Adjustable Part Transport Pallet for Multi-Type Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pallets require dedicated mechanisms for aligning and positioning specific types of parts, leading to increased equipment costs and reduced flexibility in handling multiple types of components in vehicle production factories.
Innovation Solution
A part transporting pallet with a lifter and multiple part aligning units, including positioning pins and support pads, that can adjust to accommodate different types of parts, allowing for correct positioning and transport by autonomous mobile robots, reducing the need for multiple pallets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If dedicated mechanisms for aligning and positioning specific types of parts are provided on pallets, then positioning precision for each part type is improved, but device complexity and equipment costs increase
Solution Approach 1:
The pallet is designed with multiple types of positioning pins (first, second, third positioning pins) that can be selectively used depending on the part type. This universal design allows a single pallet to accommodate and precisely position multiple different part types without requiring dedicated mechanisms for each part, thereby reducing device complexity while maintaining positioning precision.
Solution Approach 2:
The locator is configured to be movable relative to the pallet body, allowing dynamic adjustment of the positioning mechanism. This enables the same pallet to adapt to different part geometries and positioning requirements by adjusting the locator position, rather than requiring fixed dedicated mechanisms for each part type.
2Manufacturing precision
If dedicated mechanisms for aligning specific types of parts are formed on pallets, then positioning accuracy for each part type is improved, but adaptability to handle multiple part types deteriorates
Solution Approach 1:
The pallet incorporates multiple positioning pins and support pads that can be selectively engaged depending on the part type being handled. This universal design enables the same pallet to adapt to multiple different part types while maintaining accurate positioning through the appropriate positioning mechanism for each part.
Solution Approach 2:
The positioning system is segmented into multiple independent positioning pins (first, second, third positioning pins) and support pads that can be independently selected and adjusted based on the specific part type, allowing the pallet to adapt to different parts while maintaining positioning accuracy.
3Manufacturing precision
If multiple dedicated pallets are produced for different part types, then positioning precision for each part type is improved, but loss of substance and equipment investment costs increase
Solution Approach 1:
The pallet is designed as a universal carrier that can handle multiple part types using the same positioning pins and support pads. This eliminates the need to produce multiple dedicated pallets for different part types, reducing equipment investment costs and material consumption while maintaining positioning precision through selective use of positioning mechanisms.
Solution Approach 2:
Instead of discarding or replacing pallets for different part types, the system allows reuse of the same pallet by adjusting and selecting different positioning pins and support pads configurations, thereby recovering the value of the pallet and avoiding additional equipment investment.

AI summary
A part transporting pallet transports a part to a predetermined destination by a mobile carriage that includes a lifter which is configured for moving upwards and downwards in a vertical direction, and includes: a pallet body that forms at least one coupling hole which may be coupled with the lifter; and plurality of part aligning units have at least two position aligning pins that correctly position parts of different types on the pallet body, and are provided on the pallet body to vary the position of the position aligning pins according to the types of the parts.
