Sequencer Mechanism Prevents Connector Damage During Securement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The activation of signal transmitting connections between electronic devices and circuit boards during securement can damage the connections, devices, or boards, highlighting a need for a method to prevent premature activation during assembly.
Innovation Solution
A sequencer mechanism with a bias that inhibits activation of the signal transmitting connection when the electronic device is secured to the circuit board, allowing controlled access to activate the connection only when necessary, thereby preventing damage during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the signal transmitting connection is activated during securement of the electronic device to the circuit board, then the connection can be established early, but damage may occur to the connection, electronic device or circuit board
Solution Approach 1:
The connector portions are aligned and positioned in their final locations before the securement operation is completed. The sequencer mechanism is pre-positioned to block activation during the securement process, ensuring that activation can only occur after proper alignment and securement are achieved.
Solution Approach 2:
The sequencer mechanism acts as an intermediary between the connector portions and the activation mechanism. It physically blocks access to the activation mechanism during securement, preventing premature activation while allowing the securement process to proceed uninterrupted.
2Reliability
If a sequencer mechanism is introduced to control activation sequence, then damage is prevented, but device complexity increases
Solution Approach 1:
The sequencer mechanism is divided into distinct functional components: a body portion that blocks activation, fastener engagement portions that interact with the fasteners, and biasing elements that provide the blocking force. This segmentation allows each component to perform its specific function independently while contributing to the overall simple operation.
Solution Approach 2:
The biasing element automatically provides the blocking force without requiring external control systems or additional actuators. The sequencer mechanism self-regulates the activation sequence through the mechanical interaction between the biasing element, the body portion, and the fastener engagement portions, eliminating the need for complex control circuits or additional power sources.
3Reliability
If the sequencer blocks activation during securement, then connection damage is prevented, but activation access is restricted
Solution Approach 1:
The sequencer mechanism transitions from a blocking state during securement to an non-blocking state after securement is complete. The fastener engagement portions dynamically interact with the fasteners, automatically adjusting the blockage status based on the securement state without requiring manual intervention or complex control systems.
