Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable video apparatuses often lack 4G communication capabilities and internal storage space for 4G transmission, leading to restricted functionality and failure in instant image transmission, particularly in areas with imperfect WiFi coverage, which affects evidence collection and enforcement of policies.
Innovation Solution
A wireless transmission expansion device with an expansion unit, a wireless transmission device, and an antenna module that connects via positioning clamping arms, allowing for 4G transmission without occupying internal space and interfering with the video apparatus's intrinsic functions, ensuring compatibility and cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If portable video apparatuses use internal storage for video information, then storage capacity is limited, but adding 4G transmission capability requires additional internal space which is not available
Solution Approach 1:
The invention divides the transmission functionality into separate external modules (4G transmission module, WiFi transmission module) that can be independently attached to the video apparatus. This segmentation allows the video apparatus to gain 4G capability without requiring internal space, as the transmission modules are housed in external expansion devices that attach to the device's exterior interface.
2Productivity
If portable video apparatuses are equipped with 4G transmission modules internally, then instant transmission capability is improved, but device complexity and cost increase
Solution Approach 1:
The expansion device incorporates multiple transmission modules (4G and WiFi) within a single external unit that can serve multiple video apparatuses. The device includes a control unit that can switch between different transmission modes, providing universal functionality across different scenarios without requiring each video apparatus to have dedicated internal modules for each transmission type.
Solution Approach 2:
The transmission modules are nested within the expansion device housing, with the 4G transmission module and WiFi transmission module contained within the same external structure. This nesting approach consolidates multiple functions into a single attachable unit, reducing overall system complexity compared to having separate internal modules for each transmission type.
3Reliability
If existing video apparatuses are modified to support 4G transmission, then communication capability is improved, but compatibility with existing devices is reduced
Solution Approach 1:
The invention extracts the 4G transmission functionality from the video apparatus itself and places it in an external expansion device that attaches to the video apparatus via a standard interface. This extraction allows the video apparatus to maintain its original design and compatibility, while the external module provides the additional 4G capability when needed.

AI summary
A wireless transmission expansion device includes: an expansion unit having a bottom base portion, the bottom base portion having therein a receiving space, wherein each of two sides of the bottom base portion extends to form a positioning clamping arm, and the two positioning clamping arms define therebetween a clamping space; a wireless transmission device disposed in the receiving space; and at least one antenna module disposed at the positioning clamping arms and being in signal connection with the wireless transmission device. Therefore, the wireless transmission expansion device operates in conjunction with an existing video apparatus or portable camera not capable of 4G transmission or not having internal storage space required for 4G transmission, so as to instantly transmit a large amount of video information.
