Spring-Loaded Dummy Stop Element for Precise Body Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for adjusting body components in vehicles, such as hoods and tailgates, are time-consuming and imprecise due to manual adjustment with dummy buffers, which can be displaced by varying closing forces and speeds, and adjustments without dummy buffers require multiple iterations.
Innovation Solution
A dummy buffer with a resiliently mounted stop region and locking mechanism, featuring a spring mechanism to compensate for closing forces and speeds, and a remote locking mechanism to fix the stop position, allowing simultaneous adjustment of multiple components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment with dummy buffers is used, then body components can be adjusted to desired position, but adjustment precision deteriorates due to dummy buffer displacement from varying closing forces and speeds
Solution Approach 1:
The dummy buffer incorporates a spring element that dynamically adapts to varying closing forces and speeds. The spring compresses or extends based on the applied force, maintaining consistent contact between the stop element and body structure regardless of closing conditions, thereby ensuring precise distance determination.
Solution Approach 2:
The system changes the physical state of the dummy buffer by introducing a spring mechanism that alters the contact pressure and position of the stop element. This parameter change compensates for variations in closing force and speed, maintaining consistent measurement conditions for accurate distance determination.
2Manufacturing precision
If adjustment without dummy buffers is used, then manufacturing precision can be improved, but productivity deteriorates due to multiple opening and closing operations required
Solution Approach 1:
The dummy buffer with spring element performs preliminary positioning and preload application in a single operation. The spring mechanism pre-compensates for closing forces, allowing the stop element to be positioned correctly on the first attempt, eliminating the need for multiple iterative adjustments.
Solution Approach 2:
The spring-loaded dummy buffer acts as an intermediary tool that facilitates precise adjustment in a single operation. It mediates between the body component and body structure, providing consistent contact and preload that enables accurate distance determination without requiring multiple trial operations.
3Ease of operation
If dummy buffer is pressed in by closing forces, then ease of operation is maintained, but measurement accuracy deteriorates as correct distance cannot be determined
Solution Approach 1:
The spring element provides dynamic compensation for closing forces. As the dummy buffer is pressed in during closing, the spring compresses proportionally, maintaining constant contact between the stop element and body structure. This dynamic response ensures that the measured distance remains accurate regardless of the magnitude of closing forces applied.
