consistent discharge of contents, allowing for the formation of modeled objects with high accuracy and reproducibility by evenly distributing the contents across the modeling surface, preventing variations in discharge amount and improving operational reliability.
Implementation Method 1
The diffusion member is configured to diffuse the contents from the stem outward in the radial direction through a gap between the diffusion member and the diffusion wall portion

AI summary
A discharge container (1) includes a container body (2) that contains contents, a discharger (4) that has a stem (3), an exterior portion (5) that has a top wall portion (40) having a forming hole (45), and that is configured to discharge the contents passing through the forming hole onto a modeling surface (48), and a diffusion wall portion (50) that defines a diffusion chamber (52) for supplying the contents from the stem to the forming hole, between the diffusion chamber and a supply surface (49) of the top wall portion. The forming hole includes a central forming hole (46) formed in a central region of the top wall portion and an outer forming hole (47) formed in an outer region. The diffusion chamber internally has a diffusion member (80) located so as to face the diffusion wall portion and located so as to overlap a whole region of at least the central region in the top wall portion in the upward-downward direction, in a plan view when viewed in a container axis direction. The diffusion member is configured to diffuse the contents supplied from the stem outward in the radial direction through a gap between the diffusion member and the diffusion wall portion.
