Solution Overview

Problem

Conventional semiconductor carriers face issues with semiconductor disengagement due to vibrations and are limited to holding similarly sized components, as larger semiconductors can get stuck and smaller ones may disengage.

Innovation Solution

A stepped elastic positioning structure with L-shaped stop blocks, featuring a stepped surface and elastic deformability, is integrated into the carrier's walls to securely hold and position semiconductors of varying sizes by allowing elastic restriction and easy insertion/removal.

1Reliability

If conventional recesses with upstanding walls are used to hold semiconductors, then semiconductors can be positioned on the bottom of recesses, but slight vibrations may cause disengagement and damage

Engineering Contradiction:

Improvestability of semiconductor positioningVSAvoidvibration-induced disengagement

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The stop block is designed with elastic deformability, allowing it to dynamically adapt to the semiconductor during insertion and then provide elastic restraint during vibration. The stop block can elastically deform to accommodate the semiconductor and then exert elastic force to prevent disengagement, transforming a static structure into a dynamic one that responds to vibrational forces.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The stop block's elastic properties allow it to change its physical state between deformed and restored configurations. When the semiconductor is inserted, the stop block deforms; when the semiconductor is in place, the stop block elastically restores to provide restraint. This parameter change enables the structure to both facilitate insertion and prevent vibration-induced disengagement.

2Adaptability or versatility

If conventional uniform recesses are used, then similarly sized semiconductors can be held, but larger semiconductors get stuck and smaller ones disengage

Engineering Contradiction:

Improvecompatibility with different semiconductor sizesVSAvoiddifficulty of insertion and removal

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The elastic stop block provides a dynamic insertion experience - during insertion, the stop block deforms to accommodate the semiconductor, making insertion easy regardless of size. Once inserted, the stop block elastically restores to provide restraint. This dynamic behavior enables both easy operation and adaptability to different sizes.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The stop block changes its physical configuration from a deformed state during insertion to a restored elastic state during restraint. This parameter change allows the same structure to facilitate easy insertion of various sized semiconductors while providing appropriate restraint forces.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If stop blocks with narrow upper surfaces are used, then small semiconductors can be held, but large semiconductors cannot be properly positioned

Engineering Contradiction:

Improveaccommodation of different semiconductor sizesVSAvoidpositioning accuracy of semiconductor

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The stop block is segmented into two distinct surfaces: a narrow upper surface for positioning small semiconductors and a wider lower surface for positioning larger semiconductors. This segmentation allows each surface to optimize its function for different semiconductor sizes while maintaining precise positioning capability through the elastic restraint mechanism.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different surfaces of the stop block have different local qualities - the upper surface is narrow for precise positioning of small components, while the lower surface is wider for stabilizing larger components. The elastic material property provides uniform local quality of deformability across the entire stop block, enabling adaptive positioning regardless of semiconductor size.

AI summary

A stepped elastic positioning structure for a semiconductor carrier includes a plurality of transversely and longitudinally arranged walls and a plurality of recesses defined by the walls. On the walls of the semiconductor carrier is formed a plurality of L-shaped stop blocks, each of the stop blocks has an elastically deformable free end which is capable of elastically restricting the semiconductor in the recess, and improving the easiness for putting in or taking out the semiconductor. The end of each of the stop blocks is a stepped structure, plus the elastic deformability of the stop blocks, which makes the recess capable of holding different sized semiconductors.
