Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for aligning deformed vehicles face challenges as there is a risk that the supports and supported portions of the vehicle may move during the deformation process, leading to inadequate deformation and subsequent re-alignment requirements.
Innovation Solution
The method involves using motion sensing measuring units, including accelerometers and gyroscopes, to monitor the movements of supported vehicle portions during deformation, ensuring that only intended parts move and allowing for real-time monitoring and correction of any unwanted movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If supports are used to hold vehicle portions during deformation, then the vehicle can be deformed, but the supports may move during the deforming process causing inadequate deformation
Solution Approach 1:
The patent applies feedback by using motion sensing measuring units (accelerometers and gyroscopes) to continuously monitor the position and movement of supported vehicle portions during the deformation process. The measured data is fed back to the control system, which adjusts the deforming force in real-time to compensate for any support movement, ensuring accurate alignment is achieved despite support instability.
Solution Approach 2:
The patent replaces reliance on purely mechanical support stability with an electronic sensing and control system. Instead of depending solely on the mechanical rigidity of supports, the system uses accelerometers and gyroscopes to detect movement and employs electronic control to adjust the deforming process, substituting mechanical certainty with sensor-based compensation.
2Measurement precision
If motion sensing measuring units are added to monitor supported portions, then movement detection capability is improved, but device complexity increases
Solution Approach 1:
The patent changes the measurement parameters by using accelerometers to measure acceleration and gyroscopes to measure angular velocity, then integrating these measurements to derive position and orientation. This multi-parameter approach provides comprehensive movement detection while using commercially available sensor modules that integrate multiple functions, balancing measurement precision with system complexity.

AI summary
A method for of aligning a vehicle includes the steps of: supporting a first portion (19A, 19B) of the vehicle, deforming the vehicle by applying a force to a second portion (5) of the vehicle, positioning at least one motion sensing measuring unit (9A, 9B) including at least one accelerometer on the supported first portion (19A, 19B) of the vehicle before the deforming step, and tracking any movements of the supported first portion (19A, 19B) of the vehicle during the deformation by means of the motion sensing measuring unit (9A, 9B). An arrangement for aligning a vehicle is also provided.
