Universal Loading Jig for Trunk Lid and Tail Gate Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing loading jig systems for trunk lids and tail gates are inflexible and require separate, costly modifications or new manufacturing for different vehicle types, limiting efficient assembly line production due to the need for vehicle-specific positioning and alignment units.
Innovation Solution
A loading jig apparatus with movable units and adjustable support structures, including guiders and roller attachments, that can align and position both inner and outer parts of trunk lids and tail gates across various vehicle types using a common framework, allowing for flexible manufacturing by adjusting to different sizes and shapes through motor-driven movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate loading jigs are used for trunk lid and tail gate, then positioning and alignment precision is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the loading jig functions for both trunk lid and tail gate into a single integrated apparatus. The jig includes a common base structure with adjustable support units that can accommodate both panel types, eliminating the need for separate dedicated jigs while maintaining positioning precision through adjustable mechanisms.
Solution Approach 2:
The loading jig is designed as a universal apparatus that can handle both trunk lid and tail gate panels through adjustable support units. The jig includes configurable positioning mechanisms that adapt to different panel geometries, allowing one device to perform multiple functions that previously required separate specialized equipment.
2Manufacturing precision
If vehicle-specific restriction units are used, then positioning accuracy for each vehicle type is improved, but adaptability to different vehicle types deteriorates
Solution Approach 1:
The loading jig incorporates dynamically adjustable support units that can be reconfigured for different vehicle types. The adjustment mechanisms allow the jig to adapt its geometry and positioning points dynamically, maintaining high positioning accuracy across various vehicle models without requiring vehicle-specific fixed units.
Solution Approach 2:
The jig employs adjustable parameters including support unit positions, heights, and angles that can be modified to match different vehicle specifications. This parametric adjustability enables the same jig structure to achieve precise positioning for multiple vehicle types by changing configuration parameters rather than requiring different hardware.
3Manufacturing precision
If multiple dedicated jigs are manufactured, then assembly quality is improved, but additional investment costs increase
Solution Approach 1:
The patent merges multiple dedicated jig functions into a single apparatus, reducing the total number of jigs that need to be manufactured and maintained. This consolidation lowers manufacturing costs while preserving assembly quality through the use of adjustable positioning mechanisms that replicate the precision of dedicated jigs.
Solution Approach 2:
By creating a universal loading jig that can handle both trunk lid and tail gate assemblies, the system eliminates the need to manufacture separate dedicated jigs for each panel type. This multi-functional approach reduces capital investment while maintaining high assembly quality through configurable support and positioning units.
