Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art jump-lift systems for high-rise buildings are complex and expensive, limiting the number of floors that can be serviced by the elevator and requiring intermediate platforms to prevent object and material fall, which complicates the construction process.
Innovation Solution
A self-climbing elevator machine room that integrates key functions, eliminating the need for intermediate platforms and allowing the elevator to operate with a reduced number of unserviced floors by using guide rails and hydraulic actuators to climb vertically, enabling early installation and reusability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If prior art jump-lift systems are used to increase hoisting height, then the elevator can service higher floors, but the system complexity and cost increase due to requiring special shaft interfaces and intermediate platforms
Solution Approach 1:
The elevator machine room is divided into modular segments that can be incrementally repositioned. The machine room comprises a first module and a second module that can be selectively positioned relative to each other, allowing the hoisting height to be increased in controlled steps without requiring complete system replacement or complex intermediate structures.
Solution Approach 2:
The elevator machine room is designed to be self-repositioning capability through integrated lifting mechanisms. The machine room can lift and reposition itself using its own drive mechanism and ropes, eliminating the need for external cranes or complex installation equipment, thereby reducing system complexity while achieving height extension.
2Length of stationary object
If prior art jump-lift systems are used, then higher floors can be reached, but intermediate platforms (crash decks) are required to prevent objects and materials from falling, increasing device complexity
Solution Approach 1:
The invention eliminates the need for intermediate crash decks by extracting this safety function and replacing it with a enclosed machine room design. The machine room acts as a protective enclosure that prevents objects and materials from falling into the shaft, removing the requirement for separate intermediate platform structures.
Solution Approach 2:
The safety function previously requiring separate intermediate platforms is merged into the machine room structure itself. The machine room serves dual purposes: housing the elevator machinery and providing safety containment to prevent object drop, thereby eliminating the need for additional intermediate platforms.
3Length of stationary object
If the elevator machine room is repositioned in steps, then the hoisting height can be increased, but special anchoring points must be provided beforehand in the shaft walls
Solution Approach 1:
The system transitions from static anchoring to dynamic self-repositioning. The machine room uses movable counterweights and adjustable rope lengths to dynamically adapt to different heights, eliminating the need for predetermined static anchoring points in the shaft walls. The counterweight can be positioned at different levels to balance the machine room during incremental repositioning.

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 self-climbing elevator machine room reduces construction complexity and costs by allowing early installation and operation across multiple floors without special shaft interfaces, enhancing flexibility and reducing unserviced floors, while being reusable across different construction sites.
Implementation Method 1
at least one lifting means (130) extending between the two decks (110, 120) for moving the two decks (110, 120) along the guide rails (25) in relation to each other
Data Source
AI summary
The self-climbing elevator machine room comprises two decks positioned upon each other. Each deck comprises guide means supporting the deck movably on guide rails and locking means locking and unlocking the deck to the guide rails and/or to guide rail fixing means. Lifting means move the two decks along the guide rails in relation to each other. At least one power source provides power to the lifting means. The elevator machine room climbs stepwise along the guide rails by alternatingly locking and unlocking the lower deck and the upper deck to the guide rails and/or to the guide rail fixing means and thereafter raising the unlocked deck.
