Removable GPS Module Frame for Clear Locator Signal Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing underground locating systems with integrated GPS capabilities face challenges in receiving accurate signals due to satellite visibility issues and potential interference, and lack flexibility in antenna placement and replacement.
Innovation Solution
A removably attachable GPS module with a frame and antenna arm design that enhances satellite signal reception by positioning the antenna for clear visibility and minimizes interference, allowing for easy installation and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If GPS antenna is integrated into the locator housing, then the system structure is simplified, but satellite signal reception is blocked and interference with locating elements occurs
Solution Approach 1:
The GPS module is separated from the main locator housing into a distinct, removable component. The antenna is positioned on an extendable arm that can be deployed away from the housing, physically segmenting the GPS reception function from the locating elements to prevent signal interference and improve satellite visibility.
2Ease of manufacture
If GPS antenna placement is fixed, then manufacturing is simpler, but adaptability to different job site conditions is reduced
Solution Approach 1:
The GPS antenna is mounted on an extendable arm with adjustable positioning mechanisms, allowing the antenna to be dynamically repositioned to optimal locations for satellite reception based on job site conditions. The entire GPS module can be removed and reattached at different positions, providing adaptability while maintaining straightforward manufacturing of the base unit.
3Reliability
If GPS module is permanently integrated, then connection reliability is improved, but replacement and maintenance become difficult
Solution Approach 1:
The GPS module is designed as a separable component with standardized electrical interfaces that maintain reliable connections during normal operation but allow for easy removal and replacement. The modular design enables the antenna and GPS module to be detached from the locator housing for maintenance or upgrades without damaging the main system.
4Adaptability or versatility
If GPS functionality is included in all units, then complete functionality is provided, but production costs increase for users who don't need GPS
Solution Approach 1:
The locator system is designed with a universal mounting interface and electrical connection standard that can accommodate optional GPS modules. Users who need GPS functionality can attach the module, while those who don't need it can omit the module entirely, allowing the base system to be manufactured at a lower cost while maintaining the capability to add GPS functionality when required.

AI summary
A portable locator includes a locator housing having a display head that supports a display. A GPS module includes a frame and an antenna arm extending from a side margin of the frame. The frame defines a display aperture such that the frame is removably installable on the display head of the portable locator with the display visible through the display aperture. An electrical interface provides for electrical communication with the portable locator with the frame removably installed thereon.
