A multi-layer nested inner container design featuring a soft cup, hard inner long cylinder, and outer cylinder with stoppers and through holes, allowing for interference and snap fits, facilitating easy assembly and disassembly, and incorporating a control component for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a soft cup is wrapped with a hard plastic shell and fixed with pins or fasteners, then structural stability is improved, but disassembly convenience deteriorates
Solution Approach 1:
The inner container is divided into multiple separable components: the soft cup, the hard inner long cylinder, and the outer cylinder. These components can be easily separated through the through holes without requiring pin or fastener removal, thus maintaining structural stability during use while enabling convenient disassembly for cleaning.
Solution Approach 2:
The hard inner long cylinder acts as an intermediary component between the soft cup and the outer cylinder. It provides structural support and stability while allowing the soft cup to be easily inserted and removed through the through holes, resolving the contradiction between stability and disassembly convenience.
2Adaptability or versatility
If a soft cup is made entirely soft for elasticity and wrapping property, then wrapping performance is improved, but ease of holding and air-drying deteriorates
Solution Approach 1:
The inner container combines soft materials (soft cup made of TPE/TPR/silicone) with hard materials (hard inner long cylinder and outer cylinder made of hard plastic). This composite structure provides both the elasticity and wrapping property of soft materials and the rigidity and ease of handling of hard materials.
Solution Approach 2:
The soft cup is nested within the hard inner long cylinder, which is in turn nested within the outer cylinder. This nested structure allows the soft cup to maintain its wrapping properties while the hard outer layers provide structural support and ease of handling.
3Strength
If a soft cup is fit into a hard plastic shell, then structural support is improved, but gaps may be generated due to excessive resistance
Solution Approach 1:
The fitting interface is segmented into multiple regions: the soft cup fits into the hard inner long cylinder, which is separated from the outer cylinder by a gap. This segmentation reduces excessive resistance and prevents gaps from forming, while still providing adequate structural support.
Solution Approach 2:
The interference fit is applied locally at specific positions rather than uniformly throughout the entire interface. The stoppers are positioned at specific locations on the hard inner long cylinder to provide localized support, reducing overall resistance and preventing gap formation while maintaining necessary structural support.

Function Achieved in This Case
The design enables stable, efficient assembly and cleaning of the sperm extractor, improving user experience and functionality with snap fit assembly and snap fit mode, enhancing structural stability and ease of use.
Implementation Method 1
The driving component controls the soft cup to expand and contract, rotate and vibrate, to generate a stimulation effect
Implementation Method 2
at least part of an outer surface of the hard inner long cylinder is provided with stoppers, and the stoppers abut against the outer cylinder to form interference fit

AI summary
The utility model discloses a multi-layer nested inner container easy to disassemble and clean and a sperm extractor comprising the same. A soft cup is arranged in a cavity of a hard inner long cylinder in an interference fit manner to form a detachable assembly; the soft cup can be well fixed by means of the hard inner long cylinder, and the soft material of the soft cup makes the interference fit structure easy to assemble and stable; and an outer surface of the hard inner long cylinder is provided with stoppers, and the stoppers abut against an outer cylinder to form interference fit. In this way, when the soft cup is pulled out, the hard inner long cylinder can be used as an acting point, which facilitates assembly and cleaning. In addition, the snap fit assembly mode is simple, so assembly efficiency is improved.
