Tunable Cast Grounding Block for Vehicle Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grounding block assemblies for vehicles lack efficient and integrated solutions for routing electrical grounding wires/straps without requiring additional components, particularly in dry sections where no holes are available in the casting base plane, leading to potential misalignment and instability.
Innovation Solution
A casting with a raised integrated grounding block featuring tunable surfaces and an anti-rotational tab attachment via an eyelet, allowing for secure routing of electrical grounding wires/straps without additional attachments, ensuring stability and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a traditional grounding block assembly is used without integrated routing features, then the grounding function is provided, but additional separate components are required for routing and securing the grounding wire/strap
Solution Approach 1:
The patent integrates the grounding block, routing surfaces, eyelet, and anti-rotational tab into a single cast component. This merging of previously separate elements (grounding block, wire routing features, and anti-rotational mechanisms) eliminates the need for multiple separate components while maintaining all necessary functions for grounding wire installation and securing.
Solution Approach 2:
The integrated casting serves multiple functions simultaneously: it provides the grounding electrical connection, offers tunable surfaces for wire routing in various directions, includes an eyelet for wire attachment, and incorporates an anti-rotational tab for preventing rotation. This multi-functionality in a single component addresses the need for routing efficiency without increasing device complexity.
2Stability of the object's composition
If grounding blocks are used in dry sections without holes in the casting base plane, then integration is maintained, but routing options for grounding wires are limited and may cause misalignment
Solution Approach 1:
Instead of providing routing holes in the base plane (two-dimensional solution), the patent creates three-dimensional tunable surfaces that extend upward from the casting. These surfaces provide multiple routing paths in various directions (horizontal, vertical, angled) without compromising the integrated composition or requiring base plane holes.
Solution Approach 2:
The tunable surfaces can be configured in different orientations (horizontal, vertical, angled) to adapt to various wire routing needs. This dynamic adaptability allows the integrated grounding block to accommodate different installation scenarios while maintaining structural integrity and avoiding misalignment issues.
3Reliability
If separate anti-rotational components are used with grounding blocks, then rotation prevention is achieved, but the assembly requires additional attachments and components
Solution Approach 1:
The anti-rotational tab is integrated directly into the casting as part of the grounding block assembly, eliminating the need for separate anti-rotational components. This tab extends from the casting and works in conjunction with the grounding block to prevent rotation, maintaining reliability while reducing the number of required attachments.
