Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a mechanical locking system is used in the tilting mechanism, then the structure is simple and easy to manufacture, but the actuation delay is significant and response speed is slow
Solution Approach 1:
The patent replaces the purely mechanical locking system with an electronically controlled hydro-pneumatic system. Solenoid valves controlled by a central electronic unit regulate fluid flow to actuate the tilting mechanism, eliminating mechanical actuation delays and achieving response times of a few hundredths of a second.
Solution Approach 2:
The patent employs a hydro-pneumatic system where fluid pressure is used to actuate the tilting mechanism. This allows rapid engagement and disengagement of the locking system by controlling fluid flow through electronically operated valves, significantly reducing actuation delay compared to mechanical systems.
2Reliability
If the tilting locking system is actuated during deceleration on uneven surfaces, then the vehicle stability is compromised due to grip loss, but delaying the actuation reduces the ability to maintain balance at stops
Solution Approach 1:
The patent incorporates sensors that continuously monitor wheel grip conditions, vehicle tilt angle, and deceleration state. The central electronic unit processes this feedback information to determine the optimal moment to actuate the locking system, ensuring stability is maintained while avoiding actuation during grip loss conditions.
Solution Approach 2:
The patent implements a dynamic actuation strategy where the locking system engagement is adjusted based on real-time vehicle conditions. The system can automatically delay or advance actuation timing according to detected grip conditions, surface unevenness, and deceleration rate, optimizing both stability and balance maintenance.
3Ease of operation
If manual actuation of the locking system is required, then the system is simple to control, but the driver cannot respond quickly enough to maintain balance during sudden stops
Solution Approach 1:
The patent implements an automatic actuation system where the locking system is engaged and disengaged without driver intervention. The central electronic unit autonomously monitors vehicle conditions and actuates the locking mechanism at the optimal moment, eliminating the delay associated with manual driver response while maintaining operational simplicity through automatic control.
Solution Approach 2:
The system performs preliminary assessment of vehicle conditions through sensors before actuation is needed. By continuously monitoring grip conditions, tilt angle, and deceleration, the system is prepared to actuate the locking mechanism immediately when conditions warrant engagement, achieving rapid response without manual intervention.
4Stability of the object's composition
If the locking system is engaged during vehicle movement, then the tilting function is lost, but disengaging it too early causes imbalance on rough terrain
Solution Approach 1:
The patent uses continuous feedback from sensors monitoring vehicle speed, tilt angle, and surface conditions to determine the optimal disengagement timing. The central electronic unit processes this information to maintain the locking engagement just long enough to ensure stability on rough terrain while disengaging promptly when vehicle movement resumes, preserving the tilting function.
Solution Approach 2:
The patent implements dynamic timing control where the locking system engagement duration is adjusted based on real-time vehicle conditions. The system extends engagement slightly longer when detecting rough terrain or slow movement, and disengages more quickly when vehicle speed increases, optimizing both balance maintenance and tilting function preservation.
