Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telecommunications systems face inefficiencies in circuit protection due to the space requirements of traditional 5-pin protection blocks, which are not adequately compact for high-density signal arrays, leading to suboptimal use of space and increased equipment needs.
Innovation Solution
A compact protection block with a two-dimensional array of sockets and grounding bars, designed to accommodate small form-factor overvoltage protection plugs, allowing for increased connection density within the same footprint as traditional blocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional 5-pin protection blocks are used, then reliable overvoltage protection is provided, but the space utilization is inefficient and connection density is low
Solution Approach 1:
The patent transitions from a linear one-dimensional array of protection locations to a two-dimensional array arrangement. This dimensional change allows significantly more protection sockets to be packed into the same physical footprint, effectively doubling the connection density while maintaining the same block dimensions (approximately 7.9 inches by 5.8 inches).
Solution Approach 2:
The patent combines multiple protection circuits into a single integrated protection block housing. By merging numerous individual protection locations into one unified structure with a two-dimensional socket array, the system achieves higher density without requiring multiple separate blocks, thereby optimizing space utilization in telecommunications cabinets.
2Ease of operation
If Krone-style connector blocks with circuit protection locations are used, then connection functionality is provided, but space efficiency is reduced due to linear array arrangement
Solution Approach 1:
The invention reconfigures the protection locations from a linear one-dimensional array (as in Krone-style blocks) to a two-dimensional array. This allows the same number of connection locations to occupy less physical space, or alternatively, doubles the capacity within the same footprint, thereby improving space efficiency while maintaining full connection functionality.
3Quantity of substance
If protection block capacity is increased to protect more signal lines, then coverage is improved, but the block size and complexity increase
Solution Approach 1:
By arranging protection sockets in a two-dimensional grid pattern rather than a linear sequence, the patent increases the number of protected circuits within the same housing dimensions. This geometric optimization allows capacity doubling without proportionally increasing structural complexity, as the fundamental housing and mounting structure remain similar to traditional blocks.
Solution Approach 2:
The protection block employs standardized socket and plug designs that can accommodate various overvoltage protection elements (gas tubes, solid state devices). This universal interface allows the same block structure to support different protection technologies and configurations, increasing functional capacity without requiring complex specialized structures for each variant.

AI summary
A protection block and method of use are disclosed. The protection block includes a rectangular housing having a front, a rear, and top, bottom, left, and right sides. The protection block also includes a plurality of sockets arranged in a two-dimensional array in the front of the housing, each of the plurality of sockets associated with two pairs of opposed, normally open contacts. Each of the plurality of sockets is arranged to receive an overvoltage protection plug that separately connects each of the two pairs of contacts. The protection block also includes a plurality of electrical connections in a second discrete region of the block separate from the first discrete region, the plurality of electrical connections electrically connected to the contacts. The protection block also includes a grounding bar associated with one or more of the sockets and positioned for electrical connection to a ground connection of an overvoltage protection plug when inserted into a socket.
