Vehicle Part Adjustment Device with Transitional Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door adjustment systems experience abrupt changes between holding and release positions, leading to unpredictable and uncomfortable user experiences, along with potential service life issues due to temperature-related actuating noises and significant differences in blocking and free movability.
Innovation Solution
An electronic control device that initially actuates the driving device for a short power-operated adjustment in the desired direction before switching to the release position, allowing for a transitional adjusting movement to smooth the transition from power-operated to manual adjustment, avoiding abrupt changes and ensuring the driving device neither opposes nor supports manual adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the driving device is switched abruptly from holding position to release position, then the manual adjustment can be permitted quickly, but the transition becomes unpredictable and uncomfortable for the user
Solution Approach 1:
The control device performs a preliminary action by initially actuating the driving device for a power-operated adjustment in the desired direction before switching to the release position. This preliminary movement prepares the system for the transition, making the change from power-operated to manual adjustment less abrupt and more predictable for the user.
Solution Approach 2:
The system dynamically adjusts its behavior during the transition phase. The driving device is actuated to produce a transitional adjusting movement that smoothly bridges the gap between the holding position and the release position, creating a dynamic and adaptive transition rather than an abrupt static change.
2Reliability
If the driving device is held in holding position, then the second vehicle part is securely blocked, but the transition to free movability creates actuating noises and wear
Solution Approach 1:
The system performs a preliminary power-operated adjustment movement before releasing the blocking function. This preliminary action allows the driving device to transition smoothly from the blocked state to the free movability state, reducing sudden mechanical impacts that cause noises and wear during the switching process.
Solution Approach 2:
The transitional adjusting movement acts as a cushioning mechanism during the transition from holding to release position. By introducing this intermediate movement phase, the system reduces the shock and stress on mechanical components during the switching process, thereby reducing wear and actuating noises.
3Manufacturing precision
If the driving device blocks the second vehicle part in holding position, then power-operated adjustment is precise, but the abrupt release creates unpredictable behavior
Solution Approach 1:
The control device performs a preliminary power-operated adjustment in the desired direction before switching to the release position. This preliminary action maintains the precision of the power-operated system while adding a predictable transitional phase that makes the overall behavior more foreseeable for the user.
Solution Approach 2:
The system maintains continuity of useful action by actuating the driving device to produce a transitional adjusting movement. This continuous action bridges the gap between the precise blocked state and the free movability state, ensuring that the transition is smooth and predictable rather than abrupt.
