Power Rail-Support Unit for Guide-Track Transportation Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide-track transportation systems face challenges in maintaining high construction accuracy and reducing construction man-hours due to the need for individual positional adjustments of guide rails and insulator-attached plates, which can lead to deviations in relative positional relationships and increased construction time and costs.
Innovation Solution
A power rail-support unit with a base portion, guide rail, first and second fixing portions, a bracket, and a power rail that slides on a collector, allowing simultaneous determination and adjustment of the guide rail and power rail positions to maintain accurate relative positioning, reducing the need for separate adjustments and incorporating a bracket with a cable support and insulating features to minimize man-hours and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual installation and position adjustment of guide rail and insulator-attached plate are performed separately, then flexibility in installation is improved, but construction accuracy and construction time deteriorate
Solution Approach 1:
The patent combines the guide rail and insulator-attached plate into a single integrated assembly that is installed as one unit. The insulator-attached plate is pre-positioned relative to the guide rail, eliminating the need for separate installation and adjustment operations. This merging of components ensures that the relative positional relationship between the guide rail and power rail is maintained with high accuracy while simplifying the installation process.
Solution Approach 2:
The insulator-attached plate is pre-positioned and fixed relative to the guide rail before the entire assembly is installed on the track. This preliminary positioning ensures that the correct relative spatial relationship is established in advance, avoiding the need for complex on-site adjustments and ensuring construction accuracy from the outset.
2Ease of operation
If individual position adjustment of guide rail or insulator-attached plate is performed, then installation flexibility is improved, but construction man-hours and cost increase
Solution Approach 1:
By merging the guide rail and insulator-attached plate into a single pre-assembled unit, the patent eliminates multiple separate adjustment operations. The integrated assembly requires only one installation operation, significantly reducing construction man-hours and improving productivity while maintaining the necessary installation flexibility.
3Ease of operation
If separate fixing of guide rail and power rail is performed, then installation flexibility is improved, but relative positional relationship stability deteriorates
Solution Approach 1:
The patent merges the fixing operations by using a single fixing mechanism that secures both the guide rail and insulator-attached plate simultaneously. This ensures that their relative positional relationship remains stable and predetermined, while still allowing for flexible installation at different locations along the track.

AI summary
A power rail-support unit includes: a base portion that is integrally fixed on a track; a guide rail on which a guide wheel of a side portion of a vehicle travelling on the track abuts; a first fixing portion that is configured to fix the guide rail on the base portion; a second fixing portion that is connected to the guide rail so as to be independent of the first fixing portion; a bracket that is supported on the guide rail; and a power rail that is supported by the bracket so as to be arranged at a predetermined relative position relative to the guide rail, and that slides on and makes contact with a collector of the vehicle.
