Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual intervention is used to deploy and retract seating risers, then ease of operation is maintained, but productivity is reduced and binding may occur on uneven terrain
Solution Approach 1:
The seating riser system incorporates a powered telescopic mechanism with automatic alignment capabilities that enables the system to deploy and retract itself without manual intervention. The laser/sensor feedback loop continuously monitors and corrects misalignment, allowing the system to self-adjust to uneven terrain and prevent binding during movement.
Solution Approach 2:
The patent replaces manual mechanical operation with an automated powered telescopic mechanism. The system uses laser sensors and feedback control to substitute human judgment and adjustment with automated detection and correction, eliminating the need for operators to manually guide the risers during deployment and retraction.
2Productivity
If automated deployment mechanism is added, then productivity is improved, but device complexity increases
Solution Approach 1:
The system employs a laser/sensor feedback loop that continuously monitors the alignment and position of seating risers during deployment and retraction. The sensor detects misalignment conditions and feeds this information back to the powered telescopic mechanism, which automatically adjusts to correct the deviation, ensuring smooth operation on uneven terrain.
Solution Approach 2:
The powered telescopic mechanism incorporates dynamic adjustment capabilities that allow real-time modification of deployment parameters. The system can adapt its movement pattern, speed, and alignment corrections based on terrain conditions detected by the laser sensors, enabling flexible operation across varying surface conditions.
3Adaptability or versatility
If telescopic mechanism is used for uneven terrain, then adaptability is improved, but reliability decreases due to potential binding
Solution Approach 1:
The laser/sensor feedback loop continuously monitors the relative positioning and alignment of telescopic sections during movement. When misalignment or potential binding conditions are detected, the system receives feedback signals that trigger automatic correction mechanisms, adjusting the telescopic motion to maintain proper alignment and prevent binding on uneven terrain.
Solution Approach 2:
The system performs preliminary alignment adjustments and preventive corrections before binding can occur. The laser sensors detect potential misalignment issues in advance, allowing the powered telescopic mechanism to proactively adjust its movement pattern and prevent binding conditions from developing during deployment or retraction on uneven surfaces.
