Animal Transport Backpack with Inverted Loading and Localized Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional animal backpacks fail to securely fix the animal's body, leading to uncomfortable and unsafe positions, causing weight shifts and potential falls for both the animal and the carrier, and are difficult to put on due to defensive reactions from the animal.
Innovation Solution
A backpack design featuring a chest harness with adjustable shoulder straps, a zipper system to separate the back and sack parts, recesses for the tail and hind legs, and width-adjustable Velcro fasteners to securely fix animals of different sizes in a comfortable position without constriction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the animal's body is allowed to move freely in the backpack, then the animal can maintain its natural position, but the weight distribution becomes unstable causing discomfort and potential falls
Solution Approach 1:
The patent applies local quality by providing targeted support only where needed - a support cushion positioned specifically at the animal's hindquarters and torso area, while leaving other areas free. This localized support stabilizes the animal's body position and prevents excessive movement that would cause weight shifts, without constraining the animal's natural posture or comfort in other regions.
2Reliability
If the animal is lifted into the backpack by the tail, then the animal can be secured inside, but the animal exhibits defensive reactions making the process difficult
Solution Approach 1:
The patent applies inversion by completely reversing the traditional loading approach. Instead of lifting the animal upward by the tail into a top-opening backpack, the design allows the animal to step forward into the backpack through a front opening and then be guided downward onto the support cushion. This inverted loading sequence eliminates the defensive reaction to tail handling and makes the process much easier and more natural for the animal.
Solution Approach 2:
The support cushion acts as an intermediary element that facilitates the loading process. By providing a soft, comfortable surface at the bottom of the backpack, it mediates between the animal and the confinement of the backpack, reducing stress and making the animal more cooperative during the loading process while ensuring secure positioning once inside.
3Device complexity
If the backpack uses a fixed design, then the structure is simple, but it cannot accommodate animals of different sizes comfortably
Solution Approach 1:
The patent applies dynamics by incorporating adjustable elements into the backpack structure. The shoulder straps include adjustable length mechanisms that allow the backpack to adapt to different animal sizes and carrying positions. This dynamic adjustability enables the same backpack structure to accommodate various animal sizes comfortably without requiring multiple different backpack models, thus maintaining structural simplicity while achieving versatility.

AI summary
A backpack for carrying an animal consists of an L-shaped rigid dorsal part (2), in the seat base of which a central hole-type cutout (5) is located, said seat base projecting at a right angle from the dorsal part. A pouch-type front part (1) having two hole-type cutouts (6, 6a) and a bib (4) is attached to the outer edges of the seat base (3). The dorsal part (2) and the pouch-type front part (1) are joined to one another by zippers. The bib (4) is connected, by means of clip-on closure pieces (11, 11a), to the clip-on closure pieces (13, 13a) on the fastening straps (9, 9a) that are guided through a plurality of loops (7, 7a) along the long lateral portions of the rigid dorsal part (2) and to the clip-on closure pieces (12, 12a) on the pouch-type front part (1). Trapezoidal outer pockets (14, 14a) are attached on both sides of the lower end of the rigid dorsal part (2), and a deflection buckle (16, 16a) for guiding the hook-and-loop fastener (17, 17a) therethrough is located at the end of each of said outer pockets (14, 14a).
