Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the distance between two coils is increased to extend transmission range, then energy transmission distance is improved, but electromagnetic radiation increases and efficiency decreases
Solution Approach 1:
The invention segments the transmission system into multiple distributed dipole units rather than using two large coils. Each dipole unit operates at a scale much smaller than the wavelength, preventing significant radiation while collectively achieving extended transmission distance through distributed near-field coupling.
Solution Approach 2:
The invention creates highly localized intense electric fields between each transmitting dipole and its corresponding receiving dipole, confining the energy transfer to specific local regions. This localizes the electromagnetic interaction to near-field zones where coupling is strong but radiation is minimal, even when dipoles are spaced apart.
2Object-generated harmful factors
If electrode size is reduced to minimize radiation, then electromagnetic radiation is reduced, but transmission efficiency decreases due to weaker electric fields
Solution Approach 1:
By segmenting the system into multiple dipole pairs, the invention allows each small electrode to operate independently at optimal near-field coupling distance. The cumulative effect of multiple segmented dipoles achieves high total transmission efficiency while each individual small electrode maintains minimal radiation.
Solution Approach 2:
The invention employs high-frequency oscillating electric fields in the MHz range, creating periodic dynamic coupling between dipoles. This periodic action enables efficient energy transfer through resonant near-field coupling, maintaining strong electric fields despite small electrode dimensions.
3Productivity
If high voltage and high frequency are used to enhance energy transfer, then energy transmission efficiency is improved, but reactive power requirements increase
Solution Approach 1:
The invention distributes the total power transmission across multiple dipole units operating in parallel. Each unit handles a portion of the total power at high voltage and frequency, allowing the reactive power burden to be segmented and managed locally at each dipole pair rather than requiring massive reactive power capacity in a single system.
4Length of stationary object
If the system is scaled up for longer-range transmission, then transmission distance is improved, but electromagnetic radiation and reactive power increase
Solution Approach 1:
The invention scales up the system by adding more segmented dipole units in sequence rather than enlarging individual components. This modular segmentation allows the system to achieve longer transmission distances through cascaded near-field coupling stages, with each stage maintaining small scale to minimize radiation while collectively extending the transmission range.

AI summary
The apparatus according to the invention is composed of one or plural generator devices (2) connected to an energy source and of one or plural loads (3) (which may be mobile). Each load is powered by the intermediary of a limited spatial zone (4) where an electric field that is intense and rapidly varying is present, and this is achieved without wires or electrical contact or use of an earth connection. The intense field is created locally between certain sub-electrodes (5) located on the surface of the generator and an electrode (6) or several sub-electrodes on the load side and located opposite. The active sub-electrodes (5) on the generator side are selected by switches (7), for example magnetic switches activated by a permanent magnet (8) located at the load (3). On the load side, a passive electrode (9) is used which can be considered as mainly coupled to the surrounding dielectric medium. The invention targets, in particular, the tele-supply of energy to low and medium power fixed or mobile electric devices.
