Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Weld cable terminals are prone to damage during transport and storage, affecting power transmission due to exposure to external forces and environments, leading to potential disruptions in welding operations.
Innovation Solution
A weld cable connector system with a terminal protection system that includes a cap, base, and tether, featuring a twist-lock mechanism and insulating materials to securely cover and protect the terminals from external damage, ensuring reliable power transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If weld cable terminals are left exposed during transport and storage, then ease of operation is improved (terminals remain accessible), but reliability deteriorates (terminals are damaged by external forces and environment)
Solution Approach 1:
The protection system is divided into separate components: a cap that covers the terminal, a base that attaches to the cable, and a tether that connects the cap to the base. This segmentation allows each component to perform its specific function while keeping the overall system relatively simple and easy to manufacture.
Solution Approach 2:
The cap acts as an intermediary element between the terminal and the external environment. It provides a protective barrier that prevents direct contact between harmful external factors (dust, moisture, physical damage) and the terminal, while still allowing the terminal to be accessed when needed by simply removing the cap.
2Reliability
If a protection system is added to cover terminals, then reliability is improved (terminals are protected from damage), but device complexity increases (additional components required)
Solution Approach 1:
The protection system is designed to be dynamic rather than fixed. The cap can be easily attached and detached from the terminal, allowing the system to transition between protected and accessible states. This dynamic design ensures that terminals remain accessible when needed while being protected during transport and storage.
Solution Approach 2:
The tether automatically retains the cap near the cable end, providing self-service functionality. When the cap is removed from the terminal, the tether prevents it from being lost and makes it easy to reattach, reducing the operational effort required to protect and access the terminal.
3Reliability
If a twist-lock mechanism is used to secure the cap, then reliability is improved (cap remains firmly attached), but device complexity increases (locking mechanism required)
Solution Approach 1:
The twist-lock mechanism replaces more complex mechanical fastening systems (such as screws, clips, or adhesives) with a simpler rotational locking action. The cap features a locking portion that engages with a corresponding feature on the terminal through a twisting motion, providing secure attachment with minimal manufacturing complexity.
