Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for connecting adjustable spoiler blades to vehicles require complex alignment processes with multiple adjustment screws, leading to potential distortions and high tolerances due to numerous setting points.
Innovation Solution
A connecting device with a basic body featuring a Z clearance for fastening to spoiler kinematics and an alignment interface with XY clearance, allowing for separate alignment and setting of the spoiler blade in multiple positions, reducing distortions and simplifying the alignment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple adjustment screws with screw blades are used to align the spoiler blade, then the spoiler blade can be set in multiple positions, but the alignment process becomes complex and prone to distortions with high tolerances
Solution Approach 1:
The patent combines multiple adjustment screws with screw blades into a single connecting device that integrates both alignment and fastening functions. This single device includes a basic body with a fastening interface and an alignment interface, eliminating the need for separate adjustment screws and reducing alignment complexity while maintaining multiple positioning capability
Solution Approach 2:
The connecting device is designed as a multi-functional component that simultaneously provides alignment functionality (through the alignment interface with XY clearance) and fastening functionality (through the fastening interface with Z clearance). This universal device replaces multiple specialized components, simplifying the overall system while enabling multiple spoiler blade positions
2Strength
If multiple adjustment screws are used to fasten the spoiler blade, then the spoiler blade can be securely attached, but distortions occur and tolerances increase
Solution Approach 1:
The connecting device segments the fastening and alignment functions into two distinct interfaces: the alignment interface (with XY clearance) handles positioning and alignment, while the fastening interface (with Z clearance) handles secure attachment. This segmentation allows each interface to optimize its specific function, preventing distortions that occur when multiple screws attempt to perform both alignment and fastening simultaneously
Solution Approach 2:
The patent merges the alignment and fastening operations into a single connecting device that can perform both functions sequentially. The alignment interface first establishes precise positioning, then the fastening interface secures the connection, eliminating the cumulative errors and distortions that arise from using multiple adjustment screws
3Ease of operation
If separate alignment and fastening operations are performed, then the alignment process is simplified and distortions are reduced, but the device structure becomes more complex
Solution Approach 1:
The patent combines separate alignment and fastening operations into a single integrated connecting device. The basic body contains both the alignment interface (for XY positioning) and the fastening interface (for Z-axis attachment), allowing simplified sequential operations while maintaining a compact, unified device structure rather than requiring multiple separate components
