Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for assembling vehicle body components require large factory spaces and incur high facility and personnel costs due to the need for different machinery for various vehicle types, making them inefficient and costly to adapt to changing vehicle designs.
Innovation Solution
A system featuring a rotatable index table with interchangeable assembly units, jigs, and welders that can handle various vehicle types by rotating through multiple assembly sections, allowing for manual or robotic operation and reducing the need for extensive facility modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different carriages and assembly systems are used for each vehicle type, then assembly precision and reliability are maintained, but facility investment costs and factory space requirements increase significantly
Solution Approach 1:
The patent implements a universal carriage system with interchangeable tooling jigs that can accommodate multiple vehicle types (SUV, sedan, truck) on a single assembly line. The carriage structure includes standardized mounting points and adjustable positioning mechanisms that allow different tooling sets to be quickly swapped, enabling one carriage to perform the function of multiple specialized carriages while maintaining assembly precision for each vehicle type
Solution Approach 2:
The system employs dynamically adjustable tooling jigs with movable components that can be repositioned and reconfigured for different vehicle models. The tooling includes adjustable clamping mechanisms, movable positioning blocks, and reconfigurable fixture assemblies that adapt to varying vehicle dimensions and assembly requirements, allowing the same physical carriage to maintain reliability across different vehicle types through dynamic reconfiguration rather than requiring static dedicated carriages for each model
2Manufacturing precision
If multiple specialized assembly lines are established for different vehicle types, then manufacturing precision is maintained, but initial investment costs and personnel expenses increase
Solution Approach 1:
The assembly system is segmented into modular functional units including independent tooling jig modules, interchangeable fixture sets, and separable positioning systems that can be independently selected and configured for different vehicle types. This segmentation allows the facility to maintain high assembly precision by using specialized modular components for each vehicle type while avoiding the need to build entirely separate dedicated assembly lines, thereby reducing overall facility investment costs
Solution Approach 2:
The tooling and fixture systems incorporate adjustable parameters including variable positioning coordinates, reconfigurable clamping forces, and adaptable fixture geometries that can be modified through mechanical adjustment mechanisms. These parameter changes allow the same physical assembly infrastructure to maintain manufacturing precision across different vehicle types by simply adjusting key parameters rather than requiring completely different specialized facilities for each model
3Ease of manufacture
If a single multi-functional assembly system is used for various vehicle types, then facility investment costs are reduced, but the complexity of adapting to different vehicle configurations increases
Solution Approach 1:
The system incorporates pre-configured tooling jig sets and standardized fixture assemblies that are prepared in advance for different vehicle types. These pre-prepared tooling packages include pre-arranged positioning elements, pre-set clamping mechanisms, and preorganized component layouts that can be quickly installed on the carriage without requiring complex on-site configuration, thereby reducing system configuration complexity while maintaining cost-effectiveness
