Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pet waste bag dispensers suffer from limited storage capacity, cumbersome design, and inefficient management of bag rolls and empty cores, often requiring frequent refills and manual core removal.
Innovation Solution
A wall-mounted dispenser made of durable ABS plastic with internal ribs for roll support, stoppers to prevent forward movement, and apertures for easy core removal, along with a hinged lid and versatile mounting options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the dispenser is designed to hold multiple rolls of bags, then the storage capacity is improved, but the device complexity increases
Solution Approach 1:
The interior space is segmented into multiple compartments using partition walls, allowing the dispenser to hold multiple rolls of bags simultaneously. Each compartment can accommodate a separate roll, organized in a structured manner that prevents chaos while maintaining accessibility.
Solution Approach 2:
The dispenser utilizes vertical space by arranging rolls in multiple levels or tiers within the interior cavity. This dimensional organization allows multiple rolls to be stored without significantly increasing the horizontal footprint, effectively improving storage capacity while maintaining a compact overall form factor.
2Volume of moving object
If the dispenser is designed to be compact and wall-mounted, then the space efficiency is improved, but the ease of operation for core removal deteriorates
Solution Approach 1:
The core removal system includes dedicated extraction openings positioned on the front or side of the dispenser body. These openings allow users to easily access and remove empty cores from the interior without needing to open the entire dispenser or dig through multiple rolls, significantly improving ease of operation despite the compact design.
Solution Approach 2:
The dispenser design allows users to independently remove cores through the extraction openings without requiring assistance or complex disassembly. The core extraction mechanism is designed to be intuitively operable, enabling users to maintain the dispenser themselves with minimal effort.
3Ease of operation
If the dispenser includes features for easy core removal, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The core removal system incorporates dedicated extraction openings positioned on the front or side of the dispenser body. These openings allow users to easily access and remove empty cores from the interior without needing to open the entire dispenser or dig through multiple rolls, significantly improving ease of operation despite the compact design.
Solution Approach 2:
The extraction openings serve multiple functions: they allow core removal, provide ventilation for the interior space, and contribute to the overall aesthetic design of the dispenser. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity while still improving ease of operation.

AI summary
A wall-mounted pet waste bag dispenser comprising a hollow body defining an interior space and a dispensing opening. The body, formed of a lightweight and durable plastic material, includes a plurality of ribs disposed in a lower portion of the interior space to support multiple rolls of pet waste bags and prevent jamming during dispensing. A plurality of stoppers in an upper portion of the interior space prevent the rolls from falling forward out of the body. The dispenser incorporates a core removal system comprising a plurality of apertures disposed on an end of the body, allowing empty roll cores to be easily pushed out. The interior space accommodates up to four standard-size rolls, and the dispenser includes a hingedly attached lid, an oval-shaped aperture for easy bag dispensing, and a versatile mounting system.
