Solution Overview

Problem

Existing IC sockets with rigid latch members are unable to securely accommodate IC packages of varying thicknesses, requiring a change in latch members for each different thickness, which is inconvenient and inefficient.

Innovation Solution

An IC socket with adjustable latch devices, featuring a latch body and a regulator that allows the lower section to be lifted relative to the upper section, enabling adjustment of the space under the latch to accommodate IC packages of different thicknesses through a screw mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a rigid latch member is used to secure the IC package, then the latching strength is sufficient, but the latch member cannot accommodate IC packages of different thicknesses

Engineering Contradiction:
Improvelatching strengthVSAvoidadaptability to different IC package thicknesses
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The latch member is transformed from a rigid, fixed-structure component into a dynamically adjustable one. The lower section of the latch member can be rotated relative to the upper section around a pivot point, allowing the vertical position of the lower section to be adjusted. This dynamic adjustment enables the latch to accommodate IC packages of varying thicknesses while maintaining secure latching through the pressing action of the lower section against the IC package.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The latch member is divided into two distinct sections: an upper section and a lower section, connected by a pivot point. This segmentation allows independent movement of the lower section relative to the upper section, enabling adjustment of the latching height to match different IC package thicknesses while the upper section remains stable and provides structural support.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the latch member is made adjustable to accommodate different IC package thicknesses, then the versatility is improved, but the device complexity increases

Engineering Contradiction:
Improveadaptability to different IC package thicknessesVSAvoidlatch device complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adjustment mechanism utilizes a simple pivot connection between the upper and lower sections of the latch member, allowing rotational movement without requiring complex mechanisms such as threads, gears, or multiple adjustment components. This keeps the device complexity low while achieving the desired adjustability for different IC package thicknesses.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The adjustable latch member serves multiple functions: it maintains structural support through the upper section, provides adjustable height adaptation through the pivot connection, and delivers secure latching through the pressing action of the lower section. This multi-functionality is achieved within a single integrated component rather than requiring multiple separate adjustment mechanisms.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If multiple latch members are used to cover different IC package thicknesses, then the adaptability is improved, but the device complexity and operation difficulty increase

Engineering Contradiction:
Improveadaptability to different IC package thicknessesVSAvoidease of operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

Instead of requiring multiple separate latch members for different IC package thicknesses, the invention implements a single latch member with adjustable height capability. The pivot connection allows the lower section to be rotated to different vertical positions, enabling one latch member to perform the function previously requiring multiple different-sized latch members, thereby simplifying operation and reducing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The dynamic adjustment capability of the latch member allows operators to quickly adapt the latching height by rotating the lower section around the pivot point, eliminating the need to physically replace latch members when testing IC packages of different thicknesses. This significantly improves ease of operation during testing operations.

Inventive Principle:
Principle #15Dynamics

AI summary

An IC socket for receiving an IC package comprises a socket body for carrying the IC package. A plurality of contacts are received in the socket body for electrical connection with the IC package. A driving member is mounted upon the socket body and able to operate between an upper position and a lower position. At least one latch device comprises an upper section, a lower section parallel to the upper section and a regulator. The regular links the upper section and the lower section and force the lower section to move relative to the upper section.
