Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inter-floor transport systems face limitations in accessing high floor heights due to maximum installation height constraints and the inability to arrange multiple boarding units within a single passage, necessitating a system that offers ease of installation, maintenance, and cost-effectiveness.
Innovation Solution
An inter-floor transport system utilizing an aerial vehicle that moves vertically and horizontally along a passage, powered by a contactless guide cable connected to a power supply, allowing the vehicle to receive power without direct contact, and supplemented by an onboard battery for horizontal movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a cable driving method is used, then the system can operate, but the maximum installation height is limited and high floor heights above a specific height cannot be accessed
Solution Approach 1:
The patent replaces the traditional cable-driven mechanical system with an aerial vehicle that moves autonomously along the passage. The aerial vehicle uses its own propulsion system (motors, propellers, or rotors) instead of being pulled by cables, eliminating the installation height limitations of cable systems and enabling access to any floor height.
Solution Approach 2:
The system transitions from a static cable infrastructure to a dynamic aerial vehicle that can move flexibly along the passage. The aerial vehicle can change its position, speed, and operational characteristics dynamically, allowing it to access high floor heights that would be impossible for fixed cable systems.
2Power
If components are connected with a belt, then power transmission is achieved, but multiple boarding units cannot be arranged within a single passage
Solution Approach 1:
The patent replaces the belt-connected mechanical power transmission system with wireless power transfer technology. The ground station transmits power wirelessly to multiple aerial vehicles simultaneously, eliminating the physical belt connection that would prevent multiple units from operating in the same passage. This enables high productivity with multiple boarding units.
Solution Approach 2:
The ground station is designed to provide universal power transmission capabilities to multiple aerial vehicles simultaneously. The wireless power transmission system can serve multiple boarding units within a single passage, making the system versatile and scalable for high-productivity applications.
3Use of energy by moving object
If traditional power transmission methods are used, then power can be supplied, but power loss occurs and dust and particle issues arise
Solution Approach 1:
The patent replaces traditional contact-based power transmission (such as sliding contacts or brush systems) with wireless power transfer technology. This eliminates physical contact between moving parts, preventing power loss due to friction, wear, and electrical resistance while also preventing dust and particle generation from mechanical contact.
4Adaptability or versatility
If existing inter-floor transport systems are used, then transport functionality is provided, but installation and maintenance are complex and costly
Solution Approach 1:
The system is segmented into independent modular components: the ground station and the aerial vehicles. Each aerial vehicle is a self-contained unit with its own propulsion, power reception, and control systems. This modular segmentation simplifies installation (each unit can be installed independently) and maintenance (individual vehicles can be serviced without affecting the entire system).
Solution Approach 2:
By replacing complex mechanical connections (cables, belts, contact-based power transmission) with wireless and autonomous systems, the patent reduces the number of moving parts and connection points that require installation and maintenance. The wireless power transfer and autonomous navigation eliminate the need for precise mechanical alignment and frequent maintenance of contact components.
