Foldable Pet Carrier Bag with Expandable Back Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet carrier bags have limited expansion and contraction spaces due to fabric restrictions, and lack bottom support, making them inconvenient for pets.
Innovation Solution
A foldable and expandable pet carrier bag design featuring a zipper-connected backside with a pad body, support rings, mesh fabric sides, a hard bottom plate, and a breathable cushion, allowing for a cuboid structure expansion with a pet pad and easy folding mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a zipper is added on the side of the bag body to expand the bag, then the pet's activity space is increased, but the expansion space is extremely limited due to fabric restrictions and the bottom has no support
Solution Approach 1:
The bag is divided into a fixed bottom wall and an expandable side wall section. The bottom wall remains stationary while the side walls can be extended using the zipper mechanism, allowing expansion without compromising the structural integrity and support provided by the fixed bottom.
Solution Approach 2:
A fabric panel with zipper connections serves as an intermediary element that bridges the fixed bottom wall and the expandable side walls. This panel allows the side walls to extend outward while maintaining connection to the stable bottom structure, enabling supported expansion.
2Weight of moving object
If the bag is made small for easy portability, then portability is improved, but the pet's activity space is reduced
Solution Approach 1:
The bag transitions from a static small size to a dynamic configuration where the side walls can be extended. The zipper mechanism allows the bag to adapt its volume based on the pet's needs, providing a compact form for portability and an expanded form for comfort.
Solution Approach 2:
The expandable side walls are designed to nest within or alongside the fixed bottom structure when not in use. The bag maintains a compact collapsed state for portability, with the expansion sections stored in a space-efficient manner that minimizes the overall footprint.
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 spacious, supportive, and versatile pet carrier bag with enhanced expansion volume, improved pet comfort, and convenient folding, addressing the limitations of existing bags.
Implementation Method 1
the outlines between the support rings are formed by a connection of the elastic soft fabric or the mesh-like fabric
Implementation Method 2
a breathable back cushion adapted to fit on the back of the human body

AI summary
The foldable and expandable pet carrier bag includes a pet carrier bag body (10). The pet carrier bag body is provided with a first pet door (11), and the pet carrier bag body has a back part (12) which is provided with a foldable expanding part. The expanding part includes a top wall (21), a bottom wall (22), a left side wall (23), a right side wall (24) and a front side wall (25). The left side wall and the right side wall are folded toward the inner portion of the expanding part, respectively. The bottom wall and the front side wall that overlapped on the surface of the bottom wall are swung and overlapped on the top wall. The pet carrier bag is easy to fold. After being folded, the bottom wall of the expanding part fixed on the pet carrier bag body forms a back cushion.
