Automatic Cable Splice with Transparent Casing for Visual Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Utility linemen face difficulties in ensuring proper insertion of cables into automatic splices due to non-transparent casings, leading to potential failure of spliced connections and safety risks, especially in harsh environmental conditions.
Innovation Solution
The design includes a casing with a jaw assembly, biasing member, guide, and bullet cup, where the guide helps in cable alignment, and the bullet cup secures the jaw assembly open for easy cable insertion, with a biasing member ensuring secure clamping once the cable is fully inserted, enhancing visibility and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the casing is made non-transparent for protection and durability, then the structural strength and reliability are improved, but the ability to visually inspect cable positioning is lost
Solution Approach 1:
The patent applies transparency changes rather than color changes. The casing transitions from opaque to transparent to allow visual inspection while maintaining protection. This resolves the contradiction by making the casing transparent when inspection is needed while retaining its protective function.
Solution Approach 2:
The casing's transparency is made dynamic rather than static. It can switch between transparent and opaque states, allowing the system to adapt to different operational phases: transparent during cable insertion for visual confirmation, and opaque during normal operation for protection and durability.
2Ease of operation
If significant force is applied to insert cables into the splice, then the cable insertion is achieved, but the difficulty of knowing proper insertion depth increases
Solution Approach 1:
The transparent casing provides visual feedback to the operator during cable insertion. The lineman can directly observe the cable's position and insertion depth through the transparent casing, eliminating the need to apply excessive force or guess the insertion depth. This visual feedback mechanism resolves the contradiction between ease of operation and measurement precision.
3Ease of operation
If the jaw assembly is held open for easy cable loading, then the ease of operation is improved, but the risk of accidental closure and cable release increases
Solution Approach 1:
The bullet cup is pre-positioned to hold the jaw assembly in an open state before cable insertion. This preliminary action allows easy cable loading without requiring the lineman to constantly hold the jaws open. Once the cable is inserted, the jaw assembly can be securely closed, eliminating the risk of accidental closure during the loading phase while maintaining connection security afterward.

AI summary
A cable splice includes a casing, a jaw assembly, a biasing member, a guide, and a bullet cup. The casing has an opening and an interior cavity. The jaw assembly is positioned in the interior cavity and moveable between a loading position and a terminated position. The biasing member biases the jaw assembly towards the terminated position. The guide includes a receiving end and a shaft extending at least partially into the interior cavity.
