Conveyance Apparatus Cable Routing Simplification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conveyance apparatuses face challenges in facilitating the wiring of cables for movable holding units, leading to complex and inefficient manufacturing processes.
Innovation Solution
A conveyance apparatus featuring a base unit, a link mechanism support unit, a holding unit, and a cable system where the cable is fixed to the holding unit and link mechanism support unit, allowing the cable to bend and advance with the holding unit, simplifying cable wiring by eliminating the need for complex routing through pivotable connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cable is routed through pivotable connections in the link mechanism, then the holding unit can be advanced and retreated, but the cable wiring becomes complex and manufacturing efficiency decreases
Solution Approach 1:
The patent extracts the cable routing from the complex pivotable connection system and creates a separate, simplified cable guide mechanism. The cable guide unit is positioned independently on the link mechanism support unit, allowing the cable to be routed externally along the advancing/retreating path rather than through the pivot joints, thereby simplifying wiring while maintaining full movement functionality
Solution Approach 2:
The cable guide unit acts as an intermediary element between the link mechanism support unit and the holding unit. It provides a dedicated pathway for the cable to follow during the advancing and retreating movements, mediating the cable's interaction with the moving components without requiring complex routing through pivot connections
2Reliability
If complex cable routing through pivotable connections is used, then reliable cable connection is achieved, but manufacturing process becomes inefficient
Solution Approach 1:
The cable routing system is segmented into distinct functional elements: the cable guide unit fixed to the link mechanism support unit, and the cable attachment point on the holding unit. This segmentation allows each component to be manufactured and assembled independently, simplifying the manufacturing process while ensuring reliable cable connection through dedicated connection points
3Adaptability or versatility
If the cable extends in the retreating direction and bends back in the advancing direction, then the cable accommodates the holding unit movement, but the cable path becomes longer
Solution Approach 1:
The cable routing is designed to be dynamic rather than static. The cable guide unit is positioned to allow the cable to naturally extend and bend back as the holding unit advances and retreats. This dynamic configuration enables the cable to adapt to the movement range without requiring excessive length, as the cable path changes optimally with each position of the holding unit

AI summary
A conveyance apparatus (carriage main part) includes a link mechanism that advances and retreats a holding unit horizontally with respect to a link mechanism support unit, and includes a pair of multi-joint arms that connects the link mechanism support unit and the holding unit. The cable is fixed to the link mechanism support unit by extending from a portion thereof fixed to the holding unit in a retreating direction of an advancing and retreating direction, and then, being bent back in an advancing direction, and as the holding unit advances, the bent-back position F of the cable also advances.
