Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing CPU clips face challenges in securely holding and easily releasing electronic packages, often resulting in damage during disassembly due to a hard securing mechanism.
Innovation Solution
A clip with a frame structure featuring interlinked stopper/kicker and presser mechanisms, a latch, and flexible design elements that allow for vertical retention and easy ejection of the electronic package through a lever operation, enabling secure assembly and convenient disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hard securing mechanism is used to securely hold the electronic package, then the retention reliability is improved, but the clip is prone to damage during disassembly
Solution Approach 1:
The patent applies the dynamics principle by designing a lever-operated ejection mechanism that transforms the static clip structure into a dynamic system. The presser bar, when actuated, leverages the stopper/kicker to dynamically change the retention force direction and magnitude, allowing secure holding during normal operation and easy release during disassembly without damaging the clip.
Solution Approach 2:
The patent segments the retention function into two distinct modes: a securing phase where the latch engages the stopper/kicker for reliable retention, and a releasing phase where the presser bar actuates the ejection mechanism. This segmentation allows the clip to provide strong retention when needed while enabling damage-free removal when required.
2Reliability
If a secure retention mechanism is implemented, then the electronic package is firmly held, but the disassembly process becomes difficult and damaging
Solution Approach 1:
The lever-operated ejection mechanism transforms the static retention system into a dynamic one where a simple pressing motion on the presser bar triggers the stopper/kicker to eject the electronic package. This dynamic action provides firm holding during assembly while enabling convenient, damage-free disassembly.
Solution Approach 2:
The stopper/kicker acts as an intermediary element between the latch and the electronic package. During assembly, it works with the latch to secure the package; during disassembly, it serves as the ejection point when actuated by the presser bar, facilitating easy removal without direct force on the clip structure.
3Device complexity
If a simple clip structure is used, then the device complexity is reduced, but the retention and release functions cannot be achieved simultaneously
Solution Approach 1:
The patent applies universality by designing components that perform multiple functions. The stopper/kicker serves both as a retention anchor when engaged by the latch and as an ejection lever when actuated by the presser bar. The presser bar itself functions as both a structural element and an actuator, reducing the need for separate components while achieving both secure retention and easy release.
Solution Approach 2:
The patent merges the retention and ejection functions into a unified lever-operated mechanism. The latch, stopper/kicker, and presser bar work together as an integrated system where the same structural elements provide both securing and releasing capabilities, eliminating the need for complex separate mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a reliable and secure retention of the electronic package during assembly while allowing for effortless ejection and release during disassembly, minimizing the risk of damage to the clip.
Implementation Method 1
the presser is downwardly pressed and the stopper/kicker is upwardly moved due to a lever operation effect so as to eject the electronic package out of the clip
Implementation Method 2
the latch is optionally deflected to release the electronic package therefrom due to twisting derived from downward movement of the presser

AI summary
A clip for use with an electronic package, includes a frame structure with a pair of first side bars and a pair of second side bars commonly defining a receiving cavity. An ejection device is formed on one first side bar, including a stopper/kicker and a presser interlinked with each other in a co-movement manner. A latch is located around the ejection device so as to cooperate with the stopper/kicker to secure the electronic package therebetween in a vertical direction and retain the electronic package in the receiving cavity to result in an electrical assembly.
