Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Meter assemblies in rural areas face limited communication capabilities due to the restricted size of internal antennae, which affects their connectivity with other nodes in the network.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the antenna is retained inside the meter with size restrictions, then the meter structure is compact and simple, but the antenna gain is limited and communication capability is reduced
Solution Approach 1:
The antenna system is divided into two independent parts: an internal meter antenna housed within the meter for basic functionality, and an external modular antenna assembly that can be attached to the meter collar for enhanced communication capability. This segmentation allows each antenna to be optimized independently while maintaining overall system compactness.
Solution Approach 2:
The solution transitions from a single-dimension internal antenna constraint to a multi-dimension system by adding an external antenna assembly that extends beyond the meter boundaries. The modular antenna can be positioned in three-dimensional space around the meter, utilizing vertical and radial dimensions to achieve superior gain without increasing the meter's internal volume.
2Device complexity
If a fixed internal antenna is used, then the device structure is simple, but the adaptability to different communication environments is limited
Solution Approach 1:
The antenna system transitions from a static internal antenna to a dynamic configuration where the modular external antenna can be attached, detached, or repositioned as needed. The adjustable dial mechanism enables dynamic orientation changes of the directional antenna to adapt to varying communication environments and node positions.
Solution Approach 2:
The meter collar is designed with a universal connector that can accommodate different types of modular antenna assemblies. The system supports both omnidirectional and directional antenna configurations, allowing the same meter infrastructure to serve multiple communication scenarios from rural areas with few nodes to urban areas with many nodes.
3Reliability
If the antenna assembly is made adjustable for optimal positioning, then communication directivity is improved, but the device complexity increases
Solution Approach 1:
The adjustable dial mechanism provides dynamic positioning capability for the modular antenna, allowing operators to rotate and orient the antenna in different directions to achieve optimal communication directivity. The dial can be manually adjusted and locked into position, creating a simple yet effective dynamic adjustment system.
Solution Approach 2:
The adjustable dial with position indicator replicates the functionality of complex electronic steering mechanisms through a simple mechanical interface. The dial provides tactile feedback and visual position indication, creating a user-friendly control system that mimics more sophisticated adjustment mechanisms without their complexity.
4Reliability
If the antenna is vertically offset from the meter, then the radiation pattern is optimized and connectivity is improved, but the mounting structure becomes more complex
Solution Approach 1:
The modular antenna assembly is positioned in a vertical dimension offset from the meter body, extending upward from the meter collar. This vertical displacement creates optimal radiation patterns by separating the antenna from potential interference sources in the meter housing while maintaining a compact overall structure through the collar mounting interface.

AI summary
A meter assembly includes an meter, a meter collar, and a modular antenna assembly. The meter includes a meter antenna housed within the meter. The meter collar is coupled to the meter and includes a collar connector electrically coupled to the meter antenna through a coaxial cable. The modular antenna assembly includes a modular antenna and a modular antenna connector. In some cases, the modular antenna assembly is detachably mounted to the meter collar, and the modular antenna connector is configured to detachably connect with the collar connector such that the modular antenna is electrically coupled with the meter antenna. In various examples, a gain of the modular antenna is higher than a gain of the meter antenna.
