Building Escape Structure With Elastic Footboards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current escape equipment is often complex to operate, has low transportation efficiency, and is unsuitable for large buildings, leading to potential threats during emergencies like fires, especially due to its design flaws and inability to facilitate quick, safe, and simultaneous multi-floor escapes without specialized skills or tools.
Innovation Solution
An escape structure featuring two slide bars mounted on a building's external wall, surrounded by a cover unit with footboard units providing elastic cushioning, allowing individuals to slide down safely and quickly, without requiring special skills or tools, and enabling simultaneous multi-floor escapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional escape equipment is used, then escape function is provided, but operation is excessively complicated and requires special skills
Solution Approach 1:
The escape structure is divided into independent modular units: slide bars for descent, foot board units with elastic bodies for cushioning, and surround cover units for protection. Each module performs a specific function, allowing simple assembly and operation without requiring complex coordination or special skills from users.
Solution Approach 2:
The elastic bodies in the foot board units automatically provide cushioning protection when stepped on during descent, without requiring manual activation or adjustment by the user. The structure utilizes the user's own weight and motion to engage the protective mechanisms, eliminating the need for special operational knowledge.
2Productivity
If conventional escape equipment is used, then escape function is provided, but transportation efficiency is very low and escape is slow
Solution Approach 1:
The foot board units are arranged at periodic intervals along the slide bars, providing regular cushioning points during descent. This periodic arrangement allows users to maintain continuous contact with support surfaces, enabling faster and more efficient descent compared to continuous friction or infrequent support points.
Solution Approach 2:
The elastic bodies in the foot board units dynamically change their compression state based on the user's weight and descent speed, automatically adjusting the cushioning force. This parameter adaptation allows optimized descent speed while maintaining safety, improving overall transportation efficiency without requiring manual adjustment.
3Reliability
If conventional escape equipment is used, then escape function is provided, but structure is not perfect and may become useless for buildings of relatively large heights
Solution Approach 1:
The escape structure uses multiple modular foot board units distributed along the slide bars, with each unit providing independent cushioning protection. This segmentation ensures that even for very tall buildings, users receive frequent protective support points, maintaining reliability regardless of total descent distance.
Solution Approach 2:
The elastic bodies in the foot board units are pre-installed and positioned along the slide bars at optimal intervals. Before the user begins descent, these cushioning elements are already in place and will automatically engage at the appropriate moments, ensuring protection is provided beforehand without requiring real-time adjustment during emergency escape from great heights.
4Ease of operation
If conventional escape equipment is used, then escape function is provided, but operation cannot be properly carried out due to panic
Solution Approach 1:
The escape structure requires minimal user input beyond basic movement. The slide bars guide descent automatically, and the foot board units with elastic bodies provide passive cushioning that engages automatically when stepped on. This self-service mechanism eliminates complex manual operations that could fail under panic conditions, allowing reliable operation even when users are frightened or inexperienced.
Applied Scientific Principles
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 solution ensures high mobility, quick and safe descent, allows multiple persons to escape synchronously, reduces fear, and prevents falling, making it accessible to the weak, with a simple structure that doesn't require special tools or complex arrangements, and can be used for self-rescue and assisting others.
Implementation Method 1
the foot board units allow the feet of the escaping person to stand thereon to thereby achieve an effect of elastic cushioning
Implementation Method 2
an escaping person moves into the escape space, and then follows the two slide bars to slide down

AI summary
An escape structure is applied to an external wall of a building and includes at least two slide bars, a plurality of foot board units, and a surround cover unit. The slide bars are mounted to the external wall of the building, and the two slide bars are spaced from each other by a distance. The plurality of foot board units are mounted to the slide bars, and the foot board units are arranged on the two slide bars in an alternate manner. The surround cover unit surrounds the slide bars to form an escape space. When a disaster (fire) occurs, an escaping person enters the escape space to follow the two slide bars to slide down in an alternate manner, and the foot board units receive the feet of the escaping person to stand thereon and provides an elastic cushioning effect.
