Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the coil device is installed at various places (ground surface, outdoor), then it can be used for wireless power transmission and reception, but it is trampled by cars or affected by weather, reducing reliability
Solution Approach 1:
The coil device is divided into a main unit (housing with coil) and a sub-unit (electrical function unit with components), allowing the vulnerable electrical components to be protected within a detachable sub-housing that can be separately maintained or replaced without affecting the entire device
2Productivity
If the coil device is installed in harsh environments, then it can perform wireless power supply functions, but maintenance work is required frequently, reducing ease of maintenance
Solution Approach 1:
The device is segmented into main unit and sub-unit, where the sub-unit containing electrical components can be detached and replaced independently, significantly easing maintenance operations in field conditions
Solution Approach 2:
The electrical function unit is extracted into a separate detachable sub-housing, allowing maintenance personnel to access and replace components without opening the main housing or disrupting the coil structure
3Device complexity
If all components are integrated in one housing, then the device structure is simple, but replacement of electrical components requires opening the main housing, increasing maintenance time
Solution Approach 1:
The device is divided into main unit and sub-unit with detachable connection, creating a modular structure that balances structural simplicity with rapid maintenance capability
Solution Approach 2:
The sub-unit is pre-configured as a detachable module, allowing electrical components to be replaced by simply detaching the sub-housing without requiring disassembly of the main housing structure
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
Facilitates easy maintenance of coil devices by allowing separate replacement of electrical components, while reducing electromagnetic interference and enhancing durability.
Implementation Method 1
When AC power is provided to a coil provided in a power transmission-side device, as a result, an electromagnetic field is generated around the coil
Implementation Method 2
When the electromagnetic field reaches a power reception-side device, as a result, an induced electric current is generated in a power reception-side coil

AI summary
A coil device includes a main unit in which a coil that wirelessly transmits or receives electric power is accommodated in a main housing fixed to an installation target, and a sub-unit in which an electrical function unit that provides the main unit with an electrical function performed by at least one of an electric component and an electronic component is accommodated in a sub-housing detachably configured to be attached to the main housing. The main unit includes an accommodation portion that detachably accommodates the sub-unit.
