Garbage Can Retaining Clip With Pinch Gate and Ridges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing retaining clips for securing garbage bags are inefficient in keeping excess bag material tightly secured around garbage cans, lacking effective mechanisms to maintain the bag in place without manual effort.
Innovation Solution
A retaining clip with a housing and a flexible bag gate that moves between pinch and lifted positions, combined with parallel retaining ridges and a hinged tab, securely holds the garbage bag in place by pinching the excess material and allowing easy release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a simple retaining clip structure is used, then the device complexity is reduced, but the effectiveness in securing garbage bag excess is insufficient
Solution Approach 1:
The retaining clip is divided into multiple functional components: a body portion with retaining ridges for securing the bag, a gate portion for pinching excess material, and a tab portion for operation. This segmentation allows each component to perform its specific function effectively while maintaining overall structural coherence.
Solution Approach 2:
The gate portion and tab portion are nested within or integrated with the body portion of the retaining clip. The gate can be positioned within the housing, and the tab is coupled to the body, creating a compact nested structure that reduces overall complexity while maintaining functionality.
2Ease of operation
If manual effort is required to hold the bag in place, then the securing mechanism is simpler, but the ease of operation is reduced
Solution Approach 1:
The gate is designed to be movable between different positions (open and closed) to dynamically adjust the pinching action on the bag excess. The tab can be moved to different positions to engage or disengage the retaining ridges, providing dynamic control over the securing mechanism without requiring continuous manual effort.
Solution Approach 2:
The retaining ridges and gate work together to automatically secure the bag excess when the tab is engaged, reducing the need for continuous manual intervention. Once the tab is positioned to engage the retaining ridges, the mechanism maintains the secured state without requiring ongoing user input.
3Stability of the object's composition
If the bag excess is not tightly secured, then the device structure is simpler, but the stability of the bag position is reduced
Solution Approach 1:
The retaining ridges are specifically positioned and shaped to provide localized gripping points on the bag excess, creating high-friction contact zones that prevent slippage. The gate is designed to concentrate pinching force at a specific location on the bag excess, ensuring tight local securing that translates to overall bag stability.

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 clip effectively secures the garbage bag tightly around the can, ensuring the excess material is kept in place without manual effort, while allowing for easy disengagement when needed.
Implementation Method 1
A bag gate (32) is flexibly coupled to the left side (22) within the housing inside (26). The bag gate (32) moves between a pinch position (34) extending substantially perpendicularly from the left side (22) to adjacent the right side (24)... The bag gate (32) is biased to rest in the pinch position (34)
Implementation Method 2
The bag gate (32) is biased to rest in the pinch position (34)

AI summary
A garbage bag retaining clip apparatus for securing garbage bag excess includes a housing having an open front side separated from an open back side, a top side separated from an open bottom side, and a left side separated from a right side defining a housing inside. A bag gate is flexibly coupled within the housing inside. The bag gate is biased to rest in the pinch position. A plurality of parallel retaining ridges is coupled to the housing. Each of the retaining ridges extends vertically from the right side and the left side within the housing inside. A tab is coupled to the housing. The tab proximal end has a hinge extending between the left side and the right side proximal the top side and the back side. The tab moves between a locked position engaged within the retaining ridges and a released position extending behind the housing.
