Fixing Frame for OCP Interface Card Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices, particularly those following OCP specifications, lack a release structure for easily removing OCP interface cards, which can lead to damage during removal and render the cards unusable.
Innovation Solution
A fixing frame with a guiding element, a movable element, and a pivotable handle is introduced. The guiding element allows the interface card to be inserted, the movable element facilitates the card's removal by pushing it along a second direction opposite to its insertion, and the handle is designed for easy operation to release the card from the connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If no release structure is provided in the internal space, then the electronic device maintains a compact structure, but the interface card cannot be easily removed and may be damaged during removal
Solution Approach 1:
The release structure is nested within the existing internal space of the electronic device. The guiding element, movable element, and handle are arranged in a compact, space-efficient configuration that integrates with the existing device structure, allowing easy card removal without adding external protrusions or significantly increasing overall device volume.
Solution Approach 2:
The release structure employs dynamic components including a movable element that can shift position and a handle that can rotate between locked and unlocked positions. This dynamic design allows the structure to transform from a compact state during normal operation to an active state during card removal, providing ease of operation while maintaining compactness when not in use.
2Ease of operation
If heat dissipation fins are held by fingers during removal, then the interface card can be grasped, but the interface card may be damaged and the user's finger may be scratched
Solution Approach 1:
The movable element acts as an intermediary between the user's finger and the interface card. Instead of directly grasping the card's heat dissipation fins, the user operates the handle which moves the movable element to push the card along the guiding element. This intermediary mechanism eliminates direct finger contact with potentially sharp edges while still enabling effective card removal.
Solution Approach 2:
The release structure is designed to perform the removal action automatically through mechanical advantage. When the user pivots the handle, the movable element automatically translates this rotational motion into linear pushing motion that ejects the interface card from its seated position, reducing the physical effort and precision required from the user.
3Productivity
If external force is applied to the electrical part of the interface card during removal, then the card can be detached, but the electrical part may be damaged
Solution Approach 1:
The release structure extracts the force application point from the electrical part of the interface card and relocates it to the card's edge or body. The movable element pushes against a non-electrical portion of the card, allowing the card to be ejected without applying stress, bending forces, or direct contact to the electrical connectors or circuitry, thereby preventing damage while maintaining removal efficiency.

AI summary
This disclosure relates to a fixing frame including a guiding element, a movable element, and a handle. The guiding element is configured for an interface card to be placed into the guiding element along a first direction. The movable element is movably disposed in the guiding element. The movable element includes a pushing portion and an abutted portion. The handle is pivotably disposed on the guiding element. The handle includes an abutting portion. The abutting portion selectively abuts the abutted portion of the movable element, so that the pushing portion of the movable element pushes the interface card along a second direction opposite to the first direction.
