Vehicle Door Handle Bracket Assembly for Hands-Free Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing process of attaching a mounting bracket to a vehicle door panel requires both hands, making it inefficient and risking the bracket from falling before secure attachment.
Innovation Solution
The use of complementary coupling elements on the vehicle door panel and mounting bracket allows for the bracket to be positioned and secured in an intermediate assembly position, ensuring it remains attached until final secure attachment, using movements along specific axes to prevent detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional screwing method is used to attach mounting bracket to vehicle door panel, then secure attachment is achieved, but both hands are required making the process inefficient and risking bracket detachment
Solution Approach 1:
The attachment process is segmented into two distinct phases: a preliminary positioning phase using complementary coupling elements (allowing one-handed operation), and a final securing phase using screws or bolts. This segmentation allows the operator to complete positioning with one hand while the other hand prepares fastening tools, eliminating the need to hold the bracket with both hands simultaneously.
Solution Approach 2:
The complementary coupling elements perform preliminary positioning and temporary securing of the mounting bracket to the vehicle door panel before final attachment. The coupling elements engage preliminary, holding the bracket in correct position and preventing detachment during the subsequent screwing operation, enabling hands-free final securing.
2Productivity
If operator uses one hand to position mounting bracket and other hand to screw, then attachment process is simplified, but positioning precision and stability are compromised
Solution Approach 1:
The complementary coupling elements act as an intermediary mechanism between the mounting bracket and the vehicle door panel. These elements provide precise positioning guidance and temporary securing, ensuring accurate alignment without requiring the operator to manually hold the bracket. The intermediary coupling elements maintain positioning precision while enabling faster, one-handed operation.
3Loss of time
If mounting bracket is attached directly without preliminary positioning, then attachment is faster, but bracket may fall or misalign before secure attachment
Solution Approach 1:
The complementary coupling elements perform preliminary positioning and temporary securing of the mounting bracket before final screw attachment. This preliminary action ensures the bracket is correctly positioned and retained during the attachment process, preventing falls or misalignment, while the entire process remains rapid due to the simple coupling mechanism.
