Modular Smoking Disposal Unit with Elevated Receptacle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposal units for smoking products are costly, difficult to maintain, and pose fire hazards due to their design and placement at ground level, which complicates emptying and reassembly, and are not weather-resistant.
Innovation Solution
A disposal unit with a tubular extension divided into sections, featuring a closed-bottom receptacle with removable caps and elevated placement to facilitate easy emptying and maintenance, fabricated from standard metal tubes for low-cost production and sleek design, with a snuffing surface to extinguish smoldering products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ash trays are placed at ground level for accessibility, then ease of operation is improved, but maintenance difficulty increases and fire hazards worsen
Solution Approach 1:
The disposal unit is divided into separate modular components including a base unit and one or more receptacles that can be detached and removed independently. This segmentation allows the receptacle to be easily separated from the base for maintenance, cleaning, or replacement without moving the entire unit, thus improving ease of repair while maintaining accessibility.
2Ease of operation
If receptacles are made detachable for easy emptying, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The receptacle is designed as a detachable component that can be separated from the base unit through simple mechanical interfaces. This segmentation enables easy removal and emptying of the receptacle while maintaining a relatively simple overall device structure, balancing ease of operation with acceptable device complexity.
3Ease of operation
If ash trays are exposed to outdoors for public access, then accessibility is improved, but reliability worsens due to weather damage
Solution Approach 1:
The receptacle incorporates a bonnet or cover that shields the collection chamber from direct exposure to rain and weather elements. This protective enclosure maintains public accessibility while preventing water accumulation and weather-related damage, thereby improving reliability without sacrificing accessibility.
4Object-affected harmful factors
If collection chamber is molded with complex shape to form hooded cranny, then fire safety is improved, but manufacturing cost increases
Solution Approach 1:
The fire safety features are implemented through modular components such as a separate bonnet and standardized collection chamber rather than a single complex molded piece. This segmentation allows for simpler, more cost-effective manufacturing of individual parts while maintaining the protective hooded structure that prevents fire hazards.
5Quantity of substance
If disposal unit has wide area receptacle for capacity, then quantity of substance is improved, but device complexity increases for packaging
Solution Approach 1:
The disposal unit is designed with modular components including a base and detachable receptacles that can be packaged separately or in simple configurations. This segmentation allows for adequate receptacle capacity while simplifying packaging requirements, as the modular parts can be efficiently arranged and shipped without complex packaging structures.

AI summary
A disposal unit for discarded smoking products has, a lower tubular section mounted on a base, an upper tubular section with an interior partition to form a closed-bottom receptacle for the discarded smoking products, a removable cap covering an open end of the upper tubular section, and the cap and tubular sections are detachable from one another for emptying the receptacle.
