Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The mail order business faces challenges in efficiently packaging diverse and differently sized goods, leading to excessive waste due to the need for multiple types of disposable packaging, which are not used optimally after delivery.
Innovation Solution
A reusable mailing bag with adjustable volume, featuring closure and compression mechanisms that allow it to accommodate various sizes of goods securely, made from flexible material without a cover, and equipped with a shipping window and carrying straps for multiple uses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple types of disposable packaging are used to accommodate different goods sizes, then adequate shipping and transport safety is ensured, but waste increases and raw materials are not used optimally
Solution Approach 1:
The bag incorporates adjustable closure means that allow dynamic adjustment of the bag volume between a first volume and a second volume. This dynamic adaptability enables a single reusable bag to accommodate different goods sizes while maintaining secure closure, eliminating the need for multiple disposable packaging types and reducing waste.
Solution Approach 2:
The reusable bag is designed to perform multiple functions by accommodating various goods sizes through its adjustable volume mechanism. A single bag design replaces multiple specialized packaging types, achieving both adequate shipping safety and material efficiency through its universal adaptability.
2Adaptability or versatility
If a reusable mailing bag is designed to accommodate various goods sizes, then packaging versatility improves, but the bag structure becomes more complex
Solution Approach 1:
The closure mechanism is segmented into multiple independent closure means (first closure means and second closure means) positioned at different locations on the bag. Each closure means can independently adjust to define different bag volumes, allowing versatile adaptation without requiring a single complex mechanism. The segmentation enables simpler, modular adjustment while achieving multiple volume states.

AI summary
The description pertains to a bag for shipping goods in the mail order business with a front side, a back side, a left side, a right side, a bottom side and a bag opening with an opening edge for the insertion and removal of the goods. This bag should be further developed in such a way that, on the one hand, it can accommodate a variety of different and differently sized goods in a manner that is safe for shipping and transport and on the other hand that it can be used as a reusable mailing bag in order to avoid unnecessary waste. To solve this problem, it is proposed to arrange back-side closure means at a back distance from the opening edge and to arrange first closure means on the front side at a first front-side distance from the opening edge and second front-side closure means at a second front-side distance from the opening edge, wherein the first front-side distance is smaller than the second front-side distance and the back-side distance is smaller than the first front-side distance, so that the bag opening becomes closable by turning over an upper region of the back side to the front side and connecting the back-side closure means to the first front-side closure means to provide a larger bag volume or to the second front closure means to provide a smaller bag volume.
