Articulating Sun Shield Assembly for DJ Display Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions fail to provide a manually articulatable sun shade that effectively blocks sunlight from interfering with DJ equipment displays while maintaining a sleek, modern aesthetic and allowing for quick adjustments to changing light conditions.
Innovation Solution
An articulating sun shield with a thin, non-transmissive shield and a base that can be interchangeably flipped, supported by an articulating arm assembly with hinged arm members and a variable-friction pivot joint, allowing for flexible positioning and compact configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a traditional umbrella is used to provide shade, then the DJ is protected from sunlight, but the aesthetic appearance is compromised and the audience's view is obstructed
Solution Approach 1:
The sun shield employs an articulating arm assembly with multiple movable segments that can dynamically adjust their position and angle. This allows the shield to adapt to changing light conditions while maintaining a sleek, modern appearance that does not obstruct the audience's view of the performer.
Solution Approach 2:
The sun shield is divided into multiple segments including a base, articulating arm assembly with multiple arms, and a shield portion. This segmentation allows each component to be optimized independently - the base remains compact, the arms provide articulation freedom, and the shield portion blocks sunlight effectively without obstructing views.
2Adaptability or versatility
If a fixed sun shield is used, then the structure is simple, but the ability to adjust to changing light conditions is limited
Solution Approach 1:
The articulating arm assembly incorporates multiple joints and pivot points that enable dynamic adjustment of the shield's position. The system can quickly transition between different configurations to adapt to changing light conditions throughout the performance.
Solution Approach 2:
The articulating arm assembly features nested segments that can be collapsed into each other when not in use. This nesting capability reduces the overall footprint and simplifies the structure when the shield is not actively adjusting to light conditions.
3Object-affected harmful factors
If a large shield is used to block sunlight, then the blocking effectiveness is improved, but the obstruction of performer's view and audience's view increases
Solution Approach 1:
The shield portion is strategically positioned and sized to block sunlight only in the specific area of the electronic equipment displays. The articulating arm assembly allows the shield to be precisely positioned to protect only what is necessary while leaving the performer's view and audience's view unobstructed.
4Ease of operation
If a manual articulation system is used, then the automation is reduced, but the ease of quick adjustment is improved
Solution Approach 1:
The articulating arm assembly is designed with manual joints and pivot points that can be quickly adjusted by hand. This manual articulation system allows the DJ or technician to rapidly reposition the shield in response to changing light conditions without requiring complex automated mechanisms.

AI summary
A sun shield includes a base, a shield, an articulating arm assembly including first and second arm members, each of the arm members including proximal and distal end portions, the proximal end portions of each of the arm members being hingedly joined. The base is attached to the distal end portion of the first arm member, and the shield is attached to the distal end portion of the second arm member.
