Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lifting device is connected to local power grids via power connection, then the drive control and drive device can be supplied with energy, but the lifting device becomes dependent on specific power supply networks and cannot operate location-independently
Solution Approach 1:
The patent extracts the energy supply function from the external power grid and relocates it to an onboard energy store (battery) integrated into the lifting device. This allows the drive control and drive device to operate independently of local power networks, enabling location-independent operation while maintaining operational reliability.
Solution Approach 2:
The energy store serves as a universal power source that can operate the lifting device in any location without requiring adaptation to different power supply networks. This multi-functional approach combines energy storage, power supply, and operational independence into a single system.
2Adaptability or versatility
If the drive control is adapted to different power supply networks in respective countries, then the lifting device can be operated in different locations, but the device complexity and production costs increase
Solution Approach 1:
The patent removes the need for adapting drive control to different power supply networks by extracting the power supply function from external grids and replacing it with a standardized onboard energy store. This eliminates the complexity of creating region-specific control adaptations.
Solution Approach 2:
The energy store provides a standardized voltage output that remains constant regardless of location, eliminating the need to change control parameters for different power networks. This standardization simplifies the drive control system while maintaining international operability.
3Use of energy by moving object
If a direct power connection via cable to local supply network is required, then the lifting device can receive continuous energy supply, but the installation site becomes limited by local power supply connections
Solution Approach 1:
The patent extracts the power connection requirement from the installation environment and integrates an energy store directly into the lifting device. This eliminates the need for cable connections to local supply networks, allowing installation at any location while maintaining energy supply continuity through the onboard battery.
4Duration of action of moving object
If multiple individual accumulators are connected via plug strip to charging station, then the lifting device can be recharged, but the charging station must be adapted to respective supply voltage
Solution Approach 1:
The energy store is designed with standardized electrical parameters (voltage, current, connection interface) that remain constant regardless of location. This standardization allows the same charging infrastructure to be used worldwide without adaptation to different supply voltages, while still enabling extended operational duration through recharging.
