Goggle Strap Socket Relocation for Weight Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric goggles for preventing fogging in cold weather conditions are uncomfortable due to the weight imbalance caused by electrical connections and the inconvenience of handling electric components, which can lead to stress on the components and hinder easy placement on a helmet.
Innovation Solution
The design includes a resilient strap with an electric socket positioned remotely from the frame, allowing electrical wires to run along the strap to connect the conductive lens to the socket, and a strap clip that attaches to the helmet, keeping the socket away from the frame when placing the goggles on the helmet, along with a strain relief clip to manage the power cable, reducing strain and encumbrance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical connections are integrated into the goggle frame, then the conductive lens can be powered, but the weight distribution becomes unbalanced and comfort decreases
Solution Approach 1:
The electrical connection components (socket and wires) are extracted from the goggle frame and relocated to the headband. The socket is mounted on the headband away from the goggle frame, and wires run along the headband to connect to the lens, separating the electrical system from the optical system to restore balanced weight distribution and improve comfort.
2Reliability
If the goggle frame includes electrical components, then the lens can be heated, but the components are in the way when placing and removing goggles
Solution Approach 1:
The electrical components are extracted from the goggle frame structure and positioned on the headband. The socket is mounted remotely on the headband, and wires are routed along the headband rather than through the frame, eliminating interference with the placement and removal operations.
3Reliability
If the power cable is connected during goggle removal, then continuous power is maintained, but stress is placed on the cable and components
Solution Approach 1:
The headband serves as an intermediary structure that absorbs and distributes mechanical stress during goggle manipulation. The socket is mounted on the headband with sufficient spacing from the frame, creating a buffer zone that protects the electrical connection from stress during placement and removal operations.
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
This configuration enhances user comfort by balancing the weight, reducing stress on components, and allowing easy placement and removal of the goggles without disconnecting the power source, while maintaining effective fog prevention through heated lenses.
Implementation Method 1
Electric goggles typically include conductive strips and/or a resistive coating. Current is circulated through the coating or strips, which generates heat, effectively eliminating fog or frost accumulation on the lens.
Data Source
AI summary
A pair of electric goggles is disclosed. The goggles include a conductive lens mounted onto a frame adapted to be electrically connected to an electric socket in order to raise the temperature of the lens, when powered. The goggles are provided with a strap for attaching to a helmet, the strap has a strap clip designed to have the electric socket attached thereto. The electric socket is meant to be electrically connected to a power supply via a power cable. With the combination of a strain relief clip located below the electric socket, the power cable can be positioned in a predetermined configuration, which unencumbers the user from the power cable when detaching or removing the goggles.
