Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If screws are used to connect the connecting member and carousel, then the assembly is easy to manufacture, but the connection becomes unstable and unsafe after prolonged use due to loosening
Solution Approach 1:
The patent merges the connecting member and carousel into an integrated structure where the connecting member is formed as one piece with the carousel, eliminating the need for separate screws and fasteners. This integration ensures that the connection between these components is permanent and cannot loosen over time, while still being manufacturable through single-piece molding or fabrication processes.
Solution Approach 2:
The patent removes the screw fastening mechanism from the connection system between the connecting member and carousel. By extracting the screw element entirely and replacing it with an integrated design, the patent eliminates the source of loosening and instability while simplifying the overall structure.
2Strength
If additional screws and fasteners are used to secure the connecting member, then the connection strength is improved, but the device complexity increases and safety is reduced due to more potential failure points
Solution Approach 1:
The patent combines multiple separate components (connecting member, carousel, and fastening elements) into a single integrated structure. This merging maintains connection strength through the unified design while reducing structural complexity by eliminating multiple parts and assembly steps.
Solution Approach 2:
The integrated connecting member-carousel structure performs multiple functions simultaneously: it provides structural support, enables rotation, and ensures secure connection without requiring separate fastening components. This multi-functionality reduces the overall number of parts while maintaining or improving connection strength.
3Ease of operation
If the carousel unit is connected horizontally to the base unit, then the rotation is simple, but the sensory stimulation is limited and less engaging for children
Solution Approach 1:
The patent introduces dynamic movement patterns by connecting the carousel unit at an angle to the base unit, enabling the carousel to rotate both horizontally and vertically during operation. This dynamic connection allows the carousel to tilt and rotate in multiple directions, providing varied sensory stimulation while maintaining operational simplicity through a single rotation mechanism.
Solution Approach 2:
The patent adds a vertical dimension to the rotation by angling the connecting member relative to the base unit. Instead of purely horizontal rotation, the angled connection enables the carousel to move through three-dimensional space, creating both horizontal circular motion and vertical tilting motion that enriches the sensory experience for children.
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 design provides a stable and reliable connection, enhances safety by preventing loose parts, and offers a more engaging sensory experience with horizontal and vertical rotation sensations, improving the overall safety and enjoyment of the training process.
Implementation Method 1
The rotation shaft is embedded in the connecting channel and connected to the base unit. The carousel unit is rotatably disposed along an axial direction of the rotation shaft via the rotation shaft relative to the base unit.
