Pre-loaded Waste Bag System with Drawstring Securing Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waste bag systems are time-consuming and prone to messiness, with prior art systems either failing to securely engage nested bags with the waste bin or causing bags to slide inside due to weight, and lacking convenient closure mechanisms.
Innovation Solution
A pre-loaded waste bag system with drawstrings that engage with securing members on the waste bin, maintaining bags in place and featuring scent strips that release a fragrance when an inner bag is removed, ensuring secure attachment and easy access for disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If nested waste bags are placed in a waste bin without a securing system, then the bags can be easily installed, but the weight of the nested bags causes them to slide into the interior of the waste bin
Solution Approach 1:
The patent applies preliminary action by pre-attaching the drawstrings to the securing members before the bags are fully installed. The drawstrings are extended through the hems and tied to the securing members in advance, so that when the nested bags are placed in the waste bin, they are automatically held in position by the pre-configured drawstring-tension system, preventing slippage while maintaining easy installation
Solution Approach 2:
The patent uses drawstrings as an intermediary element between the nested waste bags and the securing members. The drawstrings transmit the holding force from the securing members to the bag hems, enabling reliable position stabilization without requiring direct attachment mechanisms that would complicate installation
2Ease of operation
If perforated bags are used in a nested system, then bags can be separated by tearing, but the system is prone to bag ripping and lacks a convenient closure mechanism
Solution Approach 1:
The patent extracts the closure function from the bag material itself (no perforations or tearing needed) and implements it through the drawstring system. The drawstrings can be untied to close or remove the bag opening, providing a reliable closure mechanism that maintains bag integrity while still allowing easy separation and removal of individual bags from the nested system
Solution Approach 2:
The patent applies dynamics by making the drawstring tension adjustable and reversible. The drawstrings can be tightened to secure the bag, loosened to close it, or completely removed to detach the bag from the nested system. This dynamic system provides both secure holding and easy separation without compromising bag integrity through perforations
3Reliability
If individual waste bags are detached from a roll and positioned in a waste bin, then each bag can be properly installed, but the process is time-consuming and potentially messy if a bag failure occurs
Solution Approach 1:
The patent applies the nesting principle by placing multiple waste bags inside each other in a nested configuration within the waste bin. This allows multiple bags to be pre-positioned and secured simultaneously as a single unit, dramatically increasing installation speed and productivity. The nested structure maintains reliability because each bag is individually secured with its own drawstring to the securing members, so if one bag fails, the others remain intact and properly installed

AI summary
One or more embodiments provide a pre-loaded waste bag system comprised of a plurality of disposable, drawstring waste bags nested one inside the other. The waste bin is comprised of a rigid frame containing two pairs of securing members molded into or affixed to opposite sides of the outside of the waste bin walls. The waste bags are placed inside the waste bin, with the drawstrings looped around the securing members located on the waste bin. The innermost bag is removed by sliding the drawstring of the innermost bag off of the securing members and pulling the innermost bag out of the waste bin. The action separates two sheets of a releasable, scented square releasing a pleasant odor or perfume contained within the two sheets.
