Detachable Multi-Leg Utility Locator Stand for Upright Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing utility locator devices require user support and are often bulky or intrusive, limiting their use in self-standing configurations, especially in traditional line locate operations, and are not compatible with utility locators having round masts.
Innovation Solution
A self-standing attachment device with detachable legs that can be easily secured to a utility locator, allowing it to stand upright without user support, and is stowable for transportation, using non-ferromagnetic materials to minimize signal interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If utility locator devices are configured to self-stand in an upright position, then user burden is reduced and the locator can operate independently, but the device becomes bulky and intrusive, preventing safe carrying out of tasks
Solution Approach 1:
The self-standing attachment device is divided into separate legs that can be detached and stored when not in use. The legs attach to the utility locator when needed for stationary operation, but can be removed to eliminate bulk during mobile locate operations, resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
The attachment device transitions from a static, permanently fixed structure to a dynamic, deployable structure. The legs can be extended when stationary support is needed and retracted or removed when mobility is required, allowing the device to adapt its form factor to operational needs.
2Stability of the object's composition
If permanently fixed self-standing mechanisms are used, then the locator can stand upright without user support, but the mechanisms are bulky and intrusive
Solution Approach 1:
The permanently fixed self-standing mechanism is segmented into detachable legs that can be separated from the main body. This allows the stability function to be activated only when needed, eliminating the permanent bulk and intrusiveness while maintaining self-standing capability during stationary operations.
Solution Approach 2:
The legs are designed to be discarded (removed) from the utility locator when mobile operation is needed, and recovered (reattached) when stationary self-standing operation is required. This temporary attachment approach eliminates permanent bulk while maintaining functionality when needed.
3Duration of action of stationary object
If self-standing devices with fixed mechanisms are used, then the locator can maintain upright position, but the mechanisms prevent safe carrying out of tasks
Solution Approach 1:
The fixed self-standing mechanism is segmented into removable legs, allowing the utility locator to transition between stationary and mobile modes. When legs are attached, long-duration stationary operation is enabled; when removed, safe mobile operation is restored, resolving the contradiction between operation duration and task safety.
4Reliability
If self-standing attachment devices are designed for non-round masts, then they can secure to specific locator types, but they cannot be used with utility locators having round masts
Solution Approach 1:
The attachment device is designed with a universal mounting mechanism that can accommodate both round and non-round masts. The mounting interface is configured to provide secure attachment across different mast geometries, enabling a single device design to serve multiple locator types without compromising attachment reliability.

AI summary
Self-standing attachment devices for use with utility locator systems are disclosed. In one embodiment a self-standing attachment device includes a top assembly, three extendable legs coupled to the top assembly with a movable joint, and a bottom assembly, with the self-standing attachment device detachably coupleable to a locator of the system. A formed coupler in the top assembly allows for readily attaching and detaching the self-standing attachment device and the locator.
