Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller devices for single-track vehicles, such as bicycles and motorcycles, fail to simulate realistic driving conditions due to fixed positioning, leading to falsified test results and exposure to dangerous environmental influences, and lack the ability to handle various test scenarios effectively.
Innovation Solution
A roller device with movable fastening units and interchangeable rollers, allowing wheels to contact the roller surface parallel to the axis, and featuring joints and linear guides for relative movement, simulating realistic driving conditions and enabling various test cases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the single-track vehicle is firmly positioned on the roller device using fixed fastening units, then the vehicle stability during testing is improved, but the test results become falsified and do not reflect real driving conditions
Solution Approach 1:
The fastening unit is designed with a joint that allows the wheel receptacle to move relative to the receiving unit along a pivot axis. This dynamic capability enables the vehicle to pivot and change position during testing, simulating real driving conditions while maintaining adequate stability through the constrained movement along a specific axis.
2Stability of the object's composition
If fixed positioning is used to ensure vehicle stability, then the vehicle remains stationary during testing, but the ability to simulate various driving scenarios is reduced
Solution Approach 1:
The movable wheel receptacle allows the vehicle to pivot along a first pivot axis, enabling simulation of cornering and lateral movement scenarios. The interchangeable roller design further enhances versatility by allowing different roller configurations to simulate various road conditions.
Solution Approach 2:
The roller device is designed with interchangeable rollers that can be swapped depending on the test case, allowing the same device to simulate different subsurface conditions and road types. The fastening unit's movable design also provides multi-functionality by accommodating various vehicle positions and test scenarios.
3Measurement precision
If sensors and the single-track vehicle are exposed to real environmental conditions during road travel, then real-world data can be collected, but measurement deviations, damage, and injuries may occur
Solution Approach 1:
The roller device serves as an intermediary between the vehicle and real road conditions. It provides a controlled environment that simulates driving scenarios without exposing the vehicle and sensors to dangerous environmental factors such as traffic, weather, and road hazards, while still collecting meaningful test data.
4Device complexity
If the wheel receptacle is fixed relative to the receiving unit, then the structure is simpler, but the vehicle cannot pivot or simulate cornering conditions
Solution Approach 1:
The fastening unit incorporates a joint that enables the wheel receptacle to move relative to the receiving unit along a pivot axis. This adds dynamic capability to simulate vehicle cornering and lateral movements while maintaining relatively simple structural implementation through a single degree of freedom movement.
