Restricting Pole With Retention Groove For Torsioned Wire
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bolster structures for electronic packages, particularly those using torsion spring wires, fail to efficiently retain the wire in position due to the instability of fastening shims, which complicates automation in assembly processes.
Innovation Solution
A retention groove is formed around the top portion of the restricting pole to securely hold a press ring, which snaps down to restrain the torsioned wire, preventing improper movement and enhancing stability during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fastening shim is used to retain the torsioned wire, then the wire can be held in position, but the shim easily rotates and fails to efficiently hold the wire
Solution Approach 1:
A restricting pole is introduced as an intermediary component between the fastening shim and the torsioned wire. The pole receives the shim at its top and extends downward to directly restrict the wire, providing stable positional retention while allowing the shim to be easily installed and removed from the pole's top surface.
2Reliability
If a fastening shim is screwed upon the restricting pole beside the side wall, then the wire may be held, but the process is not fit for automation assembling
Solution Approach 1:
The restricting pole is designed with a top surface that directly receives and holds the fastening shim, eliminating the need for screwing operations. The shim can be simply placed onto the pole's top and then pushed down to engage the wire, creating a self-contained retention mechanism that is easily automatable without complex fastening tools or procedures.
3Reliability
If the fastening shim is used to retain the torsioned wire, then the wire can be held, but the shim requires complex screwing operations that complicate assembly
Solution Approach 1:
The screwing operation is extracted and removed from the assembly process. The restricting pole is designed so that the fastening shim is simply received at the pole's top surface and can be directly pushed down to engage the wire, eliminating the need for screws, nuts, or any threaded fastening mechanisms and significantly simplifying the overall assembly process.
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 solution effectively maintains the torsioned wire in position, enhancing the normal forces between the heat sink, CPU, and electrical connector contacts, while simplifying the assembly process through secure retention and reduced risk of torsion-induced movement.
Implementation Method 1
a press ring is downwardly snapped into the retention groove so as to restrain the torsioned wire
Implementation Method 2
a torsioned wire of the bolster assembly provides a downward force upon an up-and-down movable stud

AI summary
The load force bolster assembly includes a metallic stiffener. A carrier associated with a CPU (Central Processing Unit) is located upon the load force bolster assembly and positioned upon the electrical connector. A heat sink is located upon both the carrier and the load force bolster assembly wherein a torsioned wire of the bolster assembly provides a downward force upon an up-and-down movable stud which is secured to a screw of the heat sink so as to downwardly push the heat sink, thus enhancing the normal forces among the heat sink, the CPU and the contacts of the electrical connector. To efficiently hold the torsioned wire in position around a bottom corner of the stiffener, a retention groove is formed around the top portion of the restricting pole, and a pressing ring is downwardly snapped into the retention groove so as to restrain the torsioned wire in position.
