Solar Coach Light With Removable Shade And Hanging Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improved exterior light fixtures that do not require connection to the electric grid, offering more flexibility and durability in outdoor installations.
Innovation Solution
A solar coach light design featuring a bracket-mounted light fixture with a solar panel, battery cell, and removable shade assembly, which includes a frame with specific peripheries and cap configurations to protect the light bulb and electronic components from the environment, and a hanging assembly for adjustable orientation, allowing for self-adjustment and self-stabilization to maximize sunlight capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the light fixture is designed with a removable shade assembly and frame structure, then ease of maintenance and component access are improved, but device complexity increases
Solution Approach 1:
The light fixture is divided into separable components including a removable shade assembly, frame, cap, and internal components (battery cell, solar panel, socket). This segmentation allows individual parts to be accessed, removed, or replaced independently, significantly improving ease of maintenance while the modular design actually reduces overall complexity by making the system more manageable.
Solution Approach 2:
The shade assembly is designed to be completely removable from the frame, allowing access to internal components without disassembling the entire fixture. The battery cell and socket can be extracted independently, enabling easy replacement of worn components while maintaining the integrity of the remaining structure.
2Use of energy by moving object
If the solar panel is mounted on a sloped front face with greater area, then energy capture is improved, but manufacturing precision requirements increase
Solution Approach 1:
The front face of the light fixture enclosure is designed with a specific slope angle and enlarged area specifically at the location where the solar panel is mounted. This local modification optimizes solar energy capture without requiring the entire fixture to be manufactured with high precision, as only the front face geometry needs to accommodate the sloped solar panel mounting.
3Object-affected harmful factors
If the frame has narrowed distal periphery segments, then protection from environment is improved, but ease of manufacture decreases
Solution Approach 1:
The frame's distal periphery features asymmetric narrowing where the second segments are specifically made narrower than the first segments. This asymmetric design provides enhanced protection at critical exposure points (likely the distal end more exposed to environmental elements) while maintaining simpler, wider sections elsewhere that are easier to manufacture. The asymmetric geometry allows targeted environmental protection without requiring complex manufacturing throughout the entire frame.
