Trailer Drive Locking Mechanism for Maneuverable Waste Removal
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 and large trucks, which can damage landscapes and are difficult to maneuver in tight spaces, especially when disposing of roofing materials or other building remodeling debris.
Innovation Solution
A self-propelled tandem axle trailer with a rear storage bin and movable front axle, equipped with a locking mechanism and hydraulic drive assembly, allowing it to extend and position the storage bin near workers and support heavy loads, enabling efficient disposal of construction waste without damaging surrounding areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a large transport truck is used to remove construction waste, then the waste removal capacity is improved, but the landscape and surrounding areas are damaged
Solution Approach 1:
The system divides the waste removal function into two separate components: a small trailer that causes minimal landscape damage and a separate disposal location. The trailer is segmented from the disposal site, allowing waste to be collected and transported without requiring large trucks in sensitive areas.
Solution Approach 2:
The small trailer acts as an intermediary between the construction site and the disposal location. It serves as a mediator that collects waste at the site and transports it to a disposal area, eliminating the need for large trucks to operate in landscaped areas while maintaining efficient waste removal capability.
2Quantity of substance
If a large transport truck is used to remove construction waste, then the waste removal capacity is improved, but the maneuverability in tight spaces deteriorates
Solution Approach 1:
The waste removal system is segmented into a compact, maneuverable trailer for tight spaces and a separate disposal location. This segmentation allows the collection component to be small and agile while the disposal component can be located elsewhere, resolving the contradiction between size and maneuverability.
Solution Approach 2:
The small trailer serves as an intermediary vehicle that can easily navigate tight construction spaces. It collects waste and transports it to a disposal area, providing the maneuverability of a small vehicle while ultimately achieving the waste removal capacity of a larger system through the separate disposal location.
3Device complexity
If manual labor is used to lift and position building materials, then the equipment complexity is reduced, but the time consumption increases
Solution Approach 1:
The trailer is designed with self-service capabilities including its own drive system, steering, and positioning mechanisms. This allows the trailer to autonomously navigate to the disposal location and position itself, eliminating the need for complex lifting equipment while maintaining efficiency through self-powered operation.
4Productivity
If the storage bin is positioned near workers, then the waste disposal efficiency is improved, but the stability of the trailer deteriorates
Solution Approach 1:
The trailer employs dynamic stabilization through its drive system and positioning mechanisms. The powered wheels and active control systems allow the trailer to maintain stability even when the storage bin is extended forward near workers, converting what would be a static instability into a controllable dynamic state.
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 trailer allows for efficient and safe disposal of construction waste by enabling the trailer to position itself and support heavy loads, reducing manual labor and minimizing damage to landscapes, thus improving the efficiency and convenience of waste removal processes.
Implementation Method 1
The introduction of fluid through the first port may create a fluid pressure that causes the pushing member to move from the first position to the second position
Implementation Method 2
the urging member being normally biased in a first direction, and moved in a second direction by the pushing member

AI summary
A trailer for towing by a power vehicle is provided and generally includes a frame and a tandem wheel assembly. The trailer is provided with a drive assembly having a locking mechanism to selectively engage the drive from the motor to the wheels of the trailer. The locking mechanism having a reciprocating pushing member that may push an urging member to act upon a flanged driveshaft to selectively engage a clutch of the drive assembly.
