Pivotable Terminal Clamp Puller with Detachable Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for pulling out terminal clamps are expensive, inflexible, and space-consuming due to the need for ultrasonic welding and protruding grip sections, making it difficult to handle and access multiple clamps.
Innovation Solution
A device with a pivotable connection between the fastening and grip sections, allowing for detachable attachment and stowage, featuring a dovetail fastening mechanism and a catch hook for secure engagement, reducing material usage and eliminating the need for welding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ultrasonic welding is used to attach the device to the terminal clamp, then the connection is secure and reliable, but the manufacturing cost increases and the process becomes irreversible
Solution Approach 1:
The device is divided into two separate functional parts: a fastening section that attaches to the terminal clamp and a grip section that provides user grip. This segmentation allows the fastening section to be detachably connected to the terminal clamp via a tongue-and-groove mechanism, eliminating the need for irreversible welding while maintaining secure connection during use.
Solution Approach 2:
The connection between the fastening section and terminal clamp is made dynamic and reversible through the tongue-and-groove mechanism with release elements. This allows the device to be securely attached during operation but easily detached when needed, providing both reliability and manufacturing flexibility without requiring expensive ultrasonic welding.
2Ease of operation
If the grip section protrudes rigidly from the terminal clamp, then the grip is easy to access, but the device size increases significantly and access to neighboring clamps becomes difficult
Solution Approach 1:
The grip section is designed to be movable relative to the fastening section through a pivotable connection. When not in use, the grip section can be folded back against the fastening section, reducing the overall device volume and allowing access to neighboring terminal clamps. When needed, the grip section can be extended outward for easy gripping.
Solution Approach 2:
The grip section can be positioned inside or against the fastening section when not in use, creating a compact configuration. This nesting arrangement reduces the protruding dimensions of the device while maintaining full functionality when the grip section is extended.
3Ease of operation
If the grip section is made long and rigid, then it is easy to grip, but it causes interference with neighboring clamps and is rarely used
Solution Approach 1:
The grip section is designed with pivotable movement capability, allowing it to be positioned at different angles and lengths of protrusion. Users can extend the grip section only when needed for gripping, and fold it back when not in use, eliminating continuous interference with neighboring clamps while maintaining ease of grip when required.
4Strength
If a welded connection is used between the fastening section and terminal clamp, then the connection is strong, but it is expensive and not readily reversible
Solution Approach 1:
The device separates the fastening function from the grip function into distinct sections. The fastening section uses a tongue-and-groove mechanism with release elements that provides strong mechanical connection during use but allows easy detachment, replacing expensive welded connections while maintaining connection strength when needed.
