Bag dispensing apparatus and bag dispensing system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bag dispensing systems occupy space, are difficult to manage, and require cumbersome actions for use, such as tearing and storing plastic bags, especially in limited spaces like vehicles.
Innovation Solution
A bag dispensing apparatus with a housing, bag retaining mechanism, and locking mechanism that allows a roll of bags to be stored and a leading bag to be hung for direct use, featuring a retraction mechanism to manage bag extension and a tearable mouth design for convenient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If bags are stored separately from the dispensing location, then storage is provided, but space is occupied and management becomes troublesome
Solution Approach 1:
The patent merges the storage function and dispensing function into a single integrated device. The bag roll is stored within the housing and can be directly dispensed from the same location, eliminating the need for separate storage areas and reducing overall space occupation.
Solution Approach 2:
The bag roll is nested within the housing structure, with the retaining mechanism allowing the roll to be stored compactly inside the device body. This nesting arrangement enables storage without requiring additional external space.
2Productivity
If multiple actions are required for bag use (tearing, opening, setting), then bags can be dispensed, but operation becomes troublesome and time-consuming
Solution Approach 1:
The bag roll is pre-positioned on the retaining mechanism with the leading bag already exposed and ready for use. The retaining mechanism is pre-configured to allow easy access and dispensing, eliminating the need for users to perform preparatory actions like searching for bags or setting them up.
Solution Approach 2:
The leading bag is extracted and exposed from the roll through the bag outlet, allowing users to directly access and use the bag without needing to tear or open it. The design extracts only the necessary portion (leading bag) while keeping the rest stored.
3Ease of operation
If the bag roll can rotate freely with the retaining mechanism, then dispensing is easy, but the roll cannot be locked for storage stability
Solution Approach 1:
The retaining mechanism incorporates a locking component that can dynamically switch between locked and unlocked states. When locked, the bag roll is fixed for stable storage; when unlocked, the roll can rotate freely for easy dispensing. This dynamic capability resolves the contradiction between stability and ease of operation.

AI summary
A bag dispensing apparatus and a bag dispensing system are disclosed. The bag dispensing apparatus includes a housing, a bag retaining mechanism, and a bag locking mechanism. A roll of bags is stored in the bag dispensing apparatus and a leading bag of the roll of bags can be directly hanged on the bag dispensing apparatus for use. The storage and use of the bags are cleverly integrated to save the space, and the operation is more convenient.
