Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door adjustment devices lack a cost-effective method for sensory detection of the absolute position of vehicle parts, leading to inefficient and noisy manual adjustments and inadequate securing mechanisms.
Innovation Solution
A device equipped with a sensor system that detects the angular position of a shaft, allowing for the determination of the absolute position of vehicle parts, combined with a switchable transmission for both electromotive and manual adjustment, enabling secure and smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a sensor device is added to detect the angular position of the shaft, then the measurement precision of vehicle part position is improved, but the device complexity increases
Solution Approach 1:
The shaft serves multiple functions: it transmits rotational movement from the output element to enable adjustment of the vehicle part, and simultaneously serves as the mounting base for the sensor device to detect angular position. This multi-functionality reduces the need for additional separate components, thereby improving measurement precision while minimizing the increase in device complexity.
2Adaptability or versatility
If both electromotive and manual adjustment modes are provided, then the adaptability of the device is improved, but the device complexity increases
Solution Approach 1:
The transmission is designed to be switchable between different operational states (electromotive mode and manual mode). This dynamic configuration allows the device to adapt to different adjustment requirements without requiring completely separate systems, thereby improving versatility while controlling the increase in device complexity through a unified switchable architecture.
3Object-affected harmful factors
If parallel running of parts in manual adjustment is avoided, then the harmful factors (noise and sluggishness) are reduced, but the ease of operation may be worsened
Solution Approach 1:
The design extracts and eliminates the parallel running configuration of parts that causes noise and sluggishness during manual adjustment. By reconfiguring the mechanical layout to avoid parallel running, the harmful factors are reduced while the adjustment function remains achievable through the optimized mechanical arrangement.
