Adjustable Metal Detector Shaft for Ergonomics and Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing metal detectors lack ergonomic adjustability and efficient storage/transport solutions, as they often require fixed configurations that do not accommodate user preferences or reduce in size effectively.
Innovation Solution
A handheld metal detector body with an adjustable grip element and armrest system, allowing for telescopic extension and locking mechanisms to change between S-rod and straight rod configurations, enabling customizable ergonomics and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed configuration body is used, then the structure is simple, but the ergonomic adjustability is poor
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed body structure into an adjustable one. The grip element and armrest are made movable relative to each other through a telescopic mechanism with locking positions, allowing the body to adapt to different user preferences and operational requirements while maintaining structural integrity.
Solution Approach 2:
The body is segmented into distinct movable components: the grip element, the armrest, and the connecting shaft element. This segmentation allows independent adjustment of each component's position, providing ergonomic flexibility without requiring complete redesign of the entire body structure.
2Length of moving object
If the body is designed for extended use with fixed ergonomics, then user comfort is maintained for specific users, but the product cannot be reduced in size for storage and transport
Solution Approach 1:
The patent implements the nesting principle by allowing the grip element to telescope within the shaft element, and the armrest to fold or retract. This enables the body to be collapsed into a compact configuration for storage and transport, while maintaining full extendability and adjustability during operational use.
3Adaptability or versatility
If the distance between armrest and grip element is fixed, then the manufacturing is simpler, but the adaptability to different operators is limited
Solution Approach 1:
The locking mechanism is designed to be self-servicing, allowing users to easily adjust and lock the grip element and armrest at their preferred positions without requiring tools or complex procedures. The mechanism provides inherent stability at locked positions while remaining simple to operate.

AI summary
A body for a handheld metal detector includes a lower end configured to engage with a sensor head; an upper end including an armrest connected to an upper shaft element; and a grip element intermediate to the lower end and the upper end, the grip element including a grip portion configured to allow a user to hold the body, and a first retaining means for slidably retaining the upper shaft element such that the distance between the armrest and the grip element is able to be adjusted.
