Universal Bag Holder Structure for Reusable Bag Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bag holders are not compatible with reusable bags of various sizes and materials, as they are designed primarily for conventional plastic bags, leading to a need for specialized holders that can accommodate different bag types.
Innovation Solution
A universal bag holder apparatus 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 and compatibility with existing bag holders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional bag holder structures are used, then they can effectively hold plastic bags, but they cannot accommodate reusable bags of various sizes and materials
Solution Approach 1:
The bag holder is designed with a universal structure that can accommodate both plastic bags and reusable bags of various sizes. The holder back with handle retainer structure and elongated bag engagement members creates a system that adapts to different bag types without requiring separate specialized holders, thus achieving multi-functionality while maintaining relatively simple device structure.
Solution Approach 2:
The bag holder employs movable and adjustable components including the handle that can be positioned at different locations and the elongated bag engagement members that can accommodate various bag sizes. This dynamic adjustability allows the same holder structure to adapt to different bag types and dimensions without increasing inherent structural complexity.
2Adaptability or versatility
If specialized bag holders for reusable bags are designed, then they can accommodate various reusable bag sizes, but they increase device complexity
Solution Approach 1:
The bag holder is divided into functional segments: the holder back, the handle with handle portion, and the elongated bag engagement members. This segmentation allows each component to be optimized for its specific function while maintaining overall simplicity. The handle can be independently positioned and the engagement members can independently adapt to different bag sizes.
Solution Approach 2:
The design incorporates dynamic elements such as the movable handle that can be positioned at different locations on the holder back and the flexible elongated bag engagement members that can adapt to various bag sizes. This dynamic capability provides versatility for different reusable bag dimensions without requiring multiple specialized holders or overly complex fixed structures.
3Adaptability or versatility
If a universal bag holder design is implemented, then compatibility with both plastic and reusable bags is achieved, but the handle mechanism becomes more complex
Solution Approach 1:
The handle mechanism is designed to serve multiple functions: it can engage with the holder back at different positions, work with both plastic bags having apertured handles and reusable bags without such features, and provide stable support. This multi-functionality is achieved through a relatively simple mechanism consisting of the handle portion, elongated bag engagement members, and retainer structure, avoiding unnecessary complexity while achieving universal compatibility.
