Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for constructing tall buildings are inefficient and hazardous, requiring significant time and resources for supporting structural assemblies, leading to increased costs and safety risks due to the need for large cranes and manual labor at height.
Innovation Solution
The use of a locking device apparatus that automatically engages with recessed pockets in the building core, allowing for secure and efficient support of structural assemblies through vertical rotation, eliminating the need for cranes and manual labor at height, and incorporating a fire protection water supply system, temporary carrier beams, façade mounting solutions, deflection control, and strand protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing support methods are used to support structural assemblies, then structural support is provided, but significant time and resources are required, resulting in increased construction costs
Solution Approach 1:
The locking device is designed to automatically engage with the building core structure without requiring manual intervention. The device self-activates through gravitational force when the structural assembly is raised to the correct elevation, eliminating the need for workers to manually operate support mechanisms at height.
Solution Approach 2:
The patent replaces complex manual mechanical support systems with an automated locking mechanism that uses gravitational force and mechanical engagement with pre-installed pockets in the building core, significantly reducing the time and resources required for support operations.
2Reliability
If existing support methods are used to support structural assemblies, then structural support is provided, but the methods lead to structural damage or safety hazards
Solution Approach 1:
The locking device automatically engages and secures the structural assembly to the building core without requiring workers to manually position or secure components at height, eliminating safety hazards associated with manual labor in elevated positions.
Solution Approach 2:
The locking device is designed as a temporary support mechanism that is discarded after use, replacing expensive and hazardous permanent support structures. This disposable nature allows for optimized design focused purely on safety and functionality during the critical support phase.
3Ease of operation
If manual labor at height is used to secure structural components, then structural assemblies can be secured, but safety risks increase
Solution Approach 1:
The locking device performs the securing operation automatically through gravitational activation, completely eliminating the need for workers to perform manual operations at height and thereby removing the associated safety risks.
Solution Approach 2:
The patent replaces manual mechanical operations with an automated gravitational mechanism that securely engages the locking device with the building core, maintaining ease of operation while dramatically improving safety by removing human workers from hazardous elevated positions.
4Speed
If large cranes are used to raise structural assemblies, then structural assemblies can be lifted, but construction costs and complexity increase
Solution Approach 1:
The patent extracts the heavy crane equipment from the construction process by implementing a counterweight system that is integrated directly into the locking device. This allows structural assemblies to be raised using much lighter equipment while maintaining the necessary lifting capability through the counterbalance mechanism.
Solution Approach 2:
The locking device incorporates a counterweight mechanism that balances the weight of the structural assembly during raising operations, eliminating the need for large cranes. The counterweight system provides mechanical advantage, allowing lightweight equipment to lift heavy loads efficiently.

AI summary
Embodiments are directed to a lock for securing a structural assembly having a primary beam for constructing a core-supported high-rise building, and a building core wall defining an outer face. The lock includes a fixed bracket that couples to the primary beam of the structural assembly, a structural pin, a moveable component connected to the fixed bracket by the structural pin, and a recessed pocket embedded in the building core wall. The moveable component defines a bearing surface that contacts the outer face of the building core wall during the raising of the structural assembly. The recessed pocket receives the moveable component of the locking device when the structural assembly reaches one of the predetermined positions. The moveable component automatically engages with and disengages from the recessed pocket as the structural assembly rises, enabling temporary support and securement of the structural assembly at the predetermined positions during construction.
