Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transformer housings for outdoor lighting lack adequate illumination at the terminal block, making it difficult to connect or remove wires due to insufficient lighting within the housing.
Innovation Solution
A power transformer assembly with a terminal block made of transparent or translucent materials, featuring a light source positioned underneath to illuminate the connections, and a switch that activates the light when the housing is opened, ensuring better visibility for wire connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the transformer housing uses a traditional opaque terminal block, then the housing structure is simple and cost-effective, but the interior illumination is insufficient making wire connections difficult
Solution Approach 1:
The terminal block is made from translucent material that changes its optical properties to allow light transmission. This enables the terminal block to transmit illumination from the housing interior to the exterior, solving the illumination problem while maintaining a simple single-piece structure without additional lighting components
Solution Approach 2:
The translucent terminal block acts as an intermediary element between the housing interior lighting and the external environment. It mediates the transmission of light while maintaining structural integrity and electrical insulation, allowing illumination without requiring direct modification of the housing structure
2Illumination intensity
If the terminal block is made of transparent or translucent material, then illumination is improved for wire connections, but the material selection becomes more limited
Solution Approach 1:
The terminal block utilizes translucent materials with varying degrees of light transmission properties. Different translucent materials can be selected based on specific application requirements for light transmission, electrical insulation, and mechanical properties, providing material versatility while maintaining the illumination function
Solution Approach 2:
The invention employs composite material construction where translucent material is combined with conductive elements (such as metal lugs or contacts) to create a multi-functional terminal block. This composite approach allows the single piece to provide both optical transmission for illumination and electrical connection functionality
3Illumination intensity
If the terminal block is illuminated from underneath, then wire connection visibility is improved, but the light may not reach adjacent labels effectively
Solution Approach 1:
The translucent terminal block is designed with optical properties that facilitate light diffusion and redirection. The material composition and geometric design enable light to scatter and reach adjacent areas including labels, ensuring comprehensive illumination of both connection points and identification markers
Solution Approach 2:
The illumination approach extends from a single-point source to multi-dimensional light distribution. The translucent material and housing design work together to distribute light in multiple directions, ensuring that both the wire connection areas and adjacent labels receive adequate illumination from the bottom-mounted light source
