Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current trolleys for slidable cantilever gates are complex, costly to produce, and lack mechanical strength due to numerous components requiring laborious welding and finishing steps, leading to potential malfunctions and noise issues during gate operation.
Innovation Solution
A trolley design using two shaped metal plates with orthogonal folds to form a load-bearing structure, reduced to fewer components, and assembled using rivets or screws for quicker production, with adjustable support wheels and guide wheels to ensure precise alignment and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional multi-component support structures are used with welding operations, then assembly flexibility is improved, but production time and cost increase significantly
Solution Approach 1:
The patent merges multiple separate components (base plate, vertical plates, reinforcing elements) into a single monolithic support structure formed from one or more continuously extruded profile sections. This eliminates the need for welding operations and component assembly, directly resolving the contradiction by maintaining structural flexibility while dramatically increasing production speed through continuous manufacturing processes.
Solution Approach 2:
The extruded profile sections are designed to perform multiple functions simultaneously: providing structural support, defining mounting positions for wheels and rollers, incorporating reinforcement features, and enabling adjustment mechanisms. This multi-functionality eliminates the need for separate components, resolving the contradiction by reducing assembly operations while maintaining manufacturing flexibility.
2Adaptability or versatility
If multiple plates are assembled by welding to form support structure, then structural adaptability is improved, but mechanical strength decreases
Solution Approach 1:
The patent combines multiple plated components into a single monolithic extruded structure that cannot be separated. This eliminates weak weld joints while maintaining structural adaptability through integrated design features such as built-in mounting positions, adjustment mechanisms, and reinforcement elements that are inherently part of the continuous structure.
Solution Approach 2:
The patent employs composite cross-sectional designs within the extruded profiles, combining different material properties and structural configurations in a single continuous piece. This creates a structurally superior support system that maintains adaptability while achieving higher mechanical strength through optimized material distribution and elimination of joint weaknesses.
3Ease of operation
If complex finishing steps including thread machining are performed, then functional capability is improved, but production cycle time increases
Solution Approach 1:
The patent incorporates threading features, mounting positions, and adjustment mechanisms directly into the extrusion process itself. Threads and structural features are formed during the continuous extrusion operation before the material cools and hardens, eliminating the need for subsequent machining operations while maintaining full functional capability for wheel mounting, adjustment, and assembly.
Solution Approach 2:
The extruded profiles are designed to provide multiple functions in a single manufacturing step: structural support, wheel mounting features, adjustment mechanisms, and reinforcement. This multi-functionality achieved through integrated extrusion eliminates the need for separate finishing operations, resolving the contradiction by maintaining operational functionality while dramatically reducing production cycle time.
4Adaptability or versatility
If numerous components are assembled together, then adjustment capability is improved, but manufacturing precision decreases
Solution Approach 1:
The patent combines multiple adjustable components into a single monolithic extruded structure with integrated adjustment features. The precision of wheel alignment and positioning is determined by the extrusion process itself rather than by cumulative assembly tolerances of multiple separate parts, thereby maintaining full adjustment capability while achieving superior manufacturing precision through reduced tolerance stacking.

AI summary
Trolley for a slidable cantilever gate comprising two L-shaped plates, each provided with a load-bearing wall and a base wall which is extended without interruption from the load-bearing wall by means of a substantially orthogonal fold. The load-bearing walls are rigidly connected by means of screws or rivets with the two base walls oriented in opposite directions so as to form a support base on ground. Each load-bearing wall is provided with two first through openings aligned with respective corresponding first openings of the other load-bearing wall so to jointly define two first seats adapted to house first rotatable support means for two pairs of support wheels; and with a second through opening aligned with that corresponding on the other load-bearing wall so to jointly define a second seat for receiving a guide wheel, rotatably supported by second rotatably support means. The load-bearing walls, moreover, are each provided with a first shape with concavity facing that of the other load-bearing wall in order to jointly define a first housing adapted to receive a fixing screw of the pin of the guide wheel, and a second shape with concavity facing that of the other load-bearing wall in order to jointly define a second housing, which communicates with a vertical guide defined in one of the first seats, and houses adjustment means operating on a slide which bears, pivoted, a pair of adjustable wheels, in order to adjust its vertical height.
