Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotatable paste containers face issues with paste suddenly moving up or down due to incorrect user operation, leading to inconvenience and potential waste, and they often require additional elastic members like springs that are not environmentally friendly.
Innovation Solution
A rotatable paste container design that eliminates the need for additional elastic members by using a sliding projection on the screw sleeve member to engage with a sliding track and pit, controlling the rotation angle with a predetermined angle, and utilizing a plastic structure for all parts to facilitate recycling and reduce environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metal spring is used to control rotation angle, then resilience is improved, but recyclability deteriorates
Solution Approach 1:
The patent replaces the metal spring with a plastic spring that is part of an integrated moldable structure. This plastic component is cheaper, easier to recycle, and can be molded directly into the housing as a single piece, eliminating the need for separate spring installation while maintaining the necessary elastic function for rotation angle control.
Solution Approach 2:
The patent merges the spring function directly into the housing structure through integral molding. The housing is molded as a single piece with the spring already formed inside it, eliminating the need for separate spring components and assembly steps. This integration improves recyclability while maintaining the elastic function needed for rotation control.
2Ease of manufacture
If a plastic spring is used to control rotation angle, then recyclability is improved, but resilience deteriorates
Solution Approach 1:
The patent uses a plastic spring that is molded integrally with the housing rather than being a separate component. This approach maintains recyclability through plastic material while achieving sufficient resilience through proper mold design and material selection, eliminating the need for metal springs while maintaining functional performance.
Solution Approach 2:
The patent changes the material parameters of the spring by using specifically engineered plastic materials with appropriate elastic properties. By selecting plastics with suitable tensile strength, elasticity, and recovery characteristics, the design achieves the necessary resilience for rotation angle control while maintaining recyclability and eliminating metal spring requirements.
3Reliability
If the rotating body moves vertically to control rotation angle, then rotation control is improved, but device complexity deteriorates
Solution Approach 1:
The patent merges the rotation control mechanism directly into the housing structure through integral molding. The housing is molded as a single piece with the spring and rotation control features already formed inside it, eliminating the need for separate components and complex assembly mechanisms. This integration simplifies the overall structure while maintaining reliable rotation angle control.
Solution Approach 2:
The patent extracts the rotation control function from complex mechanical linkages and embeds it directly into the housing structure through molded features. The spring and rotation control mechanisms are formed as integral parts of the housing, removing the need for separate control mechanisms and reducing structural complexity while maintaining functional performance.

AI summary
A rotatable paste container is provided in the disclosure, which includes a paste box, a screw assembly and a rotating assembly. A first protrusion is formed at an outer side of a bottom of the paste box, and a sliding track is provided on the first protrusion, and a pit is provided on the sliding track. The rotating assembly includes a screw sleeve member and a rotating body. The screw sleeve member includes at least one support arm, and a sliding projection which is repeatedly engaged with the sliding track and the pit respectively is provided at a top of the at least one support arm, so that when the rotating assembly rotates relative to the paste box, the sliding projection is repeatedly engaged with the pit along the sliding track, thereby constantly controlling a rotation angle of the rotating body with a predetermined angle.
