Solution Overview
Problem
Paper bags are inconvenient to use due to ease of tearing, difficulty in opening fully, vulnerability to puncture, and limitations in capacity utilization, and existing solutions like hard tanks are bulky, unstable, and inefficient for dustpan use.
Innovation Solution
A foldable paper bag recycling storage plate with a guide plate and paper bag support plate structure, hinged with pin and pin cover, allowing for compact storage and easy conversion into a slot shape for stable garbage housing, enabling vertical or horizontal use and easy garbage collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a hard tank is used to support the paper bag, then the paper bag can be supported and its capacity can be utilized, but the hard tank occupies space when unused and is inconvenient to store
Solution Approach 1:
The guide plate is designed to be rotatable relative to the support plate, transitioning between a compact flat configuration for storage and an extended L-shaped configuration for supporting the paper bag. This dynamic transformation allows the same structure to serve dual purposes: minimizing storage volume while providing stable support when needed.
Solution Approach 2:
The support structure is divided into two functional segments: the support plate that interfaces with the paper bag and the guide plate that directs items. These segments are connected by a hinge, allowing independent movement and transformation of each part to optimize both storage efficiency and functional performance.
2Ease of operation
If the guide plate notch is made larger to facilitate item insertion, then items can be easily placed, but the guide plate becomes easily broken
Solution Approach 1:
The guide plate is segmented into multiple parts by fold lines, creating a modular structure that can flex and deform without breaking. When items are placed, the guide plate segments can bend to accommodate the notch opening, reducing stress concentration and preventing fracture while still allowing easy item insertion.
Solution Approach 2:
The guide plate transitions between different structural states through rotation and folding. In the extended state, it provides a rigid guide for item placement; during item insertion, it can flex locally at the notch while maintaining overall structural integrity through its foldable design.
3Stability of the object's composition
If the guide plate is made irreversible for stability, then the structure is stable, but it is inconvenient to store when unused
Solution Approach 1:
The guide plate is designed with rotational freedom around a hinge axis, allowing it to dynamically adjust between a stable extended position for guiding items and a compact folded position for storage. This dynamic capability eliminates the need for irreversible construction while maintaining structural stability during use.
Solution Approach 2:
The structure is divided into separable components (support plate and guide plate) connected by a hinge, enabling independent movement and transformation of each segment. This segmentation allows the guide plate to be rotated and folded without compromising the overall structural integrity during use.
4Adaptability or versatility
If the paper bag is placed horizontally for dustpan use, then it can serve as a dustpan, but the guide plate cannot rotate for folded paper
Solution Approach 1:
The guide plate is hinged to the support plate, allowing it to rotate and adapt to different paper bag configurations. Whether the paper bag is upright or folded horizontally, the guide plate can rotate to maintain its guiding function, enabling versatile use as both a storage container and a dustpan.
Solution Approach 2:
The hinged guide plate design provides universal functionality across different paper bag states. It can guide items whether the bag is in its original upright position or folded horizontally for dustpan use, making the system adaptable to multiple functions without requiring separate components.

AI summary
The invention relates to an environment-friendly paper bag recycling storage plate characterized by comprising a guide plate structure and a paper bag support plate structure which are folded by a hard foldable material. The guide plate structure is hinged with an end of the paper bag support plate structure, when in storage, the guide plate structure and the paper bag support plate structure are closely abutted and folded into a flat plate, when in use, the paper bag support plate structure and the guide plate structure are folded into a slot shape, the paper bag support plate structure is inserted into a paper bag, and a garbage housing space is formed by the slot-shaped paper bag support plate structure and the paper bag, after the guide plate structure is turned in place towards the direction away from the paper bag support plate structure, garbage enters the garbage housing space along the guide plate structure. When the environment-friendly paper bag recycling storage plate is horizontally placed to serve as a dustpan, scraps can be swept into the paper bag by a broom. The environment-friendly paper bag recycling storage plate is reusable, compact in whole structure, convenient to use, lighter than a common garbage bin, convenient to carry, foldable when not in use, small in occupied space, low in manufacturing cost, and easy to use by common people.
