Vehicle Assembly Alignment with Integrated Centering Features
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle body construction methods require complex and expensive positioning devices to align components with strict tolerances, limiting the efficiency and flexibility of the production process, especially for large modules that cannot be hot joined or fully sealed.
Innovation Solution
A method involving subassemblies aligned using positioning aids like centering pins and slots, followed by a materially bonded and force-fitting connection, allowing for simplified alignment and early handling stability without waiting for adhesive curing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If complex positioning devices are used to align components with strict tolerances, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent integrates positioning aids directly into the component structure itself, merging the positioning function with the structural component. This eliminates the need for separate, complex positioning devices while maintaining alignment precision through built-in features like positioning elements and receptacles.
Solution Approach 2:
The component serves its own positioning function through integrated positioning aids that are part of the component structure. The component automatically aligns with other components through these built-in features, eliminating the need for external positioning devices and reducing overall system complexity.
2Manufacturing precision
If adhesive bonding is used for large modules, then manufacturing precision is maintained, but production time increases due to curing requirements
Solution Approach 1:
The patent employs force-fitting connections that provide immediate mechanical stability and precise alignment before adhesive bonding is applied. This preliminary mechanical connection ensures proper positioning is established early, allowing the adhesive to cure in place without requiring extended positioning time or restricting production flow.
Solution Approach 2:
The patent transitions from relying solely on adhesive bonding (which requires curing time) to a combined approach using force-fitting connections that provide immediate structural stability. This changes the physical state of the connection from purely chemical (adhesive) to mechanical+chemical, enabling earlier handling and repositioning.
3Strength
If force-fitting connections are used with large connecting elements, then strength is improved, but weight increases
Solution Approach 1:
The patent distributes multiple connecting elements across different locations of the assembly rather than using fewer large connecting elements. Each connecting element is locally optimized for its specific position, providing sufficient strength where needed while minimizing overall material usage and weight.
Solution Approach 2:
The patent divides the connection system into multiple smaller connecting elements distributed throughout the assembly structure. This segmentation replaces fewer large, heavy connectors with multiple smaller, strategically placed connectors that collectively provide equal or superior strength while reducing total weight.
4Strength
If multiple connecting elements are used, then connection strength is improved, but device complexity increases
Solution Approach 1:
The patent employs connecting elements that serve multiple functions simultaneously: they provide mechanical strength through force-fitting connections, enable precise positioning through integrated positioning aids, and allow for standardized assembly procedures. This multi-functionality reduces the need for separate specialized components, simplifying the overall system despite using multiple connectors.
