Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If impact bars are rigidly fastened to the machine frame, then the structure is simple and stable, but the impact bars cannot be adjusted and wear unevenly
Solution Approach 1:
The patent transforms the static impact bar system into a dynamic one by introducing adjustable positioning devices. Each impact bar is equipped with a positioning device that can change its position relative to the machine frame, allowing the system to adapt between different operational requirements while maintaining structural stability through controlled adjustability.
Solution Approach 2:
The patent implements self-adjustment capability through automatic positioning devices that can adjust impact bar positions without manual intervention. The system includes sensors and actuators that automatically detect wear patterns and adjust positions to maintain optimal performance, eliminating the need for frequent manual shutdowns and adjustments.
2Manufacturing precision
If impact bars are manually adjusted, then position accuracy can be maintained, but the adjustment process is complex and requires machine shutdown
Solution Approach 1:
The system automatically adjusts impact bar positions using motorized positioning devices with integrated sensors. The automatic adjustment mechanism maintains position accuracy within specified tolerances while operating continuously, eliminating the need for manual intervention and machine shutdowns that would disrupt production.
Solution Approach 2:
The patent replaces manual mechanical adjustment with automated electromechanical positioning systems. Motors and sensors substitute for manual operations, enabling precise position control while the machine remains operational, thereby maintaining manufacturing precision without sacrificing productivity.
3Duration of action of stationary object
If impact bars are frequently adjusted, then wear can be reduced, but adjustment time and operational costs increase
Solution Approach 1:
The patent enables continuous operation by implementing automatic positioning devices that adjust impact bar positions during normal production cycles. The system continuously monitors wear patterns and makes incremental adjustments without interrupting the manufacturing process, thereby extending impact bar service life without incurring adjustment downtime.
Solution Approach 2:
The automatic positioning system performs self-adjustment based on real-time wear detection, eliminating the need for scheduled manual adjustments. This extends the service life of impact bars by maintaining optimal positions continuously while avoiding the productivity losses associated with manual adjustment intervals.
4Measurement precision
If multiple positioning devices are used for each impact bar, then adjustment precision is improved, but device complexity increases
Solution Approach 1:
The patent divides the positioning system into modular units, with each impact bar equipped with its own independent positioning device. This segmentation allows for localized precision adjustment without requiring a complex centralized system, reducing overall system complexity while maintaining high measurement precision through distributed sensing and actuation.

Facilitates quick, error-free adjustment of impact bars, maintaining consistent product quality and reducing machine wear, thereby minimizing downtime and operational costs.
Implementation Method 1
a plurality of positioning devices (6) connected to one another and driven by means of at least one common drive unit (20) in order to obtain a displacement of all the impact bars (5)
Implementation Method 2
The unbalanced masses or unbalanced shafts installed in the vibrating table are preferably driven by at least one electric motor. In this case the vibrating table can be set in a predominantly vertical vibrating movement. The unbalanced masses or unbalanced shafts are preferably set in rotation by the servomotor, wherein as a result the vibrating table carries out a predominantly vertical up and down movement.
