Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If splice kits with large number of sub-components are used to connect cables with large ODs, then the cables can be connected, but the overall complexity of the assembling process increases
Solution Approach 1:
The patent integrates multiple sub-components into a single housing member that includes both first and second engaging portions for accommodating different cable types. The terminal block is integrated within the housing, eliminating the need for separate mounting structures. This merging reduces the number of discrete components while maintaining the ability to connect cables with large outer diameters.
Solution Approach 2:
The housing member is designed with universal functionality to accommodate both optical cables and cables with larger outer diameters through its integrated engaging portions. The single housing structure performs multiple functions: providing structural support, enabling cable engagement, housing the terminal block, and facilitating electrical connection, thereby reducing overall system complexity.
2Adaptability or versatility
If splice kits with large number of sub-components are used, then cables with large ODs can be connected, but the overall manufacturing cost increases substantially
Solution Approach 1:
By combining multiple sub-components into an integrated housing member with built-in engaging portions and terminal block accommodation, the patent reduces the total number of parts that need to be manufactured, stored, and assembled. This integration simplifies the manufacturing process and reduces overall production costs while maintaining adaptability to connect various cable types including those with large outer diameters.
3Adaptability or versatility
If splice kits with large number of sub-components are used, then cables can be connected, but the overall length of the splice kit increases substantially
Solution Approach 1:
The integration of the terminal block within the housing member and the consolidation of engaging portions into the housing structure eliminates the need for separate mounting brackets and extended component arrangements. This merging reduces the overall length of the splice kit while maintaining the capability to connect various cable types.
4Adaptability or versatility
If current splice kits are used, then cables can be connected, but reliable electrical connections are not provided and durability is low
Solution Approach 1:
The housing member is pre-configured with integrated engaging portions and internal structures that guide cables into proper positions before connection. The terminal block is pre-positioned within the housing with alignment features that ensure correct cable placement and secure electrical contact, thereby improving connection reliability and durability from the outset.
5Adaptability or versatility
If current splice kits are used, then cables can be connected, but sufficient water-tight provisions are not provided, making electrical connections prone to moisture ingress
Solution Approach 1:
The integration of all connection components within the sealed housing structure creates a unified protected environment. The housing member encompasses the terminal block and cable engagement areas, providing comprehensive protection against moisture and contaminants that would otherwise expose electrical connections to harmful environmental factors.

AI summary
A cable connector assembly is disclosed. The cable connector assembly includes a housing member having a first end and a second end defining a passage therebetween. The housing member includes a first engaging portion and a second engaging portion coaxially extending from the first end and the second end, respectively. The housing member is adapted to accommodate at least one terminal block to electrically connect a first cable and a second cable. Further, the cable connector assembly includes a first clamping member adapted to be partially inserted in the first engaging portion of the housing member and to coaxially align with the passage to accommodate insertion of the first cable therein. The first clamping member is adapted to elastically deform to clamp the first cable.
