Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromagnetic wave reflecting devices struggle to maintain high communication quality in indoor and outdoor environments due to obstructions and the need for wide coverage, especially in Non-Line-Of-Sight (NLOS) sites.
Innovation Solution
The electromagnetic wave reflecting device features a reflection panel that reflects radio waves within a desired frequency band, held by a frame with a conductive portion protected by a non-conductive coating or member, ensuring the edges of the panel are not exposed, thus maintaining reflection efficiency and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the frame is made conductive to improve electromagnetic wave reflection, then reflection efficiency is improved, but rust and corrosion occur reducing reliability
Solution Approach 1:
The frame is constructed as a composite structure combining conductive material (for electromagnetic wave reflection) with non-conductive protective material (for corrosion resistance). The non-conductive protective layer is formed on the surface of the conductive frame, creating a composite material system that simultaneously achieves both reflection efficiency and rust prevention.
Solution Approach 2:
A non-conductive protective layer acts as an intermediary between the conductive frame and the external environment. This protective layer prevents direct contact between the conductive frame and moisture/oxygen, thereby preventing rust while allowing the frame to maintain its electromagnetic wave reflecting function.
2Ease of operation
If the reflection panel edges are exposed to improve installation flexibility, then ease of installation is improved, but undesirable reflections occur reducing communication quality
Solution Approach 1:
The problematic exposed edges of the reflection panel are extracted and integrated into the frame structure. The frame completely surrounds and covers the panel edges, removing the source of undesirable reflections while maintaining the overall installation flexibility of the device.
Solution Approach 2:
The frame and reflection panel are merged into an integrated structure where the frame not only provides mechanical support but also serves to cover and protect the panel edges. This merging eliminates the need for separate edge covering components and ensures complete edge coverage.
3Reliability
If the frame is fully conductive to maximize reflection efficiency, then electromagnetic wave reflection is improved, but manufacturing complexity increases due to protective coating requirements
Solution Approach 1:
The protective coating is applied selectively only to the portions of the frame where corrosion protection is needed, rather than coating the entire frame uniformly. This allows the frame to maintain its conductive properties where needed for reflection while having protective coverage where exposed to environmental factors.
