Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the seat is elevated to provide various services, then the robot's versatility is improved, but a gap is formed between the seat and main body that may introduce foreign substances
Solution Approach 1:
A gap cover is introduced as an intermediary component between the seat and main body. The gap cover moves forward and backward relative to the seat base and is spring-pressed to maintain contact with the inclined surface, dynamically sealing the gap while allowing seat elevation motion.
Solution Approach 2:
The gap cover is designed to move dynamically with the seat base during elevation. It includes a front cover and side covers that can shift position, with at least one bearing contacting the inclined surface to enable smooth movement while maintaining the sealing function throughout the elevation range.
2Object-affected harmful factors
If the gap cover is spring-pressed forward to minimize the gap, then the sealing effect is improved, but the device complexity increases
Solution Approach 1:
The spring mechanism provides self-service by automatically pressing the gap cover forward without requiring external actuation. The spring is disposed between the seat base and gap cover, creating a passive sealing system that maintains contact with the inclined surface through elastic force alone.
Solution Approach 2:
The complex active control system for gap sealing is replaced by extracting only the essential sealing function and implementing it through a simple spring-pressed passive mechanism. This removes unnecessary complexity while maintaining the sealing effect.
3Ease of operation
If multiple actuators are used to elevate the seat, then the elevation control is improved, but the device complexity increases
Solution Approach 1:
The elevation mechanism is segmented into multiple independent actuators spaced apart and driven independently. This segmentation allows each actuator to handle specific elevation tasks, improving control precision and stability while maintaining modular simplicity.
Solution Approach 2:
The multiple independent actuators serve universal elevation functions, with each actuator capable of performing the same basic elevation task. This multi-functionality approach simplifies the overall system design by using identical components for different positions, reducing the need for specialized mechanisms.
