Interchangeable Docking Plates for Fast Vehicle Fixture Changeovers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing automated production systems for motor vehicles require frequent conversion of workstations to accommodate different vehicle types, leading to inefficiencies due to the need for modifying or replacing positioning and holding devices, which are specific to each vehicle geometry.
Innovation Solution
A method and device utilizing interchangeable docking plates with receptacles that can be easily swapped on a base frame, allowing the same basic frames and modules to be used for producing different vehicle types, with the docking plates being fixed using a zero-point clamping system and gripped by robots for precise positioning and exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If positioning and holding devices are modified or replaced for different vehicle types, then manufacturing precision is maintained, but device complexity and changeover time increase
Solution Approach 1:
The base frame is designed with a universal interface system that can accommodate multiple docking plates with different geometries. The zero-point clamping system provides a standardized mounting mechanism that works with various docking plate configurations, allowing the same base frame to serve multiple vehicle types without modification.
Solution Approach 2:
The positioning system is divided into modular components: a permanent base frame, interchangeable docking plates, and removable receptacles. This segmentation allows only the necessary receptacles to be changed for each vehicle type while retaining the expensive base frame infrastructure.
2Manufacturing precision
If positioning and holding devices are replaced for different vehicle types, then manufacturing precision is maintained, but loss of time during changeover increases
Solution Approach 1:
Different receptacle configurations are pre-mounted on separate docking plates before production changeover is needed. When a vehicle type change is required, the entire pre-configured docking plate is exchanged as a single unit rather than assembling individual receptacles during changeover.
Solution Approach 2:
The system transitions from static, permanently mounted receptacles to dynamic, interchangeable docking plates. This allows the receptacle configuration to adapt quickly to different vehicle types through simple plate exchange rather than complex reassembly operations.
3Manufacturing precision
If different base frames are used for different vehicle types, then manufacturing precision is maintained, but storage requirements and device complexity increase
Solution Approach 1:
A single base frame design serves as a universal platform for multiple vehicle types through the docking plate interface system. This eliminates the need to store and maintain multiple different base frame types, reducing both storage requirements and inventory complexity.
Solution Approach 2:
The system combines multiple receptacle configurations into a single base frame by mounting different docking plates with various receptacle arrangements on the same base frame structure, allowing one base frame to replace multiple specialized frames.
