Solution Overview
Problem
Existing remote controllers for air conditioners and air cleaners require complex operations for setting configurations, and incorporating a large antenna for near field radio communication is challenging due to space constraints, particularly with liquid crystal modules occupying significant space.
Innovation Solution
A remote controller design that includes a casing with a communication surface and a storage component with a shielding part, where the antenna is positioned behind the communication surface with a space between, allowing the coil pattern to overlap the storage component to maximize antenna size and improve communication accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a large antenna is formed to improve communication accuracy, then communication accuracy is improved, but the remote controller size increases due to space requirements
Solution Approach 1:
The patent utilizes the front-rear dimension (depth) of the remote controller by positioning the antenna behind the communication surface with a space between them. This allows the antenna to extend in the depth direction rather than occupying additional lateral space, effectively using three-dimensional space to accommodate a larger antenna area without increasing the overall footprint of the remote controller.
Solution Approach 2:
The antenna is nested within the existing structure of the remote controller by placing it in the space between the communication surface and the internal components (liquid crystal module and shielding part). The coil pattern is arranged to overlap with these existing components in the front-rear direction, effectively nesting the antenna within the available internal volume rather than requiring separate external space.
2Volume of moving object
If the antenna is positioned close to the communication surface to save space, then remote controller size is reduced, but communication accuracy deteriorates
Solution Approach 1:
Rather than increasing lateral distance from the communication surface, the patent exploits the depth dimension by positioning the antenna at an optimized distance behind the communication surface. This allows sufficient separation for magnetic flux passage in the front-rear direction while maintaining compact lateral dimensions.
Solution Approach 2:
The patent creates a localized magnetic flux passing region within the coil pattern that is specifically positioned to avoid the shielding part of the storage component. This ensures that the critical magnetic flux path maintains high quality (unshielded) while other portions of the antenna structure can be positioned to maximize overall antenna area.
3Area of moving object
If the coil pattern overlaps the storage component to maximize antenna size, then antenna area is increased, but magnetic flux may be shielded by the storage component
Solution Approach 1:
The coil pattern is designed with differentiated regions: a magnetic flux passing region that is positioned to avoid the shielding part (maintaining unshielded flux path), and other regions that can overlap the storage component to maximize overall antenna area. This local differentiation allows simultaneous achievement of large antenna size and effective magnetic flux passage.
Solution Approach 2:
The patent converts the potential harmful effect of the shielding part into a beneficial spatial arrangement by designing the coil pattern to overlap the storage component in regions where shielding does not interfere with the magnetic flux passing region. The shielding part's presence actually helps define the optimal positioning of the magnetic flux passing region.
