Mobile cabin with ventilation system and a method for ventilation thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soundproof cabins lack mobility and stability during use, often requiring dismantling for relocation, and existing mobile cabins are not soundproof or have inadequate ventilation systems, leading to increased noise levels and instability.
Innovation Solution
A monolithic cabin design with adjustable support legs and 360° rotating wheels for easy relocation, combined with a ventilation system featuring a straight one-channel air inlet and outlet with sound-absorbing devices to maintain air circulation and sound absorption, allowing for interconnection and detachment of modules without dismantling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cabin is designed to be mobile with wheels for easy relocation, then ease of operation is improved, but stability during use deteriorates because the cabin only rests on wheels
Solution Approach 1:
The support system transitions from a static wheel-only design to a dynamic system where wheels serve during relocation and adjustable support legs provide stability during use. The support legs can be extended to contact the ground, creating a stable tripod or quadripod configuration when the cabin is in use, while retracting to allow mobile operation.
Solution Approach 2:
The support system serves multiple functions: wheels enable mobile relocation, while adjustable support legs provide both additional support during relocation and stable grounding during use. This multi-functional design allows the same structure to fulfill both mobility and stability requirements without requiring separate systems.
2Quantity of substance
If a two-channel air duct is used to direct air around the horizontal partition wall, then air circulation is achieved, but ventilation power and speed are reduced
Solution Approach 1:
The ventilation system is segmented into separate functional channels: a vertical channel for high-speed air intake through the ceiling with sound absorption, and a horizontal channel for air distribution. This segmentation allows each channel to be optimized independently - the vertical channel maximizes air intake speed while the horizontal channel distributes air effectively, avoiding the power losses of a two-channel recirculation design.
Solution Approach 2:
Instead of directing air horizontally around partition walls as in conventional designs, the invention inverts the approach by introducing air vertically through the ceiling directly into the workspace. This vertical introduction method eliminates the need for air to travel around obstacles, maintaining high ventilation speed and power while achieving effective air circulation.
3Productivity
If ventilators operate at higher speed to increase air circulation, then ventilation effectiveness is improved, but noise level entering the cabin increases
Solution Approach 1:
The noise-generating elements (ventilators) are extracted from the cabin interior and positioned in the external part of the ceiling. The air intake passage is also separated from the workspace, with sound-absorbing devices installed in the passage itself. This extraction and separation allow high-speed ventilation operation outside the cabin without transmitting noise into the interior space.
Solution Approach 2:
Sound-absorbing devices are introduced as intermediary elements in the air intake passage. These devices act as mediators that allow air to flow through the passage at high speed while absorbing the noise generated by the ventilators and external environment, preventing noise transmission into the cabin interior.
4Ease of operation
If air outlets are positioned in the side wall to enable air flow, then ventilation function is achieved, but the cabin cannot be positioned next to other cabins or walls
Solution Approach 1:
The air outlet position is moved from the horizontal side wall to the vertical ceiling plane, utilizing the vertical dimension for air discharge. This dimensional change allows air outlets to be positioned on the ceiling away from side walls, enabling the cabin to be placed adjacent to other cabins or walls while maintaining effective air circulation and avoiding blocked air flows.
