Lantern Radio Antenna Layout for Impact Protection and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a device that combines the functions of a lantern and an audio output system, capable of illuminating surroundings and providing sound output, particularly in outdoor or disaster scenarios, while ensuring stability and reducing the risk of external impact.
Innovation Solution
The audio output device incorporates a lantern part, an antenna part, and an audio output part, with the antenna part also serving as a protective element, and a control unit that manages light and sound output. The device is designed with a battery pack mounting system for stability and includes features like a flashlight for directed illumination and a USB terminal for external device charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the antenna part is positioned close to the lantern part for compact design, then device complexity is reduced, but the lantern part becomes vulnerable to external impact
Solution Approach 1:
The antenna part is designed to serve dual functions: receiving radio broadcasting waves and protecting the lantern part from external impact. This multi-functionality resolves the contradiction by eliminating the need for separate protection structures, thereby reducing device complexity while maintaining protective capability.
Solution Approach 2:
A space is intentionally provided between the antenna part and the lantern part, acting as a buffer zone that absorbs external impacts before they reach the lantern part. This intermediary space allows the antenna to extend outward for better signal reception while simultaneously serving as a protective barrier.
2Device complexity
If the battery pack is positioned at the top for compact design, then device complexity is reduced, but stability deteriorates
Solution Approach 1:
The battery pack, being the heaviest component, is positioned at the bottom of the device to act as a counterweight that lowers the center of gravity. This positioning improves overall device stability and prevents tipping, especially when the lantern part is extended outward for illumination.
3Device complexity
If the audio output part is positioned below the lantern part for compact design, then device complexity is reduced, but sound propagation is hindered
Solution Approach 1:
The audio output part is positioned at the top of the device, utilizing the vertical dimension for sound propagation. This arrangement allows sound waves to travel upward and outward without being blocked by the lantern part, resolving the contradiction between compact design and effective sound propagation.

AI summary
An audio output device has a lantern part extends along a first axis, an antenna part, an audio output part, and a control part. The antenna part has a first end and a second end that are respectively connected to a first side and a second side relative to a central part of the lantern part in a first direction parallel to the first axis. A portion of the antenna part between the first end and the second end extends in the first direction and is spaced apart from the lantern part in a direction orthogonal to the first direction. The control part is configured to cause the audio output part to output sound corresponding to a radio broadcasting wave received by the antenna part.
