Telescopic Bottom Frame for Compact Folding Pet Cages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable pet carriers occupy a large space even when folded and have a significant packaging size, making them inconvenient for transportation and storage.
Innovation Solution
A pet carrier design featuring a carrier frame with a bottom rod assembly that allows for relative movement of bottom rods, enabling the frame to fold into a compact state by accommodating one rod within another, and utilizing a connecting mechanism with an elastic piece to secure the folded position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the pet carrier uses a traditional foldable structure with rigid bottom frame, then the carrier can be folded, but the folded size remains large and occupies significant storage space
Solution Approach 1:
The bottom rod assembly employs a telescopic structure where one bottom rod is inserted into another bottom rod during folding, enabling nested configuration. This nesting mechanism allows the bottom frame to collapse to minimal dimensions while maintaining structural integrity, directly reducing the folded volume of the pet carrier.
Solution Approach 2:
The bottom rod assembly transitions from a static rigid structure to a dynamic telescopic structure that can adapt between extended and retracted states. This dynamic capability allows the carrier to achieve compact folding while maintaining ease of operation through simple extension and retraction movements.
2Volume of moving object
If the pet carrier uses a foldable structure with telescopic bottom rods, then the folded size is reduced, but the structure becomes more complex
Solution Approach 1:
The telescopic bottom rod assembly uses a nested configuration where rods are inserted into each other, eliminating the need for complex folding mechanisms. This nesting approach reduces structural complexity while achieving compact folding, as the rods simply slide in and out of each other along their longitudinal axes.
Solution Approach 2:
The bottom frame is segmented into multiple telescopic rod units that can independently extend and retract. This segmentation allows each rod to be simplified in design while collectively achieving the complex function of variable-size bottom frame, reducing overall structural complexity through modular design.
3Ease of manufacture
If the bottom frame uses a fixed rigid structure, then the manufacturing is simple, but the packaging size and transportation space are large
Solution Approach 1:
The bottom frame transitions from a fixed rigid structure to a dynamic telescopic structure with movable rods. While this increases manufacturing complexity slightly, it dramatically reduces packaging size and transportation space, as the frame can be collapsed to minimal dimensions for storage and shipping.
Solution Approach 2:
The telescopic bottom rods are designed to nest within each other, creating a compact configuration for packaging. This nesting design minimizes the volume required for packaging and transportation while maintaining simple manufacturing processes for each individual rod component.

AI summary
A pet cage, comprising a cage frame having an unfolded state. In the unfolded state, the cage frame comprises: a left side support frame and a right side support frame which are arranged at an interval in the left-right direction; an upper connecting frame, wherein when the pet cage is in the unfolded state, the upper part of the left side support frame and the upper part of the right side support frame are respectively connected to the upper connecting frame; and a bottom frame, wherein the lower part of the left side support frame and the lower part of the right side support frame are rotatably connected to the bottom frame, the bottom frame comprises a bottom rod assembly extending between the left side support frame and the right side support frame, and the bottom rod assembly comprises a plurality of bottom rods which can move relative to one another in the length direction. The pet cage has a small size after being folded, and is convenient to package, transport and store.
