Solar Connector Assembly Tool for Tactile Torque Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Installers often overtighten and damage electrical connector end caps or main bodies during installation due to insufficient tactile feedback from conventional tools, and these tools can be awkward to use, especially in tight spaces like between solar panels and roofs.
Innovation Solution
The development of an electrical connector installation tool comprising an end cap tool and a main body tool, designed to provide greater tactile feedback and prevent overtightening. The tools are structured for hand gripping and can be used coaxially with the electrical connector, allowing for easier assembly in tight spaces. Additionally, the tools are magnetically connected to reduce the risk of misplacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If conventional spanner wrenches with long handles are used to tighten end caps, then torque application is improved, but tactile feedback is insufficient leading to overtightening
Solution Approach 1:
Instead of using a long-handle wrench that provides mechanical advantage but poor feedback, the patent inverts the approach by using a short-handled tool where the operator directly grips and rotates the tool body itself. This direct grip provides immediate tactile feedback while the magnetic coupling between tools provides sufficient holding force without requiring long leverage arms.
2Ease of operation
If two separate spanner wrenches are used to hold the end cap and main body, then gripping capability is improved, but tool complexity and risk of misplacement increase
Solution Approach 1:
The patent merges two separate spanner wrenches into a single integrated tool assembly. The first tool engages the end cap while the second tool engages the main body, and both tools magnetically couple together to form one unified device. This eliminates the need to manage two separate tools while maintaining the capability to grip both components simultaneously.
Solution Approach 2:
The magnetic coupling between the two tool components acts as an intermediary mechanism that automatically keeps the tools connected during operation. The magnetic field serves as the mediator that holds the tools together without requiring mechanical fasteners or manual coordination, reducing complexity while maintaining gripping capability.
3Force
If conventional tools with long handles are used, then leverage is improved, but maneuverability in tight spaces deteriorates
Solution Approach 1:
The patent inverts the traditional wrench design by eliminating long handles and using short, compact tool bodies that are directly gripped by hand. This provides sufficient leverage through direct hand torque application while enabling easy maneuverability in confined spaces between solar panels and roofs.
4Productivity
If power tools such as impact hammers with sockets are used, then installation speed is improved, but risk of overtightening and damage increases
Solution Approach 1:
The patent incorporates tactile feedback through direct hand gripping of the tool body, allowing the operator to sense when the end cap is properly tightened. This human sensory feedback prevents overtightening and damage while maintaining reasonable installation speed through the ergonomic, easy-to-operate design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tool effectively prevents overtightening, making the installation process safer and reducing damage to components. It allows for easier assembly in confined spaces and reduces the risk of tool misplacement, enhancing overall installation efficiency.
Implementation Method 1
The end cap tool and the main body tool may be structured to magnetically connect. This reduces the risk of misplacing the tools.

AI summary
An electrical connector installation tool for electrical connectors that include a main body and a screw-on end cap. The electrical connector installation tool includes a separate end cap tool and main body tool. The end cap tool and the main body tool may be structured to be hand gripped and hand turned around the tool body. To accommodate different electrical connectors of different sizes or different types, the end cap tool may include a pair of end cap sockets positioned on opposite ends of a hollow interior within the end cap tool. The end cap sockets may be sized and shaped to receive and turn screw-on end caps of different sizes. For example, one end cap socket could be sized and shaped to accommodate MC4 electrical connectors while the other end cap socket could accommodate H4 electrical connectors with larger screw-on end caps.
