Rotatable Dental Material Container with Segmented Holders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing dental material containers require a strong force to open, leading to a risk of dental ceramic molded bodies falling and breaking when being removed, as the cap must be pulled out forcefully.
Innovation Solution
A dental material container design featuring a rotatable cap with internal holders that form a continuous space with the container body, allowing the dental material to be easily extracted by rotating the cap and preventing it from falling back into the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cap is securely fitted into the container body to seal the dental materials, then the sealing performance is improved, but the ease of operation deteriorates because a strong force is required to open the container
Solution Approach 1:
The cap is designed to rotate relative to the container body, transforming the static sealed structure into a dynamic one. The rotation mechanism allows the cap to move from a sealed position to an open position, enabling easy operation while maintaining sealing when closed. The continuous space formed by holders during rotation ensures smooth transition without requiring strong pulling force.
2Ease of operation
If the cap is pulled out strongly to open the container, then the ease of operation improves, but the reliability deteriorates because the dental ceramic molded body may fall and break
Solution Approach 1:
The holders are pre-positioned to support the dental ceramic molded body before opening occurs. The first holders in the container body and second holders in the cap are arranged to form a continuous support space during rotation, preventing the material from falling or breaking before the container is fully opened.
Solution Approach 2:
The holders act as intermediary elements between the cap and the dental ceramic molded body. During the opening rotation, the holders maintain support for the material, transferring the movement force smoothly and preventing direct impact or dropping that would cause breakage.
3Ease of operation
If the cap is rotatable with holders forming continuous space, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The holder system is segmented into first holders in the container body and second holders in the cap. This segmentation allows each set of holders to perform specific functions - the first holders support material in the container while the second holders receive and support material in the cap during rotation, simplifying the overall design through functional division.

AI summary
A dental material container includes a cylindrical body that stores a dental material including a pair of opposing primary surfaces, and a rotatable cap covering the body. The cap includes an internal space capable of housing the dental material. The body includes a pair of first holders that are formed on an inner surface of the body to movably hold the primary surfaces of the dental material; the cap includes a pair of second holders formed inside of the cap to movably hold the primary surfaces of the dental material. When the cap is rotated in the circumferential direction relative to the body, a continuous space where the dental material is movable is formed by the first and second holders, the dental material located closest to the opening in the body moves into the cap, and the dental material moved into the cap is housed in the cap.
