Solution Overview
Problem
Conventional beds with pneumatic features face challenges due to noise and vibrations generated by air pumps, which disrupt sleep quality, and the pumps' shorter lifespan compared to the bed, leading to reduced utility.
Innovation Solution
A bed with an array of independently operable pumps and a controller that selectively couples their outputs to pneumatic chambers, allowing for dynamic adjustment of sleep surface firmness, minimizing pump usage based on wear and sleep stage, and optimizing noise reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single air pump is used to provide pneumatic adjustment of the sleep surface, then the device complexity is reduced, but the pump lifespan becomes shorter than the bed lifespan, reducing overall utility
Solution Approach 1:
The single pump is segmented into multiple independent pumps (first pump and second pump). Each pump can operate independently to serve different pneumatic chambers, distributing the operational workload and extending individual pump lifespans while maintaining system functionality.
Solution Approach 2:
The system recovers pump capacity by allowing pumps to be cycled on and off based on demand. When one pump reaches wear thresholds, the system can switch to using other pumps, effectively recovering system functionality and extending overall pump array lifespan beyond what a single pump could achieve.
2Area of stationary object
If the air pump is located in close proximity to the sleep area, then space utilization is improved, but noise and vibrations increase, negatively impacting sleep quality
Solution Approach 1:
The pump system is segmented into multiple distributed pumps rather than one centralized pump. This allows individual pumps to be positioned in locations that balance proximity to sleep areas with noise considerations, as each pump serves specific zones and can be independently placed.
Solution Approach 2:
Multiple pumps are merged into a coordinated system where they work together to provide pneumatic adjustment. This merged system achieves the space efficiency of centralized control while distributing noise sources, allowing pumps to be positioned optimally regarding both proximity and noise exposure.
3Speed
If all pumps are operated simultaneously to provide pneumatic effects, then the response speed and firmness adjustment capability are improved, but the wear on each pump increases, reducing overall system reliability
Solution Approach 1:
The pump system employs periodic action by cycling pumps on and off based on operational needs and wear thresholds. Instead of continuous operation, pumps are activated periodically to achieve firmness adjustments, then rested to minimize wear accumulation, balancing speed requirements with reliability.
Solution Approach 2:
The system discards the notion of continuous pump operation and recovers pump life through strategic cycling. By monitoring wear thresholds and switching between pumps, the system maintains the ability to provide rapid firmness adjustments while recovering pump capacity through reduced individual usage time.
4Reliability
If the pump operates continuously to maintain sleep surface firmness, then the support quality is improved, but the noise exposure to the sleeper increases, degrading sleep quality
Solution Approach 1:
Instead of continuous operation, the pump system uses periodic action to maintain sleep surface firmness. Pumps are activated only when pressure adjustments are needed, then remain dormant, providing support quality maintenance while dramatically reducing noise exposure to sleepers during rest periods.
Solution Approach 2:
The system uses feedback from pressure sensors to determine when pump operation is needed. By continuously monitoring sleep surface pressure and only activating pumps when adjustments are required, the system maintains support quality while minimizing noise exposure through demand-based operation rather than continuous running.
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 solution provides improved sleep quality by dynamically adjusting firmness and support, extending pump lifespan, and reducing noise and vibrations, thus enhancing both the quality and duration of sleep.
Implementation Method 1
The air pressure may be provided by an air pump, for example. Operation of an air pump in close proximity to a sleep area may pose difficulties, however.
Implementation Method 2
The air pump may generate noise and/or vibrations during operation, noise and vibrations that may have a negative impact on quality and quantity of sleep.
