Communication Adapter Antenna Placement for Wireless Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric working machine systems face challenges with stable attachment and detachment of communication adapters, as well as compromised wireless communication quality due to obstruction by the machine body and battery pack.
Innovation Solution
The communication adapter is designed with an antenna on a surface not facing the recess, and an interface device on a different surface, allowing for stable attachment, easy detachability, and improved wireless communication performance. Additionally, a contactless power supply system and elastic members enhance reliability and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the adapter is held between the electric power tool body and the battery pack, then stable attachment is achieved, but good usability cannot be achieved due to troublesome attachment and detachment actions
Solution Approach 1:
The adapter is separated into a独立 detachable unit that interfaces with both the power tool body and battery pack, allowing it to be attached or detached as a single component rather than requiring complex assembly actions
Solution Approach 2:
The adapter serves as an intermediary device positioned between the power tool body and battery pack, providing wireless communication functionality while maintaining a simple attachment interface that improves usability
2Stability of the object's composition
If the adapter is held between the electric power tool body and the battery pack, then stable attachment is possible, but good attachability and detachability cannot be achieved
Solution Approach 1:
The adapter is designed as a separate modular component with simplified attachment structures that enable easy attachment and detachment operations while maintaining stable connection when mounted
3Stability of the object's composition
If the adapter is held between the electric power tool body and the battery pack, then stable attachment is achieved, but radio wave transmission may be obstructed, resulting in adverse influence on wireless communication quality
Solution Approach 1:
The antenna is positioned at a specific location on the adapter where it can transmit and receive radio waves effectively without being blocked by the power tool body or battery pack, optimizing wireless communication performance at that local position
Solution Approach 2:
The antenna is arranged at an outer surface of the adapter that does not face the power tool body, utilizing a different spatial dimension or orientation to avoid radio wave obstruction and improve wireless communication quality
