Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a passive sensor pad system is used to detect patient pressure, then the system can sense bottoming out of the patient, but the response is not sharp enough and the pressure in the mattress is too low to efficiently support the patient by the time the response is received
Solution Approach 1:
The active sensor pad proactively monitors pressure distribution and detects potential bottoming out conditions before they occur, rather than passively reacting after the patient has already bottomed out. This allows the system to maintain optimal supporting pressure and provide timely therapeutic intervention.
Solution Approach 2:
The system continuously monitors pressure distribution through the sensor pad and provides real-time feedback to the control unit, which automatically adjusts mattress pressure in response to detected changes, creating a closed-loop control system that maintains optimal therapeutic pressure.
2Adaptability or versatility
If additional components such as a second compressor and extended sensor pad coverage are added to improve system functionality, then the system can control head and leg zones, but the manufacture cost increases and the risk of malfunction increases
Solution Approach 1:
The single compressor is designed to serve multiple functions by controlling different zones of the mattress through intelligent pressure distribution. The sensor pad covers the entire mattress surface, allowing one component to perform what previously required multiple separate components, thereby reducing system complexity while maintaining versatility.
Solution Approach 2:
The system merges the functions of multiple compressors into a single compressor that can independently control different mattress zones through sophisticated pressure management, reducing the total number of components while maintaining the ability to provide targeted therapy to head, body, and leg zones.
3Extent of automation
If a fully automated mattress system with extended sensor pad coverage is implemented, then the system can control head and leg zones, but additional components are required which increase manufacture cost and malfunction risk
Solution Approach 1:
The mattress system is designed to be self-regulating, with the sensor pad and control unit automatically adjusting pressure without requiring manual intervention or additional monitoring components. This self-service capability reduces the need for redundant safety components while maintaining high automation levels.
Solution Approach 2:
The system incorporates proactive monitoring and adjustment mechanisms that prevent malfunction conditions before they occur, such as detecting pressure imbalances or sensor issues early in the operation cycle, thereby maintaining high reliability without requiring excessive redundant components.
4Device complexity
If manual manipulation or semi-automated systems are used, then the system structure is simpler, but trained operators are required to set initial pressure settings and adjust supporting pressure levels
Solution Approach 1:
The mattress system automatically performs pressure setting and adjustment functions that previously required trained operators, using the sensor pad to detect patient characteristics and the control unit to calculate and implement optimal pressure settings, thereby simplifying operation while maintaining a relatively simple physical structure.
Solution Approach 2:
The system performs preliminary pressure optimization automatically upon patient contact, eliminating the need for manual initial setup by trained operators. The sensor pad detects patient body characteristics and the control unit pre-configures optimal pressure settings before therapy begins.
5Adaptability or versatility
If conventional mattress systems with multiple components are used, then the system can provide alternating pressure therapy, but the manufacture cost is high and the risk of malfunction is increased
Solution Approach 1:
The single compressor and integrated control unit are designed to provide multiple therapy modes (alternating pressure, continuous pressure, pulsating pressure) through software control rather than requiring separate hardware systems for each therapy type, significantly reducing manufacturing cost while maintaining therapeutic versatility.
Solution Approach 2:
The system achieves different therapy modes by changing operational parameters (pressure levels, cycle timing, inflation/deflation rates) of a single compressor system rather than requiring multiple dedicated compressors, thereby reducing component count and manufacturing cost while maintaining full therapy capability.

AI summary
The present invention provides a mattress system (1) devised to achieve a function of automatic detection, mainly comprising: a mattress (2) having a simple structure; a control unit (3) equipped with a unique user interface (31) for caregivers to simultaneously adjust three major functions, namely, therapy mode, therapy intensity and comfort level; and a connection pipe (4) for supplying air and power. The system (1) is further provided with a built-in auto-setting function to sense the body characteristics of the patient (39) lying on the mattress (2) and determine an effective supporting pressure range for the patient (39). By detecting a pressure difference representing the body characteristics of the patient (39) lying on the mattress (2) and comparing with the data stored in a built-in database, the system (1) can always provide the patient (39) with not only a well-proved therapeutic effect through the auto-setting function, but also an adjustable comfort level on the patient's request through the user interface (31).
