Vehicle Door Sash Molding Integration for Attachment Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle door sash structure requires complex and time-consuming attachment processes for the molding and run channel, necessitating a large number of man-hours due to their separate component configuration.
Innovation Solution
Integration of the molding and run channel into a single molding assembly that can be attached to the window frame from the vehicle outer side to the inner side, simplifying the attachment process and reducing the required man-hours.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the molding and run channel are formed as separate components, then the sealing function is achieved, but the attachment work becomes complicated and requires a large number of man-hours
Solution Approach 1:
The patent combines the molding and run channel into a single integrated molding assembly. The run channel is formed as an integral part of the molding structure, eliminating the need for separate attachment operations. This merging of components maintains the sealing function while significantly reducing attachment complexity and man-hour requirements.
2Ease of manufacture
If the molding and run channel are attached separately, then each component can be optimized independently, but the attachment process becomes complex and time-consuming
Solution Approach 1:
The molding and run channel are manufactured as a single integrated component, allowing both to be optimized together during the molding process. This eliminates sequential attachment steps and reduces total assembly time while maintaining manufacturing flexibility through mold design variations.
3Adaptability or versatility
If multiple separate components are used for the rail portion, then functional requirements can be met, but the number of attachment steps increases
Solution Approach 1:
The molding assembly integrates multiple functions into a single component structure. The molding provides both the outer wall formation and the run channel sealing function simultaneously, reducing the number of discrete parts while maintaining all necessary functional capabilities for the rail portion assembly.

AI summary
A vehicle door sash structure includes a holding unit. The holding unit includes a guide locking portion arranged in a region of a run channel opposed in a vehicle inner-outer direction to a tip end rim of an inner beam portion in a state of temporary attachment after completion of attachment of a molding to an outer beam portion. The guide locking portion is inclined in a direction to guide the run channel to a position of completion of attachment while coming into contact with the tip end rim of the inner beam portion by an input of an attachment force in a direction to attach the molding to the run channel in the state of temporary attachment.
