Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with antenna structures facing the rear surface encounter difficulties in efficient disposition due to interference with peripheral components, limiting the formation of directional signals in desired directions.
Innovation Solution
The electronic device incorporates a conductive structure within its housing, allowing the antenna structure to be disposed such that its substrate surfaces face different directions. This configuration utilizes diffraction and reflection of the directional signal by the conductive structure to change the signal direction, enabling efficient disposition and enhanced beam coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna structure is disposed with substrate surface facing the rear surface of the electronic device, then the directional signal can be formed towards the rear surface, but it is difficult to secure a disposition structure due to interference with peripheral components
Solution Approach 1:
A reflector structure is introduced as an intermediary component between the antenna and the rear surface. The reflector receives signals from the antenna and redirects them towards the rear surface, enabling directional signal formation without requiring the antenna substrate to face the rear surface directly. This resolves the conflict by decoupling the antenna orientation from the signal direction.
Solution Approach 2:
Instead of orienting the antenna substrate surface towards the rear surface to form directional signals, the invention inverts the approach by orienting the substrate surface towards the front surface and using a reflector to redirect signals backwards. This inversion allows the antenna to be disposed in a manner that avoids interference with peripheral components while still achieving rear-surface signal formation.
2Reliability
If the antenna structure is disposed with substrate surface facing the rear surface, then the directional signal can be formed in the desired direction, but the disposition space is increased due to interference with peripheral components
Solution Approach 1:
The reflector acts as a mediator that enables signal redirection in a compact configuration. By placing the reflector adjacent to the antenna rather than requiring the antenna to extend towards the rear surface, the overall disposition space is reduced while maintaining the ability to form directional signals towards the rear surface.
Solution Approach 2:
The invention changes the spatial dimension of signal propagation by using the reflector to redirect signals at an angle. Instead of the antenna directly facing the rear surface (one-dimensional alignment), the signal path is bent through the reflector, utilizing angular redirection to achieve the same effective signal direction with reduced linear space requirements.
