Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical contacts with inner contacting arms that extend in the same direction as outer contacting arms hinder miniaturization due to increased space requirements and rigidity issues, making it difficult to achieve proper coupling between the arms.
Innovation Solution
An electrical contact design featuring a retention section and an extension section linked by a transverse bridge, with upper and lower contacting arms and abutment tabs that minimize dimension and provide resiliency for effective coupling between the CPU and PCB, allowing for a shorter inner contacting arm while maintaining flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the inner contacting arm extends along the same direction as the outer contacting arm, then the coupling between the arms is simplified, but the space requirement increases and miniaturization is hindered
Solution Approach 1:
The inner contacting arm is repositioned from extending in the same direction as the outer contacting arm to extending in a transverse direction, utilizing a different spatial dimension. This dimensional change allows the inner arm to be shorter while still achieving proper coupling, thereby reducing overall space requirements and enabling miniaturization without sacrificing coupling effectiveness
2Volume of moving object
If the inner contacting arm is shortened for miniaturization, then the space requirement is reduced, but the resiliency and coupling capability of the arm deteriorates
Solution Approach 1:
By changing the extension direction of the inner contacting arm to a transverse orientation perpendicular to the outer contacting arm, the patent achieves two objectives simultaneously: the arm can be shortened for miniaturization while the transverse configuration provides adequate resiliency and coupling capability through geometric leverage and structural arrangement
Solution Approach 2:
The patent modifies the geometric parameters of the inner contacting arm by changing its extension direction and positioning, which alters the mechanical properties and resiliency characteristics. This parameter change allows a shorter arm length to maintain or even enhance coupling performance compared to a longer arm in a different configuration
3Stability of the object's composition
If the inner contacting arm is made rigid for structural stability, then the structural integrity is improved, but the coupling flexibility and adaptability during operation is reduced
Solution Approach 1:
The transverse extension of the inner contacting arm creates a geometric configuration that inherently provides flexibility and adaptability. The perpendicular arrangement allows the inner arm to deflect and adjust during coupling operations, maintaining coupling flexibility while the overall structure retains structural integrity through the bridge connection
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 design achieves miniaturization of the contact structure while ensuring proper mechanical and electrical coupling between the CPU and PCB, with the transverse bridge providing additional resiliency to the inner part, enabling smooth and guided coupling.
Implementation Method 1
Because the bridge may provide the inner part with more resiliency, the coupling between the abutment tip region of the outer part and the abutment tab of the inner part may be properly implemented

AI summary
An electrical contact includes a retention section of an outer part and an extension section of an inner part parallel to each other and linked to each other via a transverse bridge located in another vertical plane perpendicular to both the retention section and the extension section. An upper contacting arm extends, toward the extension section, from an upper end of the retention section with an upper mating apex and an upper abutment tip region, and a lower contacting arm extends, toward the extension, from a lower end of the retention section with a lower mating apex and a lower abutment tip region. An upper abutment tab upwardly and obliquely extends from an upper end of the extension section toward the retention section and adapted to be mated with the upper abutment tip region when the upper contacting arm is downwardly depressed by the CPU.
