Card Module Side-Loading Layout for FHHL Computing Cards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computing units cannot accommodate Full Height Half Length (FHHL) cards due to their greater dimensions, as they protrude outside the card module chassis, preventing full insertion and operation within the computing unit.
Innovation Solution
A card module with a parallelepipedal chassis design featuring aligned openings and internal connectors on opposite side walls, allowing FHHL cards to be inserted and connected efficiently, with flanges for support and blocking portions for secure retention, enabling simultaneous insertion of two cards while maintaining the same chassis dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the card module chassis is designed with conventional dimensions for standard cards, then standard cards can be properly accommodated and connected, but FHHL cards with greater dimensions cannot be inserted without protruding outside the chassis
Solution Approach 1:
The patent changes the insertion dimension from front-to-back (through the open top face) to side-to-side (through openings in opposite side walls). This dimensional change allows FHHL cards with greater height to be accommodated within the same chassis external dimensions, as the cards are now inserted horizontally rather than vertically, preventing protrusion outside the chassis while maintaining compatibility with larger card formats
2Adaptability or versatility
If cards are inserted vertically through the top face and held by gravity, then the chassis structure remains simple, but FHHL cards protrude outside the chassis and cannot be fully inserted
Solution Approach 1:
The patent transitions from vertical card insertion (top-to-bottom) to horizontal card insertion (side-to-side) by providing openings in opposite side walls. This dimensional change enables FHHL cards to be fully inserted within the chassis boundaries, as the horizontal insertion path accommodates the greater height of FHHL cards without requiring the cards to protrude outside the chassis
3Ease of operation
If the chassis is open on the top face for card insertion, then cards can be easily inserted and connected to internal connectors, but the structural integrity and support for larger FHHL cards are compromised
Solution Approach 1:
The patent replaces the open top face configuration with side wall openings, changing the insertion direction from vertical to horizontal. This modification maintains ease of operation by providing accessible openings while improving structural integrity, as the side wall openings can be properly reinforced and the horizontal insertion path provides better mechanical support for the greater weight and dimensions of FHHL cards

AI summary
The invention relates to a card module configured to be mounted in a computing unit that includes a card module compartment. The card module includes a chassis configured to be mounted in the card module compartment, wherein the chassis includes a parallelepipedal shape, a left side face including a first side wall and a right side face including a second side wall. At least one of the first side wall and the second side wall delimits at least one opening configured to insert a computing card into a slot formed inside the card module. An opposite side wall of the first side wall and the second wall includes an internal connector positioned facing the at least one opening. The internal connector is configured to connect to an external connector of the computing card when the computing card is inserted into the slot up to the opposite side wall.
