Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding vehicle doors require complex adjustments to guide mechanisms, often resulting in structural complexity and the risk of losing the original timing during position adjustments, leading to inefficiencies and potential quality issues.
Innovation Solution
A sliding vehicle door design featuring a carriage with an eccentric mechanism that allows precise adjustment by rotating the eccentric relative to the carriage, enabling horizontal translation along a longitudinal axis without altering the initial wedging, using a tool to rotate the eccentric and fine-tune the position, and a retaining piece for secure assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the guide mechanism position is adjusted by loosening screws, then the position can be modified, but the original timing may be lost and the process becomes complex
Solution Approach 1:
The patent employs an eccentric mechanism that changes the positional parameter of the guide mechanism through rotational movement. The eccentric's offset distance creates a controlled translation of the carriage along the longitudinal axis, enabling precise position adjustment without complex procedures. The parameter being changed is the angular position of the eccentric, which directly translates to linear position adjustment of the guide mechanism.
2Adaptability or versatility
If the guide mechanism position is adjusted by loosening screws, then the position can be modified, but the original timing is lost
Solution Approach 1:
The eccentric mechanism is pre-configured with a specific offset distance that determines the adjustment range. The finger inserted into the vertical buttonhole acts as a preliminary constraint that guides the adjustment process and prevents excessive or incorrect positioning. This preliminary configuration ensures that adjustments remain within acceptable limits and maintain the original timing relationships.
Solution Approach 2:
The vertical buttonhole structure provides visual and physical feedback during the adjustment process. As the eccentric rotates and the carriage translates, the finger's engagement with the buttonhole gives immediate feedback on the position achieved. This feedback mechanism allows operators to verify that the original timing is maintained while achieving the desired position adjustment.
3Adaptability or versatility
If complex adjustment procedures are used, then position can be modified, but manufacturing time increases
Solution Approach 1:
The eccentric mechanism is designed to be self-contained and self-explanatory. The single rotational movement automatically produces the desired linear adjustment without requiring multiple steps, tools, or operations. The mechanism serves itself by converting simple rotational input directly into the required positional adjustment, eliminating the need for complex adjustment procedures and improving manufacturing efficiency.

Implementation Method 1
the carriage comprises an eccentric provided with a finger emerging from the outer surface and capable of being inserted into a vertical buttonhole of the box, the adjustment of the position of the carriage on the box being produced by the rotation of the eccentric relative to the carriage, causing a horizontal translation of said carriage along the box
