Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a platform is driven by rotational and oscillating movements with adjustable amplitude and speed, then the mobilization effect is improved, but the device complexity increases and the oscillation amplitude is limited by the structure
Solution Approach 1:
The patent applies dynamics by making the oscillation characteristics variable and adaptive. The control unit dynamically adjusts oscillation parameters (amplitude, frequency, direction) based on subject response and treatment requirements, transforming a static mechanical system into a dynamic, programmable one that can adapt to different rehabilitation needs without structural modifications
Solution Approach 2:
The invention changes operational parameters (oscillation amplitude, frequency, direction, randomness) through software control rather than mechanical reconfiguration. The programmable control unit allows infinite variation of oscillation parameters within mechanical limits, enabling diverse treatment protocols without adding complex mechanical adjustment mechanisms
2Device complexity
If the oscillation movements are limited by the structures implemented, then the device complexity is reduced, but the adaptability and efficiency of treatment are reduced
Solution Approach 1:
The patent achieves universality through a single oscillating platform capable of performing multiple treatment functions by varying oscillation parameters. The same mechanical structure can deliver different treatment protocols (varying amplitudes, frequencies, directions, and randomness patterns) through programmable control, making one device suitable for various rehabilitation conditions and subject needs
Solution Approach 2:
The system dynamically adapts oscillation characteristics during treatment based on real-time subject response. The control unit can modify oscillation parameters on-the-fly, allowing the same device to adapt to different phases of rehabilitation and individual subject requirements without mechanical reconfiguration
3Ease of manufacture
If the oscillation amplitude is limited by the structures implemented, then the manufacturing is simplified, but the treatment possibilities are reduced
Solution Approach 1:
The invention maximizes treatment possibilities within fixed mechanical amplitude limits by implementing fine-grained control over oscillation parameters. The programmable system varies frequency, duty cycle, direction sequences, and randomness patterns to create diverse treatment effects from a limited amplitude range, achieving therapeutic versatility without expanding mechanical travel
4Adaptability or versatility
If a double pivot connection with gimbal mechanism is used, then the degrees of freedom and random oscillation capability are improved, but the device complexity increases
Solution Approach 1:
The patent adds rotational freedom around the vertical axis (azimuthal oscillation) to the traditional pitch oscillation, creating three-dimensional oscillation capability. The gimbal mechanism enables oscillations in multiple planes and directions, transforming a one-dimensional oscillation system into a multi-dimensional one, allowing random oscillation patterns and comprehensive vertebral axis mobilization

AI summary
This apparatus for mobilization of the body comprises a receiving platform (1) which is movable in relation to a fixed chassis and which is designed to support a subject who is to be treated in a standing position. The platform (1) is connected to the chassis by a double pivot connection, and it is driven in an oscillating movement, in relation to an axis passing substantially through its centre, by means of actuators (8, 9) which are each connected by a pivot joint to a shaft (6) connected to said platform, said actuators (8, 9) themselves being articulated on the chassis.
