Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional hardline splice blocks with fixed ports are used, then the device structure is simple, but the installation versatility is limited to only three fixed orientations
Solution Approach 1:
The patent applies the dynamics principle by making the second portion rotatable relative to the first portion, transforming the fixed port orientation into a dynamic, adjustable configuration. This allows the cable interface ports to be rotated to various angular orientations (0°, 90°, 180°, 270°, and intermediate angles) to accommodate different installation requirements, directly resolving the contradiction between installation versatility and device structure by introducing controlled movement without excessive complexity
Solution Approach 2:
The patent implements universality by designing a rotatable mechanism that enables a single splice block to perform multiple orientation functions. Instead of requiring separate fixed blocks for different orientations, this universal design allows one device to provide all orientation options (thru, 90-degree, 180-degree, and other angles) through rotation, thereby improving installation versatility while maintaining relatively simple device structure
2Adaptability or versatility
If two 90-degree adapters are used to vary cable orientation, then installation flexibility improves, but the installation time increases and additional parts are required
Solution Approach 1:
The patent applies the merging principle by integrating the orientation-adjustment function directly into the splice block body through the rotatable second portion, eliminating the need for separate 90-degree adapters. This consolidation allows installers to achieve any desired cable orientation by simply rotating the integrated mechanism rather than assembling multiple discrete components, thereby improving cable orientation flexibility while reducing installation time and the number of required parts
Solution Approach 2:
The patent extracts the orientation-adjustment function from external adapters and incorporates it directly into the splice block structure. By taking out the need for separate adaptive components and embedding the rotational capability within the main device, the system achieves cable orientation flexibility without the time loss and complexity of assembling multiple parts
3Adaptability or versatility
If two 90-degree adapters are used to create different angle combinations, then orientation options increase, but the splice block size becomes undesirably larger
Solution Approach 1:
The patent uses the dynamics principle to provide multiple angle combination options within a compact form factor. By making the second portion rotatable, a single splice block can dynamically assume various angular configurations (0°, 90°, 180°, 270°, and intermediate angles) rather than requiring multiple fixed blocks of different sizes. This dynamic approach maintains a relatively small splice block volume while delivering comprehensive angle combination options through rotational adjustment
4Reliability
If unused ports are left connected in conventional splice blocks, then the device structure remains simple, but signal quality degrades due to antenna effect
Solution Approach 1:
The patent applies the extraction principle by removing the second connecting portion from the device structure when it is not needed for operation. The rotatable mechanism allows the second portion to be positioned such that it does not interfere with the electrical coupling between the first connecting portion and the cable, effectively extracting the potential source of signal degradation (unused ports acting as antennas) from the system while maintaining simple device structure

AI summary
A cable splicing device may include a first portion having a first connection portion structurally configured to connect to a first communication cable and a second portion having a second connection portion structurally configured to connect to a second communication cable. The second portion may be structurally configured to rotate relative to the first portion to adjust an angular orientation of the second connecting portion relative to the first connecting portion so as to permit adjustment of an angular orientation of the first connecting portion relative to the second connecting portion and improve installation versatility and electrical performance.
