Transport Deck Frame Separate Pivot Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deck frame configurations for trucks and trailers either lack adaptability for medium-sized trailer configurations or fail to seamlessly integrate both tilt and dump functions, particularly when used with truck decks or dual axle trailers.
Innovation Solution
A transport deck assembly with two separate pivot connections, one for tilting and another for dumping, allowing the deck frame to pivot about distinct axes, enabling both tilt and dump functions while being adaptable to single or dual axle, truck, or trailer frames, and incorporating a lift mechanism and mode selection member for operational flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single pivot axis is used for both tilt and dump functions, then the device complexity is reduced, but the adaptability for different vehicle configurations (truck decks, dual axle trailers, medium-sized trailers) deteriorates
Solution Approach 1:
The invention divides the pivot connection system into two separate, independently selectable pivot connections: a first pivot connection for tilt operations and a second pivot connection for dump operations. This segmentation allows each pivot connection to be optimized for its specific function and positioned at appropriate locations for different vehicle configurations, thereby resolving the contradiction between device complexity and adaptability.
Solution Approach 2:
The invention implements a dynamic selection mechanism that allows the system to switch between different pivot connection configurations based on the operational mode (tilt or dump) and vehicle type. The ability to selectively engage different pivot connections provides dynamic adaptability without permanently increasing structural complexity.
2Ease of operation
If the pivot axis is positioned well ahead of the rear end for tilt configuration, then the ease of loading wheeled vehicles is improved, but the ability to lift the deck to a near vertical orientation for dumping deteriorates
Solution Approach 1:
The invention introduces a mode selection mechanism that acts as an intermediary between the two pivot connection systems. This selector allows the operator to choose which pivot connection is active based on the desired operation, enabling the system to provide either optimal tilt positioning for vehicle loading or optimal dump positioning for vertical deck orientation, depending on the selected mode.
3Adaptability or versatility
If sliding components are incorporated to adjust pivot axis location, then the adaptability for different configurations is improved, but the ease of operation and suitability for medium-sized trailers deteriorates
Solution Approach 1:
The invention extracts the complexity of adjustable pivot positioning by removing the need for sliding components entirely. Instead, the system provides fixed but separately selectable pivot connections for tilt and dump operations. This extraction of the adjustment function resolves the contradiction by maintaining adaptability through selection rather than continuous adjustment, thereby preserving ease of operation.

AI summary
A deck for a truck or trailer has a base frame and a deck frame movable relative to the base frame to either one of a tilt position or a dump position. A first pivot connection between the frames defines the pivot axis of the tilt position while a second pivot connection separate and spaced from the first pivot connection defines the pivot axis of the dump position. A common lift mechanism between the frames lifts the deck frame to either one of the tilt or dump positions depending upon the operative condition of the first and second pivot connections.
