Centralized Power Source Carriage for Conveying Elevation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional carriage-type conveying apparatuses for automobile assembly lines require a motor on each conveying carriage for elevating the workpiece support base, leading to high costs and increased equipment complexity, as well as safety concerns due to the need for multiple power sources and potential misoperation risks.
Innovation Solution
A carriage-type conveying apparatus with an elevatable workpiece support base and elevating drive means, where the power source is centralized on a separate power source carriage positioned at workpiece support height changing positions, synchronously traveling with the conveying carriage and integrated mechanically for efficient height adjustments, reducing the number of power sources needed and enhancing safety through locking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a motor is installed on each conveying carriage for elevating the workpiece support base, then the workpiece support base can be elevated independently on each carriage, but the equipment cost increases and the number of power sources increases
Solution Approach 1:
The power source (motor) is extracted from each individual conveying carriage and relocated to a separate, dedicated elevating device positioned alongside the traveling path. This centralizes the power source while maintaining the elevation function, reducing the number of motors from one per carriage to one per elevation station.
Solution Approach 2:
A dedicated elevating device acts as an intermediary between the conveying carriages and the power source. This intermediary device receives the carriage, provides the elevation function through a single motor, and returns the carriage to the travel path, eliminating the need for motors on each carriage.
2Adaptability or versatility
If multiple power sources are distributed on each conveying carriage, then the elevation function is available everywhere, but the safety risk increases due to potential misoperation
Solution Approach 1:
The power source is extracted from the movable conveying carriage and placed in a fixed, dedicated elevating device. This centralization allows for better control and monitoring of the elevation operation, reducing safety risks associated with distributed power sources on multiple carriages.
Solution Approach 2:
The dedicated elevating device automatically detects when a carriage requires elevation and performs the elevation operation without manual intervention. The system self-regulates the elevation process, reducing the risk of misoperation by eliminating manual control of multiple distributed motors.
3Adaptability or versatility
If a motor is installed on each conveying carriage, then the elevation function is integrated with each carriage, but the cost of the conveying carriage and entire equipment increases
Solution Approach 1:
The motor is extracted from each costly conveying carriage unit and consolidated into a separate, shared elevating device. This reduces the cost per carriage while maintaining the elevation function, as the power source is now a shared resource rather than a component of each individual carriage.
Solution Approach 2:
The dedicated elevating device serves multiple conveying carriages sequentially, making the power source universal rather than specific to each carriage. This multi-functionality reduces the total number of motors needed and lowers overall equipment cost while maintaining elevation capability for all carriages.

AI summary
A carriage-type conveying apparatus with a workpiece support base and an elevating drive has a passive shaft interlocked with the elevating drive and a lock to prevent descent of the workpiece support base A power source carriage capable of traveling synchronously with the conveying carriage is aside of a traveling path of the conveying carriage at a workpiece support height changing position so as to be reciprocable along the traveling path. The power source carriage has a transmission shaft driven by a power source and a separable interlock to interlock the passive shaft and a transmission shaft with each other.
