Tracker Connector Assembly for Repeatable Reattachment Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Navigation systems require recalibration or re-registration of tracking devices when they are removed and reattached to objects, disrupting the positional relationship and affecting tracking accuracy.
Innovation Solution
A connector assembly with a key and receiver mechanism, featuring a preloading mechanism that constrains the key to the receiver with six points of contact, allowing repeatable attachment and detachment without recalibration, using a biasing device to secure the key in the receiver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the tracking device is removed from the object and reattached, then the tracking device can be repositioned or reused, but its positional relationship with respect to the object changes, requiring recalibration or re-registration
Solution Approach 1:
The connector assembly is pre-configured with precisely positioned features (recesses, protrusions, springs) that automatically establish the correct positional relationship between the tracking device and object upon attachment, eliminating the need for recalibration after reattachment
Solution Approach 2:
The connector assembly self-aligns and self-secures the tracking device to the object through its mechanical features (springs, recesses, protrusions), automatically maintaining the positional relationship without requiring external calibration procedures
2Reliability
If the tracking device is firmly attached to the object, then tracking accuracy is maintained, but the attachment mechanism becomes complex requiring multiple components
Solution Approach 1:
Multiple connector components (recess, protrusion, springs, loading surface) are integrated into a single connector assembly that provides both firm attachment and precise positioning in one unified structure, reducing overall system complexity
Solution Approach 2:
The connector assembly serves multiple functions simultaneously: it provides mechanical attachment, precise positioning, and automatic alignment through its integrated features, eliminating the need for separate calibration mechanisms

AI summary
A connector assembly for attaching a tracker body to a tracker support arm. The connector assembly includes a receiver coupled to the tracker body and defining a cavity. The connector assembly includes a key coupled to the tracker support arm and including a loading surface. The key is insertable into the cavity of the receiver. The connector assembly includes a preloading mechanism operably attached to the receiver and including a load member disposed in the receiver. The load member is arranged to contact the loading surface of the key to constrain the key to the receiver, and to thereby attach the tracker body to the tracker support arm.
