Self-Propelled Trailer With Extendable Bin For Construction Waste
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for removing construction waste from building sites are inefficient, as they often require manual labor, damage landscaped areas, and pose challenges in positioning disposal containers near the work site, especially when large trucks cannot access the location.
Innovation Solution
A self-propelled trailer with a rear extending storage bin, equipped with a drive system, stabilizers, and an extension device, allowing it to move independently and position the storage bin for easy loading and unloading of materials, while minimizing damage to surrounding areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a large truck is used to transport and dispose of construction waste, then the disposal capacity is improved, but the damage to landscaped areas (fences, lawns, shrubs) worsens
Solution Approach 1:
The system divides the disposal function into two separate components: a large truck for waste collection at a distance, and a small portable dispenser for final disposal near the building. This segmentation allows the large truck to avoid damaging landscaped areas while maintaining high disposal capacity, as the small dispenser can be easily positioned on lawns or near shrubs without causing significant damage.
2Productivity
If a large truck is positioned adjacent to the building for waste disposal, then the disposal efficiency is improved, but the ability to access the location worsens due to landscaping obstacles
Solution Approach 1:
The disposal system is segmented into a large truck that can remain on accessible roads and a small portable dispenser that can be positioned in hard-to-reach areas near the building. This allows the system to maintain high disposal efficiency while adapting to locations that large trucks cannot directly access.
Solution Approach 2:
The small portable dispenser acts as an intermediary between the large truck and the final disposal location. It receives waste from the truck and transfers it to the building, enabling disposal in areas that would otherwise be inaccessible to large vehicles.
3Device complexity
If manual labor is used to move building materials and debris, then the equipment complexity is reduced, but the time consumption and labor intensity worsen
Solution Approach 1:
The system employs a self-propelled trailer that autonomously transports building materials from the truck to the building without requiring manual handling. The trailer moves itself under its own power, significantly reducing the time and labor required while maintaining relatively simple equipment complexity compared to full mechanized systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The self-propelled trailer efficiently positions the storage bin near the work site, reducing manual labor and damage to landscaped areas, enabling easier disposal of construction waste without the need for large trucks to access the site.
Implementation Method 1
a first extension section with a trailing end rotatably connected to the frame and an extendable second extension section rotatably connected to a leading end of the first extension section
Implementation Method 2
a pair of stabilizers positioned along opposite sides of the frame, each stabilizer having an outer end configured to extend downwardly toward a ground when the trailer is on the ground
