Wire Rope Insulation Cover Lifting for Large Bathtubs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large heat insulation covers for bathtubs and swimming pools are difficult for one person to open due to increased weight, as they become bigger with social development.
Innovation Solution
A bathtub heat insulation cover system pulled up and down by a wire rope, featuring a lifting crossbar mechanism with guide grooves, a middle crossbar with a driving motor and pulleys, and a chain or belt transmission mechanism for synchronized movement, allowing for easy operation with a control switch or remote control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the heat insulation cover becomes larger to cover bigger bathtubs and swimming pools, then the heat insulation area is improved, but the weight increases making it difficult for one person to open
Solution Approach 1:
The patent replaces the traditional manual mechanical lifting system with an automated wire rope hoisting mechanism. The hoisting mechanism uses a wire rope wrapped around a drum, driven by a motor, to automatically lift the heavy heat insulation cover. This substitution of mechanical manual operation with an automated motor-driven system resolves the contradiction by enabling easy operation (single-person control) while maintaining large cover area.
2Area of stationary object
If the heat insulation cover becomes larger, then the heat insulation area is improved, but the weight increases requiring more lifting force
Solution Approach 1:
The patent replaces manual lifting force with a motor-driven wire rope hoisting mechanism. The motor provides the necessary lifting force through the drum and wire rope system, eliminating the need for human physical effort. This allows the system to handle large, heavy covers without increasing the operational force requirement on the user's part.
Solution Approach 2:
The wire rope acts as an intermediary between the motor and the heat insulation cover. The wire rope transmits the lifting force from the motor-driven drum to the cover, enabling force transmission over a distance and through a mechanical advantage system. This intermediary mechanism allows the motor to provide sufficient lifting force for large covers.
3Ease of operation
If a wire rope hoisting mechanism is introduced to enable easy opening, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent introduces a motor-driven wire rope hoisting mechanism to replace manual lifting, improving ease of operation. While this does increase device complexity, the complexity is concentrated in a dedicated hoisting subsystem rather than the entire system, allowing the rest of the cover structure to remain relatively simple.
