Solution Overview

Problem

Pluggable circuit cards and connector sockets in Information Handling Systems (IHS) have limited durability due to excessive insertion cycles, leading to potential memory errors and a lack of tracking mechanisms for card insertion counts, which complicates maintenance and warranty eligibility.

Innovation Solution

Implementing a system with an insertion detector and counter that increments each time a pluggable circuit card is inserted into a socket connector, using mechanical, electrical, or electromechanical sensors, and potentially a dedicated power source like a coin-cell battery to track insertions without requiring external power, allowing for logging and communication of data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If pluggable circuit cards are frequently inserted and removed for upgrades and replacements, then system adaptability and versatility improve, but connector durability and reliability deteriorate due to excessive insertion cycles

Engineering Contradiction:
Improvesystem adaptabilityVSAvoidconnector durability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements preliminary tracking of insertion cycles before the connector reaches its durability limit. The insertion counter monitors each insertion event and provides warnings or alerts when approaching the rated cycle limit, enabling proactive maintenance or replacement before actual failure occurs, thus preserving connector reliability while allowing frequent upgrades

Inventive Principle:
Principle #10Preliminary action

2Ease of manufacture

If the industry reduces plating thickness and uses lower cost materials to reduce connector costs, then manufacturing cost decreases, but connector durability and contact reliability worsen

Engineering Contradiction:
Improvemanufacturing costVSAvoidcontact durability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent implements a feedback mechanism through the insertion counter that monitors usage of cost-reduced connectors. By tracking insertion cycles and providing data on actual wear patterns, the system enables manufacturers to optimize plating thickness and material selection based on real-world performance data, achieving cost reduction without sacrificing reliability

Inventive Principle:
Principle #23Feedback

3Device complexity

If no tracking mechanism is implemented for insertion cycles, then device complexity remains low, but maintenance planning and warranty management become ineffective

Engineering Contradiction:
Improvesystem simplicityVSAvoidmaintenance planning efficiency
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The patent implements preliminary tracking of insertion cycles to enable proactive maintenance planning. The insertion counter records each insertion event and provides advance warning when approaching durability limits, allowing organizations to plan maintenance during scheduled downtime rather than experiencing unexpected failures, thus improving maintenance efficiency without significantly increasing complexity

Inventive Principle:
Principle #10Preliminary action
