Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicles in manufacturing environments face challenges in efficiently supporting and maneuvering large or heavy components, particularly in assembly processes, due to limitations in lifting and maneuvering capabilities, especially when multiple vehicles are required to handle such loads.
Innovation Solution
A vehicle design incorporating a frame, drivetrain, base assembly, and a lifting implement with a cradle, scissor assembly, and multi-stage telescoping actuator, allowing for selective raising and lowering of the cradle, along with adjustable bracket assemblies for accommodating different-sized components, and prop wings for maintaining raised positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing vehicles are used to support and maneuver large or heavy components, then the vehicle structure remains simple, but the lifting and maneuvering capabilities are insufficient and multiple vehicles are required
Solution Approach 1:
The lifting implement is divided into distinct functional modules: a base assembly coupled to the vehicle frame, a scissor assembly with multiple linkages for mechanical advantage, a multi-stage telescoping actuator for controlled extension, and a cradle for component support. This segmentation allows each module to be optimized independently while collectively providing enhanced lifting capability.
Solution Approach 2:
The multi-stage telescoping actuator employs a nested structure where multiple actuator stages are contained within each other, allowing compact storage when retracted and extended length when deployed. This nesting principle enables the actuator to provide substantial stroke length without excessive retracted volume, resolving the contradiction between lifting capability and structural compactness.
2Force
If multiple vehicles are used to handle heavy loads, then the lifting capability is sufficient, but the operational efficiency decreases and coordination becomes complex
Solution Approach 1:
The patent combines the lifting function, maneuvering capability, and positioning systems into a single integrated vehicle platform. The base assembly serves as the foundation for both vehicle operations and lifting operations, while the scissor assembly and actuator work together to provide controlled lifting. This merging eliminates the need for multiple separate vehicles and improves operational efficiency.
3Length of stationary object
If a single-stage actuator is used for lifting, then the structure is simple, but the lifting height and control precision are limited
Solution Approach 1:
The multi-stage telescoping actuator uses nested stages where inner actuators are contained within outer actuators. This allows the system to achieve greater total extension length by sequentially extending each stage, while maintaining a compact retracted profile. The nested structure resolves the contradiction between achieving high lifting height and maintaining actuator compactness.
Solution Approach 2:
The actuator system employs dynamic control where multiple stages can be extended and retracted independently or in sequence, allowing adaptive adjustment of lifting height and speed. This dynamic capability enables precise positioning at various heights while maintaining structural efficiency, resolving the contradiction between lifting height and control precision.
