Solution Overview
Problem
Current calibration brackets for advanced driver assistance systems (ADAS) are unstable after mounting calibration elements, leading to potential calibration inaccuracies and safety issues due to the instability of the cross beam.
Innovation Solution
A calibration bracket design featuring a base, fixed and movable vertical rods, a brake member to provide friction, and a cross beam that moves with the movable rod, ensuring stability through a friction force, allowing for secure mounting of calibration elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a calibration element is mounted on the cross beam of a calibration bracket, then the calibration function is achieved, but the cross beam becomes unstable and easy to fall
Solution Approach 1:
The movable vertical rod is nested within the fixed vertical rod, with the cross beam nested on the movable vertical rod. This nested structure allows the cross beam to be supported by the movable rod while the movable rod slides within the fixed rod, providing stability without requiring additional external support structures.
Solution Approach 2:
The calibration bracket employs a dynamic structure where the movable vertical rod can slide along the fixed vertical rod to adjust the height and position of the cross beam. This dynamic adjustment capability allows the system to adapt to different calibration requirements while maintaining stability through the brake member when positioned.
2Adaptability or versatility
If the cross beam is made adjustable for different calibration positions, then the adaptability is improved, but the stability and reliability decrease
Solution Approach 1:
The system uses a dynamic structure where the movable vertical rod can be adjusted to different positions along the fixed vertical rod, allowing the cross beam to be positioned at various heights. The brake member is engaged during calibration to lock the position, providing stability when needed while maintaining adjustability when the brake is released.
Solution Approach 2:
The brake member acts as an intermediary mechanism between the movable vertical rod and the fixed vertical rod. It provides friction-based locking to hold the movable rod at the desired position, enabling the system to transition between adjustable and stable states without compromising either function.
3Reliability
If a brake member is added to provide friction force for stability, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The brake member serves as a simple intermediary component that introduces friction-based locking between the movable and fixed vertical rods. This single component provides the necessary stability by preventing slippage during calibration while adding minimal structural complexity to the overall system.
