Insulative Boot for Power Distribution Splice Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power distribution systems face challenges in effectively insulating splices within tight confines, particularly during the assembly of shipping splits, which can lead to electrical issues and safety concerns.
Innovation Solution
The use of an insulative boot with a movable design that fits around the splice, featuring openings matching the conductor shapes and extensions to secure the splice, providing a closed state for insulation and easy access when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional rigid insulating covers are used to cover splices, then electrical insulation is provided, but the covers cannot be easily installed or removed in tight spaces
Solution Approach 1:
The insulating cover is designed with a flexible bias that allows it to transition between collapsed and expanded states. The cover naturally wants to collapse to a reduced volume but can be forced into an expanded state for installation, then returns to collapsed state for removal. This dynamic behavior resolves the contradiction between providing rigid insulation and enabling easy operation in tight spaces.
Solution Approach 2:
The insulating cover collapses to a compact nested state that fits within tight spaces and can be easily stored or removed. When installed, it expands to envelop the conductor and splice. The nested collapsed state allows the cover to be installed over existing conductors without requiring large clearance spaces.
2Ease of operation
If the insulating cover is designed to be flexible and collapsible, then ease of installation is improved, but the structural strength for maintaining insulation may be reduced
Solution Approach 1:
The cover transitions from a flexible collapsed state during installation to a rigid expanded state during operation. The bias toward collapse provides flexibility for installation, while the expanded configuration provides the structural strength needed for insulation. This dynamic transformation resolves the contradiction between flexibility and strength.
Solution Approach 2:
The insulating cover combines multiple functions: structural insulation support, mechanical protection, and ease of installation/removal. By integrating these functions into a single component that can change state, the design achieves both flexibility for installation and strength for insulation without requiring separate components.
3Reliability
If the insulating cover remains in a fixed expanded state, then insulation coverage is maintained, but access to the splice for maintenance becomes difficult
Solution Approach 1:
The insulating cover is designed to dynamically transition between expanded and collapsed states. It remains expanded to maintain insulation coverage during normal operation but can be collapsed to allow access to the splice for maintenance. This dynamic behavior resolves the contradiction between maintaining coverage and enabling repair access.
Solution Approach 2:
The cover has a built-in bias toward collapse that automatically returns it to the collapsed state when the expansion force is removed. This self-service characteristic allows the cover to be easily collapsed for maintenance access without requiring additional mechanisms or tools, then automatically returns to the insulated state when reinstalled.

AI summary
A power distribution assembly includes a first conductor having a first conductor end and a first shape in cross-section and a second conductor having a second conductor end and a second shape in cross-section. A splice couples the first conductor end to the second conductor end. An insulative boot has a first opening of the first shape, wherein the insulative boot encompasses the first conductor end. The insulative boot also has a second opening having the second shape, wherein the second opening encompasses the second conductor end. The insulative boot has a cavity between the first end and the second end, wherein the cavity is configured to encompass the splice.
