Segmented Contact Block for Semiconductor Device Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connecting apparatuses for semiconductor devices, such as integrated circuits, face difficulties in correctly positioning and exchanging contact pieces due to independent contact pieces and the need to separate components, leading to cumbersome operations during maintenance.
Innovation Solution
A contact block design featuring paired contact pieces with U- or V-shaped intermediate regions and arm portions, where the folded end portions are buried in an electrically insulated combining block, allowing for easier assembly and disassembly by exchanging the contact blocks as a unit, facilitating the positioning of tips for common contact with conductive portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If contact pieces are made independent for flexibility, then adaptability is improved, but device complexity and ease of operation deteriorate due to difficulty in positioning and exchanging contacts
Solution Approach 1:
The contact structure is divided into two functional parts: the contact piece (with arm portions and tip regions) that can be exchanged, and the combining block that remains fixed. This segmentation allows the contact pieces to be independently replaced while maintaining their precise relative positioning through the combining block, thus providing flexibility without compromising ease of operation.
Solution Approach 2:
The combining block serves as an intermediary component that holds and positions multiple contact pieces. By burying the folded end portions of contact pieces in the combining block, it acts as a mediator that maintains the spatial relationship between contact pieces, enabling easy exchange of individual contact pieces while preserving the overall contact configuration.

3Ease of repair
If cover and base plate are separated for contact exchange, then ease of repair is improved, but productivity deteriorates due to contact loss and reassembly complexity
Solution Approach 1:
The contact assembly is segmented into the contact block (containing contact pieces) and the cover-base plate assembly. This allows the contact block to be exchanged independently without separating the cover from the base plate, maintaining ease of repair while improving productivity by preventing contact loss and simplifying reassembly.
Solution Approach 2:
The contact pieces are merged with the combining block to form an integrated contact block assembly. This merging allows the entire contact block to be exchanged as a single unit, eliminating the need to handle individual contact pieces separately, thus improving productivity while maintaining ease of repair.
4Reliability
If contact pieces are repositioned after falling off, then reliability is improved, but loss of time increases due to manual rearrangement
Solution Approach 1:
The contact structure is divided into two functional parts: the contact piece (with arm portions and tip regions) that can be exchanged, and the combining block that remains fixed. This segmentation allows the contact pieces to be independently replaced while maintaining their precise relative positioning through the combining block, thus providing flexibility without compromising ease of operation.

By burying the folded end portions of contact pieces in the combining block, it acts as a mediator that maintains the spatial relationship between contact pieces, enabling easy exchange of individual contact pieces while preserving the overall contact configuration.

AI summary
A contact block includes a contact having a pair of contact pieces spaced apart, and an electrically insulating combining block for combining the contact pieces. Each contact piece is provided with a horizontal U-shaped or a horizontal V-shaped intermediate region having a folded end portion and a pair of arm portions vertically spaced apart from the folded end portion; a first tip region extending downward from the tip portion of one of the arm portions; and a second tip region extending upward from the tip portion of the other arm portion. The folded end portions of both contact pieces are buried within the combining block and the remaining parts of both contact pieces are projected from the combining block. Thereby, in a state of being assembled into the electrical connecting apparatus, adjoining contacts are positioned by the combining block, and contacts can be exchanged by exchanging contact blocks.
