Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bearing pressure between railway wheels and rails is increased to prevent derailment, then guidance stability is improved, but wear on rubber wheels increases due to deformation
Solution Approach 1:
The patent implements a dynamic regulation system that automatically adjusts the position of railway wheels relative to the working machine during operation. This dynamic adjustment allows the system to maintain optimal bearing pressure on rails for guidance stability while preventing excessive pressure that would cause rubber wheel deformation and wear, resolving the contradiction between reliability and harmful effects.
Solution Approach 2:
The patent employs a feedback mechanism through the regulating device that continuously monitors and adjusts the railway wheel position based on operating conditions. This feedback control enables the system to maintain the bearing pressure within optimal ranges, ensuring sufficient guidance stability without causing excessive wear on rubber wheels, thus resolving the technical contradiction.
2Power
If the bearing pressure between rubber wheels and rails is increased to maintain drive and brake power, then driving capability is improved, but the working machine may derail due to insufficient guidance pressure from railway wheels
Solution Approach 1:
The regulating device dynamically adjusts the railway wheel position to optimize the distribution of bearing pressure between rubber wheels and railway wheels. This dynamic regulation ensures that sufficient pressure is maintained on rubber wheels for drive and brake power while simultaneously ensuring adequate guidance pressure from railway wheels to prevent derailment, resolving the contradiction between power and reliability.
3Ease of operation
If manual regulation of railway wheel position is used to optimize bearing pressure, then operational flexibility is improved, but safety risks increase due to operator error and distraction
Solution Approach 1:
The patent implements a self-regulating system where the regulating device automatically adjusts the railway wheel position without requiring continuous manual intervention. This self-service mechanism maintains optimal bearing pressure distribution while eliminating safety risks associated with operator error and distraction, resolving the contradiction between ease of operation and reliability.
Solution Approach 2:
The automatic regulating device uses feedback control to continuously monitor and adjust railway wheel position, replacing manual regulation. This eliminates the safety risks of operator error and distraction while maintaining the ability to optimize bearing pressure, thus resolving the contradiction between operational flexibility and safety risk.
4Adaptability or versatility
If the bearing pressure distribution changes during varying loading of working tools, then adaptability to different working conditions is improved, but maintaining optimal pressure balance becomes difficult
Solution Approach 1:
The regulating device is designed to dynamically respond to changing loading conditions by automatically adjusting the railway wheel position. This dynamic adaptation maintains optimal bearing pressure balance regardless of varying loads from working tools, resolving the contradiction between adaptability and ease of operation.
Solution Approach 2:
The feedback mechanism in the regulating device continuously monitors bearing pressure distribution and automatically adjusts railway wheel position in response to varying loading conditions. This maintains optimal pressure balance without requiring manual intervention, resolving the contradiction between adaptability to different working conditions and the difficulty of maintaining pressure balance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances safety and operational efficiency by automating the regulation of railway wheels, reducing manual intervention and wear on rubber wheels, and adapting to changing conditions like temperature and load.
Implementation Method 1
pressing the railway wheels harder against the rails by means of power generating means, e.g. hydraulic cylinders
Implementation Method 2
their bearing surfaces against the upper sides of the rails become so small which deform the rubber wheels considerably in case the bearing pressure against the rails become too large
Implementation Method 3
the bearing pressure between the railway wheels and the rails has to be sufficient large such that the working machine doesn't derail
