Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In baseband processing units, the small spacing between optical modules due to the specific board thickness limits the disassembly/assembly operation space, leading to a risk of mutual interference during insertion and extraction.
Innovation Solution
The design includes a circuit board with two optical port cages arranged in a thickness direction, each with multiple pins, and a base plate with crimping holes to increase the spacing between optical modules, allowing for a larger disassembly/assembly operation space by thickening the components and positioning extraction levers on the same side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If optical port cages are crimped on both sides of a circuit board with a specific board thickness, then the baseband processing unit achieves a compact structure, but the spacing between optical modules becomes small, limiting disassembly/assembly operation space
Solution Approach 1:
The patent positions both extraction levers on the same side of the circuit board, utilizing the lateral dimension along the board's surface rather than spacing components only in the thickness direction. This dimensional reconfiguration allows operators to access both extraction levers from one side, significantly improving operation space and ease of disassembly/assembly while maintaining the compact vertical structure.
Solution Approach 2:
The patent employs an asymmetric arrangement where extraction levers are positioned on the same side of the circuit board rather than symmetrically on opposite sides. This asymmetric design creates sufficient operational space on one side for handling both optical modules, resolving the contradiction between compact structure and ease of operation.
2Volume of moving object
If optical port cages are crimped on both sides of a circuit board, then the baseband processing unit achieves a compact structure, but the risk of mutual interference between optical modules during insertion and extraction increases
Solution Approach 1:
By moving both extraction levers to the same side of the circuit board, the patent eliminates the spatial overlap and mutual interference that would occur when modules are accessed from opposite sides. This dimensional change allows independent operation of both extraction levers without risk of collision or interference, thereby improving reliability while maintaining structural compactness.
Solution Approach 2:
The patent extracts the extraction levers from the traditional opposite-side configuration and relocates them to the same side, effectively removing the source of mutual interference. This extraction and repositioning of components eliminates the harmful interaction between optical modules during insertion and extraction operations.
3Volume of moving object
If the circuit board has a specific thickness, then the baseband processing unit achieves a compact design, but additional avoidance locations are required to prevent interference between optical modules
Solution Approach 1:
The patent resolves the need for additional avoidance locations by reconfiguring the extraction lever positions in the lateral dimension along the circuit board. Instead of requiring complex avoidance mechanisms or thicker boards, the solution places both extraction levers on the same side, allowing sufficient operational clearance without adding structural complexity or increasing board thickness.
Solution Approach 2:
The same side of the circuit board serves as a universal access point for both optical module extraction operations. By making this side multi-functional for both extraction levers, the patent eliminates the need for separate avoidance locations or specialized structural features, maintaining compact design while reducing device complexity.

AI summary
This application relates to the field of communications technologies, and discloses a baseband processing unit, including a circuit board, a first optical port cage, a second optical port cage, a first optical module, and a second optical module; where the first optical port cage and the second optical port cage are arranged in a thickness direction of the circuit board, both the first optical port cage and the second optical port cage are provided with multiple pins, the second optical port cage is installed on the circuit board, the first optical module is plug-connected to the first optical port cage, and the second optical module is plug-connected to the second optical port cage. A first base plate is disposed on a side that is of the circuit board and that is away from the second optical port cage, the first base plate is fastened on the circuit board, the first base plate is provided with a crimping hole whose opening is located on a surface of a side that is of the first base plate and that is away from the circuit board, and a pin of the first optical port cage is plug-connected to the crimping hole of the first base plate. When a design manner in which the optical port cages are crimped on both sides of the circuit board is used for the baseband processing unit, disassembly/assembly operation space of the two optical modules is relatively large, so as to help disassembly/assembly of the two optical modules.
