Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the highchair is designed as a foldable structure, then the ease of storage and portability is improved, but the height adjustability is lost
Solution Approach 1:
The highchair is divided into multiple independent segments including front and rear support frames, adjustable sleeve members, detachable armrest connecting rods, and separable components. This segmentation allows each part to be adjusted or folded independently, enabling height adjustment while maintaining foldability for storage.
Solution Approach 2:
The patent implements dynamic adjustability through height-adjustable sleeve members with insertion holes, detachable armrest connecting rods, and position-adjustable dining trays. These dynamic elements allow the highchair to adapt to different heights and configurations, resolving the contradiction between fixed foldable structure and height adjustability.
2Adaptability or versatility
If the highchair structure is made complex to achieve height adjustability, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent employs nesting by placing insertion holes within sleeve members, and positioning the dining tray within the space between armrests. The armrest connecting rods are nested within the overall support frame structure. This nesting approach allows multiple adjustment functions without proportionally increasing external complexity.
Solution Approach 2:
The support frames serve multiple functions: providing structural support, enabling folding for storage, and supporting height-adjustable components. The armrest connecting rods simultaneously provide structural support and enable height adjustment when detached. This multi-functionality reduces the need for separate dedicated components for each function.

AI summary
A multifunctional foldable highchair includes a front support frame and a rear support frame. The front support frame and the rear support frame are arranged in a foldable manner, and the front support frame and the rear support frame are both in a “U” shape. Two vertical parts of the front support frame are respectively provided with a left sleeve member and a right sleeve member. The left sleeve member and the right sleeve member are height-adjustable. Inner side surfaces of the left sleeve member and the right sleeve member are respectively provided with a detachable left armrest connecting rod and a detachable right armrest connecting rod. Top front ends of the left armrest connecting rod and the right armrest connecting rod are respectively provided with a left armrest and a right armrest. A dining tray is provided between the left armrest and the right armrest.
