Solution Overview
Problem
Conventional waste disposal devices are inefficient in utilizing space, particularly in rooms with limited space, as they do not accommodate non-right angle corners and do not maximize storage capacity within a compact configuration.
Innovation Solution
A compact waste disposal system with a waste disposal device and cassette featuring unique geometries such as triangular, Reuleaux triangle, conic, or frusto-conic sections, allowing for efficient use of space and accommodating non-right angle corners, along with a film-dispensing mechanism that forms a bag-like structure for waste storage.

Engineering Contradiction Analysis
1Volume of moving object
If conventional rectangular waste disposal devices are used, then manufacturing and placement are simple, but space utilization is inefficient and non-right angle corners cannot be accommodated
Solution Approach 1:
The waste disposal device employs asymmetric geometric configurations including triangular, Reuleaux triangle, conic, and frusto-conic cross-sections. These asymmetric shapes enable the device to accommodate non-right angle corners and maximize space utilization in irregular spaces, directly resolving the contradiction between storage capacity and geometric simplicity.
2Volume of moving object
If the device is made compact to save floor space, then floor space utilization improves, but waste storage capacity may be reduced
Solution Approach 1:
The invention transitions from conventional rectangular prismatic shapes to three-dimensional geometric forms such as cones and frusto-conics. These shapes optimize the volume-to-footprint ratio by utilizing vertical and radial dimensions more efficiently, allowing compact floor space occupation while maintaining or increasing waste storage capacity.
Solution Approach 2:
The device incorporates curved geometric forms including conic and frusto-conic sections with rounded profiles. These curved shapes maximize volume within a compact footprint by eliminating wasted corner spaces and optimizing spatial distribution, thereby increasing storage capacity without proportionally increasing floor space occupation.
3Volume of moving object
If the included angle between side walls is optimized for compactness, then space utilization improves, but structural stability may be compromised
Solution Approach 1:
The device employs specific included angle ranges (60-120 degrees) between side walls to optimize the balance between compactness and structural stability. This parameter optimization ensures that the geometric configuration maximizes space utilization while maintaining adequate structural integrity through mathematically determined optimal angles.
