Universal Bag Holder Structure for Reusable and Plastic Bags
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bag holders are not adaptable for reusable bags of various sizes and materials, as they are designed primarily for conventional plastic bags, leading to a need for specific holders that can accommodate different bag types.
Innovation Solution
A universal bag holder system with a rigid upstanding holder back, handle retainer structure, and elongated bag engagement members that can support both conventional and reusable bags by maintaining them in an open and stable upright position, allowing for adjustable positioning to fit different bag sizes and configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional bag holder structure is used, then it can hold T-shirt plastic bags effectively, but it cannot accommodate reusable bags of various sizes and materials
Solution Approach 1:
The patent applies universality by designing a single bag holder structure that can accommodate multiple types of bags (T-shirt plastic bags, reusable bags of various sizes and materials) through a standardized holder back with adjustable components, eliminating the need for separate holders for different bag types
Solution Approach 2:
The patent applies dynamics through adjustable components including vertically adjustable bag support members and reconfigurable handle retainers that can be positioned at different heights and configurations to adapt to various bag sizes and types, transforming a static structure into a dynamically adaptable system
2Adaptability or versatility
If specific holders are designed for reusable bags, then they can accommodate different bag sizes, but they cannot hold conventional plastic bags
Solution Approach 1:
The patent resolves this contradiction by creating a universal holder back design that integrates both T-shirt bag support features (rod members for aperture engagement) and reusable bag support features (adjustable support members and handle retainers), allowing a single device to perform multiple functions for different bag types
3Adaptability or versatility
If adjustable components are added to accommodate various bag sizes, then versatility improves, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the holder into modular components including the holder back, multiple adjustable support members, and separate handle retainer structures that can be independently positioned and configured, allowing versatility without requiring complex integrated adjustment mechanisms
