Radio Wave Sensitivity Adjustment via Shielding Disc
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication devices face challenges in accurately transmitting and receiving data while avoiding interference from unintended devices, particularly with Bluetooth technology, due to the long wavelength of radio waves, which requires complex mechanisms and high power consumption for sensitivity adjustment, and is cumbersome for devices like watches that need varying sensitivity settings based on purpose and location.
Innovation Solution
A sensitivity adjustment device with a shielding and penetration mechanism that adjusts radio wave sensitivity by moving a disc-shaped sensitivity adjuster with a rotating shaft, allowing for different communication modes (pairing, data synchronization, and terminal search) by altering the covered area of the antenna, reducing power consumption and maintaining shock resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If sensitivity of the antenna is lowered to avoid interference with unintended electronic devices, then interference avoidance is improved, but communication capability with intended devices at a distance deteriorates
Solution Approach 1:
The patent implements dynamic sensitivity adjustment by moving the sensitivity adjuster (a conductive plate) to different positions relative to the antenna based on communication mode. During pairing mode, the adjuster is positioned to provide shielding and reduce sensitivity to avoid interference. During data transmission mode, the adjuster is repositioned to minimize shielding and maximize sensitivity for reliable communication at a distance. This dynamic reconfiguration allows the system to optimize between interference avoidance and communication capability depending on operational requirements.
2Adaptability or versatility
If sensitivity adjustment mechanism is added to change radio wave sensitivity, then adaptability to different communication modes is improved, but device complexity increases
Solution Approach 1:
The patent changes the physical parameter of antenna sensitivity by adjusting the position of a conductive plate (sensitivity adjuster) relative to the antenna. The adjuster can be positioned at multiple discrete locations: a first position providing shielding for low sensitivity during pairing, and a second position minimizing shielding for high sensitivity during data transmission. This parameter change approach allows the system to achieve multiple communication modes without adding complex electronic control circuits or multiple antennas, thereby improving adaptability while limiting complexity growth.
3Adaptability or versatility
If sensitivity adjustment mechanism is added to adjust radio wave sensitivity, then communication flexibility is improved, but power consumption increases
Solution Approach 1:
The patent replaces electronic sensitivity adjustment mechanisms (which would require active power consumption for amplification or signal processing) with a passive mechanical system. A conductive plate (sensitivity adjuster) is physically moved to different positions using a simple drive mechanism, where it passively shields or exposes the antenna to radio waves. This mechanical substitution eliminates the need for power-intensive electronic sensitivity control circuits, achieving communication flexibility through positional changes rather than active electronic adjustment, thereby significantly reducing power consumption.

AI summary
A sensitivity adjustment device adjusts radio wave sensitivity of an antenna which wirelessly transmits/receives a signal to/from an external device. The sensitivity adjustment device includes: a sensitivity adjuster and an adjuster moving section. The sensitivity adjuster includes (a) a shielding part which shields a radio wave and (b) a penetration part which allows penetration of a radio wave. The adjuster moving section moves the sensitivity adjuster with respect to the antenna in such a way as (a) to change a position of the shielding part and a position of the penetration part with respect to the antenna, and (b) to adjust a covered area of the antenna covered with the sensitivity adjuster, so as to adjust the radio wave sensitivity of the antenna.
