Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computing systems face challenges in efficiently and flexibly installing and managing multiple pluggable modules within system boards, particularly in terms of space constraints and the need for secure, accessible, and easily removable configurations.
Innovation Solution
The implementation of a module cage system with guide channels, leadscrew mechanisms, and locking handles allows for the installation and secure positioning of pluggable modules in multi-row bays, enabling flexible placement and removal without requiring the removal of pre-installed modules, using carrier brackets and elevator systems for mechanical and blind-mate coupling.

Engineering Contradiction Analysis
1Area of stationary object
If multiple pluggable modules are installed in a compact multi-row bay configuration, then space utilization is improved, but accessibility and ease of installation/removal deteriorate due to space constraints
Solution Approach 1:
The module cage is segmented into multiple independent multi-row bays, each with its own loading arm and carrier assembly. This segmentation allows individual modules in different rows to be accessed and operated independently, resolving the contradiction by maintaining space efficiency while enabling selective access without disrupting other modules.
Solution Approach 2:
A loading arm with carrier bracket assembly acts as an intermediary mechanism between the operator and the pluggable modules. The loading arm provides mechanical leverage and precise positioning, while the carrier bracket holds the module during insertion, making installation and removal easier despite the compact multi-row configuration.
2Reliability
If pluggable modules are securely locked in place, then reliability of connection is improved, but ease of removal and reconfiguration deteriorates
Solution Approach 1:
The locking mechanism is designed to be dynamic rather than static - the carrier bracket can be in a locked position during operation for reliability, but can be easily released when removal is needed. The loading arm mechanism provides controlled force to secure modules during normal operation while allowing deliberate release for reconfiguration.
Solution Approach 2:
The module and receptacle incorporate self-aligning features with guide channels and alignment pins that automatically position the module correctly during insertion. This self-service alignment ensures reliable connection without requiring complex manual positioning, and the same features facilitate easy removal by maintaining precise alignment during the extraction process.
3Productivity
If automated loading mechanisms are implemented, then productivity of module installation is improved, but device complexity increases
Solution Approach 1:
The automated loading system is segmented into independent loading arms, each with its own motor and carrier bracket assembly. This modular segmentation allows the system to achieve automated productivity without requiring a single complex centralized mechanism, as each loading arm can operate independently with relatively simple individual components.
Solution Approach 2:
The loading arm and carrier bracket assembly are designed as universal components that can handle multiple types of pluggable modules. The same basic mechanism structure serves multiple functions: holding the module, guiding it into position, securing it during operation, and enabling removal. This multi-functionality reduces overall system complexity while maintaining automated productivity.
