Card Fixer Hook and Clipping Mechanism for Slot Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Expansion cards with smaller sizes often become loosened, detached, or displaced from slots in laptop computers due to mismatched dimensions, leading to poor contact and operational inefficiencies, especially when external forces are applied.
Innovation Solution
A card fixer with a body and clipping structure, featuring a hook and sliding part, that securely clips and locks the card within the slot, ensuring proper alignment and contact, and includes a sliding mechanism to enhance the card's stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a smaller-sized expansion card is inserted into the slot, then the laptop computer can be more compact and portable, but the card becomes loosened, detached, or displaced due to dimension mismatch
Solution Approach 1:
A card fixer is introduced as an intermediary component between the smaller expansion card and the slot. The card fixer includes a body with a hook that engages with the inside wall of the slot, and a clipping structure that secures the card. This mediator fills the dimensional gap and provides reliable mechanical connection, allowing smaller cards to be used without compromising connection stability.
Solution Approach 2:
The card fixer is divided into distinct functional segments: a body portion that interfaces with the slot, a hook mechanism for wall engagement, and a clipping structure for card securing. This segmentation allows each component to perform its specific function optimally, with the hook providing anchor points and the clipping structure applying localized securing force to the card.
2Ease of operation
If external force is applied to pull or drag the transmission cable, then cable flexibility is maintained, but the expansion card becomes detached from the slot
Solution Approach 1:
The card fixer applies preliminary counteracting force through its hook and clipping structure to prevent card detachment before external forces can cause damage. The hook engages with the slot wall to resist pulling forces, while the clipping structure maintains constant securing pressure on the card, creating preliminary anti-action that counterbalances external cable forces.
Solution Approach 2:
The card fixer structure provides beforehand cushioning by distributing external forces across multiple contact points (hook on slot wall, clipping structure on card edges). This cushioning effect absorbs and dissipates the impact of external pulling forces before they can transmit sufficient force to detach the card from the slot.
3Volume of moving object
If the card dimension does not match the accommodating space of the slot, then smaller cards can be used for compactness, but poor contact between card and slot occurs
Solution Approach 1:
The card fixer body acts as an intermediary that fills the dimensional mismatch gap between smaller cards and the slot. The body provides additional material volume that occupies the unused space, while the hook mechanism provides precise positioning engagement with the slot wall, effectively compensating for the card's smaller dimensions and ensuring proper contact alignment.

AI summary
A card fixer is suitable to assist a card to be fixed in a slot of an electronic device. The card fixer includes a body and a clipping structure, wherein the body has a first side and a second side parallel to the first side. A hook is disposed on the first side of the body. The clipping structure extends out of the second side of the body for clipping the card thereon. When the clipping structure of the card fixer clips the card and the assembly of the card fixer with the card is inserted into the slot, the hook is locked on an inside wall of the slot.
