A workspace wall system designed for placement on a desk, featuring a main wall element, wing panels, sound detection elements, and sound generating devices for active noise reduction, along with an air purifying device to improve air quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a workspace wall with active noise reduction is placed on a desk, then noise levels within the noise reduction area are reduced, but the device complexity increases
Solution Approach 1:
The workspace wall combines multiple noise reduction mechanisms (active noise reduction speakers, passive noise reduction layers, and wing panels) into a single integrated device that can be placed on a desk, thereby reducing noise levels while managing the complexity through unified design
Solution Approach 2:
The workspace wall is divided into functional segments including the main wall element, wing panels, sound detection elements, and sound generating devices, allowing each component to be optimized independently while working together as a cohesive system
2Object-affected harmful factors
If an air purifying device is added to the workspace wall, then air quality is improved, but the device complexity increases
Solution Approach 1:
The air purifying device is integrated with the workspace wall by combining air inlet, air outlet, and purifying units with the existing noise reduction structure, allowing dual functionality (noise reduction and air purification) in a single device without proportionally increasing complexity
3Ease of operation
If the workspace wall is designed to be portable and manually portable by a single person, then ease of operation is improved, but the strength and stability may be compromised
Solution Approach 1:
The workspace wall incorporates foldable wing panels and reversible convertibility between stowage and operating orientations, allowing the structure to be easily assembled, disassembled, and transported by a single person while maintaining structural integrity during use through proper engineering of the folding mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The workspace wall effectively reduces noise levels within a designated area by up to 10 dB at specific frequencies, while the air purifying device improves indoor air quality, enhancing concentration and productivity.
Implementation Method 1
a system and method for quieting unwanted sound by generating a 'cancellation signal' which destructively interferes with an unwanted sound source at the user's ear
Implementation Method 2
at least one sound generating device, preferably for active noise reduction, and/or a passive noise reduction element
