Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clips, buckles, Velcro, or magnetic members are used to attach the mesh to the carriage, then the animal can be confined inside the carriage, but the user needs to spend time fastening and these components are prone to breaking after constant use
Solution Approach 1:
The mesh is integrated with the canopy body to form a unified structure, eliminating the need for separate attachment components like clips, buckles, Velcro, or magnetic members. This merging of functions resolves the contradiction by providing both reliable confinement and time-saving operation through a single integrated canopy assembly that covers and secures the carriage opening simultaneously.
2Reliability
If the canopy is closed to prevent the animal from getting out, then the animal is confined safely, but the temperature inside the carriage becomes very high during summer
Solution Approach 1:
The canopy body incorporates localized mesh panels in specific regions while maintaining solid fabric in other areas. This local quality differentiation allows the canopy to provide both confinement (through the closed structure) and ventilation (through the mesh panels), resolving the contradiction between safety and temperature control by providing targeted airflow in hot weather while maintaining overall enclosure security.
3Adaptability or versatility
If a large size pet stroller is used to accommodate both small and large animals, then versatility is improved, but the stroller becomes bulky and difficult to maneuver in narrow spaces
Solution Approach 1:
The supporting frame assembly incorporates adjustable components that allow the carriage body dimensions to be modified. The adjustable supporting frame can be reconfigured to change the carriage length and width, enabling the stroller to adapt to different pet sizes while maintaining a compact form factor when adjusted for smaller pets, thus resolving the contradiction between versatility and maneuverability.
4Ease of manufacture
If additional supplemental tools are used to detach and attach the rear wheels, then the rear wheel assembly can be assembled, but the user needs to spend a lot of time and the components are easy to break
Solution Approach 1:
The rear wheel assembly is integrated with the supporting frame assembly through direct structural connection, eliminating the need for separate supplemental tools for attachment and detachment. The wheels are mounted as part of the frame structure itself, allowing users to easily service the wheels without requiring additional tools, thus resolving the contradiction between assembly feasibility and operational ease.

AI summary
A pet stroller includes a canopy fabric, a supporting frame, a first longitudinal frame, a second longitudinal frame, a rear wheel frame, and a plurality of wheels. The supporting frame includes a carriage body which has an accommodating cavity and a front opening. The supporting frame includes a main supporting frame, an adjustable supporting frame and a utility frame extended from the main supporting frame to a position corresponding to the front opening of the carriage body for allowing pet's access. When the adjustable supporting frame is in a lying position, the adjustable supporting frame is pivotally moved to substantially align with the main supporting frame for maximizing a volume of the accommodating cavity. When the adjustable supporting frame is in the first inclined position, it is pivotally moved to inclinedly and upwardly extended from the main supporting frame for reducing a size of the accommodating cavity.
