Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional infant swings use large standing frames and swing arms, then structural stability is improved, but portability and ease of assembly deteriorate
Solution Approach 1:
The infant chair is divided into separate modular components including a base unit and a seat unit that can be easily assembled and disassembled. The coupling mechanism allows the seat unit to be attached to or removed from the base unit without complex tools or procedures, resolving the contradiction between structural stability and ease of assembly.
Solution Approach 2:
The seat unit can be nested within or attached to the base unit in a compact configuration, allowing the entire apparatus to be easily stored or transported when not in use, while maintaining structural stability when assembled for use.
2Stability of the object's composition
If conventional infant swings use large standing frames, then structural stability is improved, but portability deteriorates
Solution Approach 1:
By segmenting the apparatus into a lightweight base unit and a separable seat unit, the overall weight is reduced and distribution is optimized for portability, while each component maintains sufficient structural stability when assembled.
Solution Approach 2:
The apparatus transitions from a static, heavy frame structure to a dynamic, reconfigurable system where components can be assembled or disassembled on demand, providing structural stability when needed and portability when required.
3Ease of operation
If conventional swings perform vertical pendulum motion, then soothing function is provided, but motion-induced sickness occurs
Solution Approach 1:
Instead of using the conventional vertical pendulum motion, the invention inverts the motion direction to horizontal oscillation. The seat unit oscillates back and forth in a horizontal plane, providing the soothing function while eliminating the vertical displacement that causes motion-induced sickness in children.
4Ease of operation
If conventional swings use complicated folding mechanisms, then portability is improved, but device complexity increases
Solution Approach 1:
The apparatus uses simple segmentation into modular units with straightforward coupling mechanisms, avoiding complicated folding structures. The seat unit attaches to or separates from the base unit through a simple coupling action, reducing device complexity while maintaining portability.
Solution Approach 2:
The system uses dynamic assembly and disassembly of modular components rather than static folding mechanisms, simplifying the overall device structure while enabling easy portability when needed.
