Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If step systems are manufactured to customer specifications with customized system sizes and variables, then adaptability to different customer requirements is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The step system is divided into modular components including step modules, sealing strips, and adjusting elements that can be independently configured and assembled. This segmentation allows customization of system variables and sizes by selecting different module combinations without increasing overall system complexity
Solution Approach 2:
The patent implements universal adjusting elements and mounting mechanisms that can accommodate multiple configuration options and customer requirements. The sealing strip assembly with adjustable mounting positions provides multi-functionality, allowing the same basic design to serve different system sizes and customer specifications
2Manufacturing precision
If the sealing strip is fixed rigidly to the step module, then manufacturing precision and assembly simplicity are improved, but adaptability to different assembly heights and angles is worsened
Solution Approach 1:
The sealing strip assembly incorporates adjustable mounting mechanisms that allow dynamic reconfiguration of assembly height and angle. The adjusting elements enable the sealing strip to be positioned at different heights and angles relative to the step module while maintaining secure attachment and sealing effectiveness
3Adaptability or versatility
If different assembly heights and angles are achieved by manufacturing separate custom systems, then adaptability is improved, but productivity and waiting times are worsened
Solution Approach 1:
The system uses modular step modules and sealing strip assemblies that can be pre-manufactured and then quickly configured for different applications. This segmentation enables rapid assembly and customization without requiring separate manufacturing processes for each configuration
Solution Approach 2:
The patent implements adjustable parameters for assembly height and angle through mechanical adjusting elements. These parameters can be changed by repositioning existing components rather than manufacturing new parts, allowing rapid adaptation to different customer requirements while maintaining production efficiency

AI summary
The present invention relates to a modular step sealing assembly (1) for a step system implemented in a vehicle, in particular a rail vehicle. This assembly comprises: - a step module (2) which, by means of a drive unit, can be moved along a movement axis (A) from a retracted position to an extended position and vice versa, wherein the step module (2) has a step surface (3) which extends in a step surface plane oriented parallel to the movement axis (A), and wherein the step module (2) has a step module front edge (4) at a front end directed outwards towards the vehicle; - a sealing strip (5) which is attached to the step module front edge (4) and extends along the step module front edge (4) substantially in a sealing strip plane.wherein the sealing strip (5) and the step module (2) define a vertical assembly height (H) perpendicular to the axis of movement (A), and wherein the sealing strip (5) and the tread surface (3) are arranged at an angle (β) to each other, characterized in that the assembly height (H) and the angle (β) between the sealing strip (5) and the tread surface (3) are adjustable via a module mechanism.
