Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional foldable chairs are used for transforming premises, then the premises can be adapted between obstacle-free and seated configurations, but the transformation process becomes very laborious and time-consuming
Solution Approach 1:
The patent applies the dynamics principle by transforming static chairs into mobile, motor-driven seat rows that can automatically move between storage and operational positions. The seat rows are mounted on carriages with wheels that roll along guides, enabling dynamic reconfiguration without manual labor. The motorized propulsion system allows the seats to be automatically deployed or retracted based on operational requirements, dramatically reducing transformation time while maintaining adaptability.
Solution Approach 2:
The patent implements self-service through autonomous seat rows that can independently move themselves along the guides using integrated motor-propulsion systems. Each seat row is equipped with its own drive mechanism, allowing it to autonomously navigate to storage areas or deployment positions without requiring manual handling or external assistance, thereby eliminating the laborious transformation process.
2Adaptability or versatility
If conventional foldable chairs are used, then the premises can be transformed, but the chairs are not very comfortable and require manual placement and storage
Solution Approach 1:
The patent transforms static, manually-handled chairs into dynamic, motorized seat rows that automatically navigate along guides. The seat rows are mounted on wheeled carriages that can be propelled along the guide system, enabling easy repositioning without manual lifting or carrying. This dynamic system maintains the adaptability of the premises while dramatically improving ease of operation through automated movement.
Solution Approach 2:
The seat rows are equipped with self-propulsion capabilities through integrated motor systems, allowing them to autonomously move to storage or operational positions without requiring manual placement. The self-service mechanism includes automatic navigation along the guides and positioning at designated locations, eliminating the need for human intervention in seat handling.
3Extent of automation
If mobile seat assemblies with sliding guides are used, then the seats can be moved between stored and deployed positions, but the automation of movement and guide covering becomes complicated and expensive
Solution Approach 1:
The patent implements a dynamic automation system where seat rows are mounted on carriages with wheels that roll along guides, replacing complex sliding mechanisms. The motor-propulsion systems provide automated movement control, and the carriages include integrated guide covering mechanisms that automatically deploy panels to cover the guides when seats are in storage position. This dynamic approach simplifies the overall system while maintaining full automation capabilities.
Solution Approach 2:
The carriages are equipped with self-service mechanisms that automatically cover the guides with panels when the seat rows are in storage position. The guide covering system is integrated into the carriage structure and operates autonomously as the carriage moves into position, eliminating the need for separate, complex automation systems for guide coverage.
4Measurement precision
If motor-driven movement systems with PLC control are implemented, then precise control and synchronization of seat movements is achieved, but the system complexity increases
Solution Approach 1:
The patent implements feedback control through encoders that monitor the position of each carriage along the guides. The encoder signals are fed back to the PLC control system, which uses this information to precisely control the motor-propulsion systems and maintain accurate positioning. The feedback mechanism enables synchronized movement of multiple seat rows while providing real-time position data for control adjustments, achieving high precision without excessive system complexity.
