Insulated Battery Clamp Assembly for Interference-Free Cable Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current battery clamps used in jump starting cables or battery jump starters often cause mechanical interference with users' fingers or tools when connecting or disconnecting battery cables, leading to inefficiencies and safety concerns.
Innovation Solution
A battery clamp device comprising an outer insulating battery clamp connected to an inner conductive battery clamp via a snap fit or mechanical connection, featuring a cylindrical-shaped metal plate battery cable connector that secures and anchors the cable end within a receiver, preventing mechanical interference by positioning the connector at the handle end and using a split or continuous design to crimp closed for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery clamp uses a traditional single-piece metal design, then it provides good electrical conductivity and structural strength, but it causes mechanical interference with user's fingers or tools when connecting or disconnecting battery cables
Solution Approach 1:
The battery clamp is divided into two distinct components: an inner metal clamp member and an outer insulating clamp member. The inner member provides conductivity and clamping force, while the outer member provides insulation and prevents mechanical interference. This segmentation allows each component to fulfill its specific function without causing the harmful effects of the other.
Solution Approach 2:
The outer insulating clamp member acts as an intermediary between the user's fingers/tools and the inner metal clamp member. This intermediate layer prevents direct mechanical contact and interference while still allowing the clamping function to be performed effectively.
2Reliability
If the battery clamp uses an outer insulating clamp and inner metal clamp nested design, then it prevents mechanical interference and improves safety, but it increases device complexity
Solution Approach 1:
The inner metal clamp member is nested within the outer insulating clamp member, with both members sharing similar structural features such as handle portions and clamp portions. This nested arrangement allows the components to be integrated compactly while maintaining their individual functions, reducing the overall space required and simplifying the assembly process.
Solution Approach 2:
The patent combines two previously separate components (metal clamp and insulating cover) into a more integrated nested structure. The connection mechanisms (such as tabs and slots, or interference fits) merge the two components into a unified assembly that functions as a single operational unit, reducing complexity despite the added safety features.
3Reliability
If the battery clamp uses a nested two-component design with connection mechanisms, then it prevents mechanical interference and improves safety, but it increases manufacturing complexity
Solution Approach 1:
The connection mechanisms between the inner and outer clamp members are designed to be pre-formed during the manufacturing process. For example, tabs and slots are molded into the components during injection molding, and interference fit features are created during metal forming. This preliminary action eliminates the need for additional assembly steps, reducing manufacturing complexity despite the two-component design.
Solution Approach 2:
The connection mechanisms are designed to self-align and self-secure during assembly. The tabs automatically engage with the slots, or the interference fit components self-lock into place without requiring additional fasteners or complex assembly procedures. This self-service approach simplifies the manufacturing process while maintaining the safety benefits of the nested design.
