Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation of furniture parts is used, then device complexity is reduced, but ease of operation deteriorates due to lack of intuitive control
Solution Approach 1:
The sensor device automatically detects physical state variables and retrieves corresponding movement profiles from data memory without requiring user intervention. The actuator then executes the appropriate movement pattern autonomously, allowing the furniture part to serve itself rather than requiring manual control mechanisms.
Solution Approach 2:
The patent replaces manual mechanical operation with an automated system comprising sensors that detect physical state variables, a data memory storing movement profiles, and an actuator that executes movements. This substitution of mechanical user interaction with sensor-actuator technology improves ease of operation while managing device complexity through electronic automation.
2Ease of operation
If automated movement control is implemented, then ease of operation is improved, but device complexity increases due to additional sensors and control systems
Solution Approach 1:
Movement profiles are pre-stored in the data memory, each associated with specific physical state variables. When the sensor detects a matching state variable, the corresponding pre-prepared movement profile is automatically retrieved and executed, eliminating the need for real-time complex control algorithms and reducing operational complexity.
Solution Approach 2:
The sensor device continuously monitors physical state variables of the movable furniture part and provides feedback to the control system. This feedback loop enables automatic retrieval of appropriate movement profiles from data memory and execution by the actuator, creating a closed-loop control system that improves ease of operation while managing complexity through systematic feedback processing.
3Adaptability or versatility
If movement profiles are pre-stored for all situations, then adaptability is improved, but loss of information increases due to memory requirements
Solution Approach 1:
Instead of storing all possible movement profiles universally, the system stores movement profiles locally in data memory that are specifically associated with particular physical state variables. This allows the system to adapt to different movement situations by retrieving only the relevant pre-stored profiles, providing adaptability while minimizing memory requirements by storing information only where needed.
