Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for influencing and measuring sensory perception in defined spaces, such as intensive care units, face challenges in isolating specific irritant effects due to exposure to various non-specific stimuli, making it difficult to effectively reduce stress and anxiety in patients.
Innovation Solution
A system combining soundproofing devices and optical display devices to create a controlled environment, where acoustically active medical devices are shielded, and visual stimuli are presented within a specific viewing angle, allowing for targeted measurement and influence of a person's state of mind, incorporating sound-absorbing materials and biodynamic lighting to reduce noise and promote relaxation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If acoustically active medical devices are placed in the room for patient treatment, then medical treatment functionality is provided, but noise exposure increases causing stress and anxiety
Solution Approach 1:
The room is segmented into distinct acoustic zones using soundproofing devices. The patient area is separated from the medical device area, allowing medical equipment to operate independently without transmitting noise to the patient space. This segmentation enables both medical functionality and noise reduction to coexist.
Solution Approach 2:
Soundproofing devices act as intermediary elements between the acoustically active medical devices and the patient. These devices absorb and block sound transmission, serving as a buffer that prevents harmful noise from reaching the patient while allowing the medical devices to continue their therapeutic functions.
2Adaptability or versatility
If multiple stimuli are present in the room environment, then comprehensive sensory influence is achieved, but specific irritant effects become difficult to identify and measure
Solution Approach 1:
The sensory stimulation system is divided into separate, controllable channels for different stimulus types (visual, acoustic, olfactory). Each stimulus type can be independently activated and measured, allowing researchers to identify which specific stimulus is producing which effect, thereby maintaining measurement precision while providing comprehensive sensory influence.
Solution Approach 2:
Different regions of the room are designed with specific sensory characteristics. For example, certain areas may have enhanced visual displays while others focus on acoustic stimulation. This local differentiation allows for precise identification of which stimulus in which location is affecting the patient, while still providing overall comprehensive sensory coverage.
3Productivity
If optical display device extends over large viewing angle to influence senses, then visual stimulation effectiveness increases, but device complexity and spatial requirements increase
Solution Approach 1:
The optical display system utilizes the vertical dimension and curved surfaces to achieve wide viewing angles without requiring an excessively large horizontal footprint. By arranging display elements along curved paths and at different heights, the system provides comprehensive visual coverage while managing spatial requirements and device complexity.
