Solution Overview
Problem
Autonomous moving apparatuses face accuracy issues in estimating direction and angle due to disturbance noises from similar radio waves, leading to deteriorated movement control accuracy.

Incorporation of radio wave prevention units that block or absorb radio waves from predetermined directions, using materials like ferrite and carbon-based absorbers or metal shields, to reduce interference and enhance directional reception accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If radio wave receiving units are used to estimate direction and angle, then autonomous movement capability is enabled, but disturbance noises from similar radio waves cause accuracy deterioration
Solution Approach 1:
The patent introduces radio wave prevention units as intermediary components between the radio wave receiving units and the external environment. These units selectively block or absorb interfering radio waves from specific directions while allowing desired radio waves to pass through, thereby mediating the interaction between the receiving units and the complex radio wave environment to improve measurement precision without sacrificing autonomous movement capability
Solution Approach 2:
The patent applies local quality by making different parts of the apparatus have different radio wave properties. The radio wave prevention units are positioned and oriented to have specific absorption or blocking characteristics for radio waves from particular directions, while the radio wave receiving units have directional sensitivity optimized for receiving signals from specific sources. This local differentiation allows the system to distinguish between desired and unwanted radio waves
2Measurement precision
If radio wave prevention units are added to block disturbance noises, then directional reception accuracy is improved, but device complexity increases
Solution Approach 1:
The radio wave prevention units are designed to serve multiple functions: they block or absorb interfering radio waves from specific directions, and simultaneously serve as structural components of the apparatus housing or mounting structure. This multi-functionality allows the system to improve directional reception accuracy without proportionally increasing device complexity, as the prevention units integrate with existing structural elements rather than adding entirely separate components

AI summary
An autonomous moving apparatus is an apparatus that autonomously moves toward a target object set in advance, and includes a plurality of radio wave receiving units that receive a radio wave transmitted from the autonomous moving apparatus or an external device, a radio wave prevention unit that blocks or absorbs a radio wave from a predetermined direction when viewed from the radio wave receiving units, a movement direction setting unit that sets a movement direction of the autonomous moving apparatus based on a measurement result by the plurality of radio wave receiving units, and an operation control unit that controls the autonomous moving apparatus to travel in the movement direction set by the movement direction setting unit.
