Sliding Lampshade Light Fixture for Adjustable Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems for office or factory spaces require replacement of the entire light fixture or lampshade to adjust light intensity, which is costly and involves downtime.
Innovation Solution
A light fixture with a sliding lampshade and snap-fit mechanism, allowing the lampshade to be positioned in different retaining-locking recesses to change the light beam from focused to diffused, without replacing the lampshade or entire fixture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the entire light fixture or lampshade is replaced to change light intensity, then the lighting requirements are met, but the cost and downtime increase
Solution Approach 1:
The lampshade is divided into multiple modular segments that can be independently removed and replaced. Each segment corresponds to a specific recess position, allowing users to swap only the necessary portion rather than replacing the entire lampshade or fixture, thereby reducing downtime and cost while achieving desired light intensity levels.
Solution Approach 2:
The lampshade is designed with dynamic adjustability through multiple recess positions (first, second, third recesses) that allow changing the light beam characteristics from focused to diffused. This dynamic configuration enables light intensity adjustment without replacement, resolving the contradiction between meeting illumination requirements and minimizing downtime.
2Illumination intensity
If the entire light fixture or lampshade is replaced to change light intensity, then the lighting requirements are met, but the cost increases
Solution Approach 1:
The lampshade is divided into multiple modular segments that can be independently removed and replaced. Each segment corresponds to a specific recess position, allowing users to swap only the necessary portion rather than replacing the entire lampshade or fixture, thereby reducing downtime and cost while achieving desired light intensity levels.
Solution Approach 2:
The modular lampshade segments can be removed, replaced, and reused in different configurations. Instead of discarding entire fixtures or lampshades, users can recover and reuse the same components in different recess positions to achieve varying light intensities, reducing material cost and waste.
3Adaptability or versatility
If the lampshade is fixed in position, then the structure is simple, but the adaptability to different lighting needs is reduced
Solution Approach 1:
The lampshade is divided into multiple modular segments that can be independently removed and replaced. Each segment corresponds to a specific recess position, allowing users to swap only the necessary portion rather than replacing the entire lampshade or fixture, thereby reducing downtime and cost while achieving desired light intensity levels.
Solution Approach 2:
The light fixture body incorporates multiple recesses that can accommodate the same or different lampshade segments, enabling a single fixture to perform multiple lighting functions (focused, partially diffused, diffused). This universal design increases adaptability without proportionally increasing overall structural complexity.
