EV Chassis Platform Connector Guides for Precise Module Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing chassis platform modules for electric vehicles lack a standardized assembly position for connectors, leading to inconsistent adhesion performance and increased assembly variations, which results in additional manufacturing costs and reduced durability, strength, and rigidity.
Innovation Solution
Incorporating guide protrusions on the frame and support parts to ensure the connector members are assembled at predetermined positions, using a combination of adhesive and coupling members like bolts, to standardize the assembly process and maintain consistent adhesion performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a position fixing jig is separately manufactured to fix the connector position, then the assembly position can be standardized, but an additional manufacturing process is added causing increased cost
Solution Approach 1:
The patent integrates the position fixing function directly into the connector structure by providing guide protrusions on the connector body that fit into guide grooves on the support part. This merging of the positioning function into the connector itself eliminates the need for separate position fixing jigs, thereby standardizing assembly positions without adding manufacturing complexity or cost.
Solution Approach 2:
The connector is designed with self-positioning capabilities through its guide protrusions that automatically align with the guide grooves on the support part during assembly. This self-service positioning mechanism eliminates the need for external fixing devices or additional positioning processes, allowing operators to assemble connectors at consistent positions without requiring separate positioning tools.
2Device complexity
If no separate component is provided for connector placement, then the structure is simpler, but the connector assembly position varies depending on the operator
Solution Approach 1:
The patent introduces guide protrusions on the connector and corresponding guide grooves on the support part as intermediary positioning elements. These intermediary features mediate between the connector and support part, providing a standardized interface that ensures consistent assembly positions without requiring complex additional structures or components.
