Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liftable beds in recreational vehicles face issues with suboptimal space utilization, complex wiring, high manufacturing costs, and aesthetic concerns due to visible wiring connections to the service battery.
Innovation Solution
A liftable bed design with integrated battery and movement means on the base, using belts and a transmission shaft for motion, eliminating the need for external wiring and allowing independent operation, with optional wireless actuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wiring is installed to connect the bed motor to the service battery, then the bed can be powered and operated, but space usage is reduced and aesthetics are degraded due to visible wiring
Solution Approach 1:
The battery and motor are merged into a single integrated assembly that is mounted directly on the bed base. This combination eliminates the need for separate wiring connections to the service battery, as the integrated battery provides power directly to the motor, thereby freeing up space and removing visible wiring from the recreational vehicle interior.
Solution Approach 2:
The integrated battery assembly acts as an intermediary between the power source and the motor, providing a self-contained power unit that eliminates the need for external wiring infrastructure. This intermediary solution resolves the contradiction by providing operational capability without requiring space-consuming wiring connections.
2Ease of operation
If wiring is installed to connect the bed motor to the service battery, then the bed can be powered and operated, but manufacturing costs increase and installation complexity increases
Solution Approach 1:
The battery and motor are merged into a single integrated assembly that is mounted directly on the bed base. This combination eliminates the need for separate wiring connections to the service battery, as the integrated battery provides power directly to the motor, thereby freeing up space and removing visible wiring from the recreational vehicle interior.
Solution Approach 2:
The integrated battery-motor assembly is self-contained and self-sufficient, requiring no external wiring infrastructure or complex installation procedures. The assembly comes pre-configured with all necessary electrical connections internal to the unit, making installation straightforward and reducing manufacturing complexity.
3Ease of operation
If wiring is installed to connect the bed motor to the service battery, then the bed can be powered and operated, but aesthetics are degraded due to visible wiring
Solution Approach 1:
The battery and motor are merged into a single integrated assembly that is mounted directly on the bed base. This combination eliminates the need for separate wiring connections to the service battery, as the integrated battery provides power directly to the motor, thereby freeing up space and removing visible wiring from the recreational vehicle interior.
Solution Approach 2:
The wiring infrastructure is extracted and removed from the system by using an self-contained integrated battery-motor assembly that requires no external wiring connections. This extraction eliminates the aesthetic problem of visible wiring while maintaining full operational capability.
