Solution Overview
Problem
Existing methods for installing or removing printed circuit boards in constrained spaces often result in damage due to uneven force application or misalignment, requiring shutdown of systems and disturbing adjacent components, which is unsafe and inefficient.
Innovation Solution
A device comprising a guide plate and a mounting plate connected by a mechanical linkage, allowing for precise vertical movement of the circuit board to align and insert or remove connectors without disturbing adjacent components, using a parallelogram linkage and positioning handle for safe and accurate operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional direct insertion method is used, then the docking process is simple, but the risk of damage due to misalignment and uneven force application increases
Solution Approach 1:
The patent introduces a docking tool as an intermediary device between the operator and the circuit board connector. This tool includes alignment features that guide the connector into proper positioning and distribute insertion forces evenly, preventing damage while maintaining operational simplicity.
Solution Approach 2:
The docking tool performs preliminary alignment of the connector with the receptacle before actual insertion occurs. Alignment marks and guide features are pre-positioned to ensure correct orientation, eliminating misalignment issues during the docking process.
2Productivity
If space-constrained installation is used, then the electronic circuit boards are installed in close proximity, but the ability to accurately dock connectors deteriorates
Solution Approach 1:
The docking tool serves as a mediator that provides external alignment references not available in the constrained space itself. The tool's guide features extend into the limited space and establish precise geometric relationships, enabling accurate docking despite spatial constraints.
Solution Approach 2:
The patent utilizes dimensional extensions of the docking tool that protrude into the constrained space from accessible directions. Alignment marks and guide features are positioned in three-dimensional space to provide reference points that overcome the limitations of two-dimensional planar constraints.
3Productivity
If hot-swapping is performed, then system continuity is maintained, but the risk of damage from manipulating energized components increases
Solution Approach 1:
The docking tool acts as an intermediary that isolates the operator from direct contact with energized components. The tool's structure provides electrical insulation and mechanical protection, allowing safe manipulation of hot-swapped connectors without exposing the operator to electrical hazards.
Solution Approach 2:
The docking tool incorporates protective features that cushion against potential damage during hot-swapping operations. These include force-distributing insertion surfaces and alignment mechanisms that prevent binding or forcing, thereby protecting both the operator and the electronic components from damage.

AI summary
An apparatus to align and dock or undock a first electronic circuit board with a first connector with a second electronic circuit board with a second connector. The apparatus comprises a guide plate with a linkage to connect to a mounting plate. The first electronic circuit board is secured to the mounting plate. The guide plate is inserted into a chassis comprising a guide to receive the guide plate. The guide aligns the first connector to be received in the second connector. The linkage is actuated by displacing a positioning handle. The linkage translates the motion in a direction generally perpendicular to the direction of displacement of the positioning handle. The mounting plate is translated in the generally perpendicular direction, and the first connector is received into the second connector. The operation may be reversed to remove the first connector from the second connector.
