Existing stacking containers lack an efficient method for wireless energy transfer between stacked elements, requiring conversion of voltage or current, which complicates the design and reduces energy transfer efficiency.
Innovation Solution
The implementation of a resonant inductive coupling system with coils connected in series or parallel, along with a capacitor to form an oscillating circuit, allows for contactless energy transfer between stack elements without the need for inverters or rectifiers, using a communication interface for data transmission, and a power generation device to adjust energy supply based on consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If voltage or current conversion is implemented in stacking containers, then energy transfer between stacked elements is enabled, but device complexity increases due to inverters or rectifiers
Solution Approach 1:
The patent removes the voltage conversion components (inverters or rectifiers) from the stacking container system entirely. Instead of converting voltage levels within each container, the system uses direct inductive coupling between coils at the same voltage level (48V), extracting the unnecessary conversion stage while maintaining energy transfer capability.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary for energy transfer. The transmitting coil generates a magnetic field that couples with the receiving coil, enabling wireless energy transfer without direct electrical contact or voltage conversion. This magnetic field mediator allows efficient energy transfer while avoiding complex conversion circuitry.
2Ease of operation
If inductive coupling is used for wireless energy transfer, then contactless energy transfer is achieved, but energy loss increases without resonant frequency matching
Solution Approach 1:
The patent applies resonant oscillation at a specific frequency (e.g., 6.78 MHz according to the OET standard mentioned) to the inductive coupling system. By tuning both transmitting and receiving coils to the same resonant frequency, the system achieves enhanced energy transfer efficiency and reduced losses through constructive interference of the magnetic fields.
Solution Approach 2:
The patent optimizes key parameters including coil geometry, winding density, core material properties, and operating frequency to achieve maximum coupling efficiency. By carefully selecting and adjusting these parameters, the system minimizes energy loss while maintaining contactless operation.
