Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional semiconductor carriers with elastic positioning structures face challenges in maintaining deformability and recoverability of stop blocks, leading to difficulty in inserting and removing semiconductors due to limited deformability and eventual clearance issues that result in loose semiconductor fixation.
Innovation Solution
The semiconductor carrier features a plurality of stop blocks with a narrow top and wide bottom, arranged on the inner surfaces of the walls, forming a tapered structure with specific angles and gaps to facilitate easy insertion and removal while maintaining secure positioning, utilizing an elastic material to ensure deformability and recoverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the upper width of the elastic stop block is made bigger than the lower width to provide push force for fixing semiconductor, then the positioning force is improved, but the deformability is reduced making it difficult to insert and remove semiconductor
Solution Approach 1:
The stop block is divided into distinct sections: an elastic body portion for deformation, an abutting portion for positioning, and a connecting portion for structural integration. This segmentation allows each part to perform its specific function optimally while maintaining overall system performance.
Solution Approach 2:
Different portions of the stop block have different geometric properties tailored to their functions: the elastic body has a narrower width for deformability, while the abutting portion has a wider width for effective semiconductor contact and positioning force application.
2Reliability
If the deformation portion is made elastically deformable with an aperture to improve elasticity, then the recoverability is improved, but the deformability is still limited due to the width difference and push force requirement
Solution Approach 1:
The elastic body portion is designed with a curved cross-section and rounded contours that enhance its elastic deformability. The curved geometry allows greater deflection range compared to a straight or angular design, improving both insertion ease and recovery reliability.
Solution Approach 2:
The elastic body functions as a flexible structural element that can undergo significant deformation. Its geometry and material properties are optimized to provide flexible, reversible deformation for easy semiconductor insertion and removal while maintaining positioning reliability.
3Shape
If the stop block structure is made with non-coplanar deformation and abutting portions, then the positioning structure is formed, but clearance appears after long use leading to loose fixation
Solution Approach 1:
The deformation portion and abutting portion are merged into a single monolithic stop block structure formed from the same elastic material. This integration ensures they remain coplanar and maintain relative positioning over time, preventing clearance formation and ensuring long-term fixation reliability.
Solution Approach 2:
The stop block is formed as an integral structure combining multiple functional portions (elastic body, abutting portion, connecting portion) into a unified elastic component. This composite elastic structure maintains geometric stability and coplanarity throughout its service life, preventing loosening.
4Device complexity
If the stop block is made with uniform width, then the structure is simpler, but it cannot provide sufficient push force for semiconductor fixation
Solution Approach 1:
The stop block employs variable width along its length, with the abutting portion having a larger width than the elastic body portion. This local variation in geometry concentrates the elastic force at the semiconductor contact point, providing sufficient push force for reliable fixation while keeping the overall structure relatively simple.

AI summary
An elastic positioning structure for a semiconductor carrier is provided with a plurality of stop blocks formed on and extending along the walls of the semiconductor carrier, the fixed end and the elastic free end of the respective stop blocks are located at the same level, so that the fixed end can still serve as a restricting structure to restrict the semiconductor, even when the free end of the stop blocks lose elasticity. The positioning structure has a narrow top and wide bottom, and the recess of the semiconductor carrier is narrow at the top and wide at the bottom, so that the semiconductor can be easily taken out and put into the recess, and can be well restricted in recess without disengaging therefrom.
