Desk with Integrated Adjustable Lamp Arm for Space-Saving Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional desks with external lamps are cumbersome and obstructive, limiting space and flexibility in positioning, and the integrated lamp solutions, like rotatable arms, do not provide optimal adjustable lighting.
Innovation Solution
A desk with an integrated light source featuring adjustable arms that pivot from a lowered to a raised position, allowing for multiple directional adjustments of the light beam to ensure optimal illumination without encroaching on the work surface, using LED light sources that can be powered by batteries or the electrical network, and can be manually or motor-driven for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a self-standing lamp is used to illuminate the work surface, then the lighting function is achieved, but the lamp reduces the available space and obstructs the user
Solution Approach 1:
The lamp is integrated into the desk structure itself, merging the lighting function with the furniture. The arm is pivoted on the desk edge and the lamp head is positioned to illuminate the work surface from within the desk's footprint, eliminating the need for separate space-occupying lamp stands.
Solution Approach 2:
The lamp arm utilizes the vertical dimension by pivoting from a horizontal resting position to an elevated operative position. This allows the light source to be positioned above the work surface without occupying horizontal desk space, effectively moving the lighting function to a different spatial dimension.
2Area of stationary object
If a rotatable arm with lamp is integrated into the desk, then the lamp is no longer self-standing and space is saved, but the arm can only be brought into two positions limiting lighting adjustment
Solution Approach 1:
The arm is divided into multiple segments that can rotate relative to each other at different joints. This segmentation allows independent adjustment of each segment, enabling the lamp head to reach multiple positions and angles for optimized lighting coverage across the work surface.
Solution Approach 2:
The arm transitions from a static two-position mechanism to a dynamic multi-position system with multiple rotation joints. Each joint can be independently adjusted to different angles, providing continuous adaptability in light beam direction rather than being constrained to fixed positions.
3Illumination intensity
If the lamp is positioned to illuminate the work surface, then visibility is improved, but electrical connecting wires create obstacles and limit positioning flexibility
Solution Approach 1:
The electrical connecting wires are extracted from the visible workspace and routed through channels within the desk structure. This removes the wires from the user's interaction space, eliminating obstacles while maintaining power supply to the integrated lamp.
Solution Approach 2:
The electrical wiring system is nested within the desk's internal structure, with conduits and channels integrated into the furniture design. This allows the wires to be concealed within the desk body, keeping the workspace clean and unobstructed while maintaining electrical connectivity.
