Fiber Tray Pivot Interlock With Detent Position Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber optic tray systems lack a robust and reliable mechanism for securely holding fiber management trays at desired pivot positions, complicating access and management within telecommunications enclosures.
Innovation Solution
A pivot interlock system with integrated detent and guide pivot arrangements allows the fiber management trays to pivot smoothly between positions, utilizing detent pivot pins and receptacles for retention, and cylindrical pivot pins and guide receptacles for guided movement, providing a stable pivot axis and retention force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pivot mechanism is used to allow tray movement between positions, then accessibility is improved, but reliability of maintaining position deteriorates
Solution Approach 1:
The pivot mechanism is divided into two functional segments: a guide pivot arrangement for enabling smooth movement between positions, and a detent pivot arrangement for maintaining stable positions. This segmentation allows each component to specialize in one function, resolving the contradiction between movement capability and position stability.
Solution Approach 2:
The detent receptacle acts as an intermediary element between the detent pivot pin and the tray body. It provides the elastic deformation necessary to engage and disengage the detent pin from the receptacle, enabling reliable position maintenance while allowing controlled movement when needed.
2Reliability
If a detent arrangement is added to hold tray at desired position, then position stability is improved, but device complexity increases
Solution Approach 1:
The detent pivot arrangement and guide pivot arrangement are merged into a single integrated pivot interlock mechanism. Both arrangements share common components such as the pivot pin and receptacle structures, eliminating the need for separate mechanisms and reducing overall device complexity while maintaining position stability.
Solution Approach 2:
The pivot interlock mechanism serves multiple functions simultaneously: it guides the tray movement, provides detent positioning, and maintains structural connection between the tray and mount. This multi-functionality reduces the need for additional separate components, thereby reducing device complexity.
3Adaptability or versatility
If multiple pivot positions are implemented, then adaptability is improved, but ease of operation deteriorates
Solution Approach 1:
The detent pivot pin engages with the detent receptacle in a periodic manner as the tray pivots, creating distinct engagement points at each desired position. This periodic engagement provides clear tactile feedback and automatic positioning, making the operation simple despite having multiple position options.
