Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external wiring is provided for power supply and signal transmission, then the control element can operate reliably, but the installation becomes complex and time-consuming
Solution Approach 1:
The patent extracts the power supply and signal transmission functions from external wiring by integrating energy recovery units (photovoltaic modules, piezoelements, induction coils) directly into the control element. This allows the control element to generate its own power and transmit signals wirelessly, eliminating the need for complex external wiring while maintaining operational reliability
Solution Approach 2:
The control element becomes self-sufficient by incorporating energy recovery units that harvest energy from ambient light, mechanical pressure, or electromagnetic fields. This self-powering mechanism eliminates dependency on external power wiring, simplifying installation while ensuring continuous reliable operation
2Duration of action of stationary object
If external wiring is provided for power supply, then the control element can function continuously, but the installation time increases
Solution Approach 1:
The patent removes the time-consuming wiring step by extracting the power supply function from external infrastructure. The integrated energy recovery units enable plug-and-play installation without requiring electrical connections, dramatically reducing installation time while ensuring continuous operation through autonomous power generation
Solution Approach 2:
The control element performs self-installation in terms of power connection by automatically harvesting energy from the environment. This eliminates the need for professional electricians and complex wiring procedures, reducing installation time from hours to minutes while maintaining continuous operational capability
3Ease of operation
If wireless signal transmission is implemented, then the signal transmission becomes simpler, but power supply still requires wiring
Solution Approach 1:
The patent merges the power supply and signal transmission functions by integrating energy recovery units with the wireless communication module. This combination allows both power generation and signal transmission to be handled internally without external wiring, fully realizing wireless operation and simplifying both installation and maintenance
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
Enables wireless operation without external wiring, simplifies installation, and reduces energy consumption, making it suitable for retrofitting and upgrading elevator systems.
Implementation Method 1
By means of a photovoltaic module or a plurality of photovoltaic modules, the ambient light, i.e. natural light and/or artificial light, can in a known manner be utilized for generating electrical energy.
Implementation Method 2
An induction coil may be used as a receiver in an electromagnetic energy transmission, so that electrical energy can be fed into the energy-autonomous control element and the induction coil, or a group of induction coils, acts as an energy recovery unit.
Implementation Method 3
a piezoelement or a group of piezoelements could be used as an energy recovery unit. As is well known, a mechanical force exerted on a piezoelement gives rise to an electrical voltage across the piezoelement, so that control operations, which the user of the elevator system carries out by pressing on individual sections of the control element, can be used for generating electrical energy
