Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current method of applying Exterior Insulated Finish Systems (EIFS) is labor-intensive, temperature-dependent, and lacks standardization, leading to increased costs, installation time, and potential system failures due to poor detailing at joints and penetrations, with window retrofits causing tenant disturbance and inefficiencies.
Innovation Solution
A robotic-assisted system using a data capture device with LiDAR, photo, and thermal imaging sensors to map building features, automate panel layout, and install window cassettes from the exterior, enabling precise cutting and fastening of large format foam insulation boards, reducing installation time and material costs, and minimizing tenant disruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If small format EPS foam boards are used to accommodate shipping and distribution, then material delivery is simplified, but installation time and material costs increase due to the need for individual scribing and multiple trips to the job site
Solution Approach 1:
The system segments the installation process into three distinct phases: data capture and mapping, panel fabrication, and robotic installation. This segmentation allows each phase to be optimized independently, with panels pre-fabricated to exact specifications before robotic installation, eliminating on-site scribing and reducing installation time.
Solution Approach 2:
The system performs preliminary actions by capturing building data and fabricating panels before installation. LiDAR and sensor data are collected to create precise 3D maps, and panels are pre-cut and prepared according to the mapped specifications, so that during installation, robots simply need to position and attach pre-prepared panels rather than scribing and fitting each one individually.
2Adaptability or versatility
If traditional manual scribing and attachment methods are used, then adaptability to façade variances is maintained, but installation precision and consistency deteriorate due to labor intensity and temperature constraints
Solution Approach 1:
The system incorporates continuous feedback loops where LiDAR and sensors capture building data, this data feeds into the panel fabrication process, and the fabricated panels are then installed by robots with sensors that provide feedback on positioning accuracy. This closed-loop feedback ensures both adaptability to façade variances and high installation precision.
Solution Approach 2:
The system replaces manual mechanical scribing and attachment operations with automated robotic systems guided by 3D mapped data. Robots equipped with sensors and control systems perform the installation tasks that were previously done manually, providing consistent precision不受 temperature constraints and eliminating human variability in the process.
3Ease of operation
If adhesive attachment is used for insulation boards, then ease of installation is improved, but installation season is limited to March through October due to minimum temperature requirements
Solution Approach 1:
The system replaces chemical adhesive attachment with mechanical robotic attachment systems. Robots use mechanical fastening mechanisms that do not rely on temperature-dependent chemical curing, thereby eliminating the seasonal installation constraints while maintaining ease of installation through automated positioning and securing of panels.
4Ease of operation
If window retrofits are performed from the interior of the building, then installation accessibility is improved, but tenant disturbance and energy efficiency deteriorate due to work disruption and potential asbestos/lead remediation requirements
Solution Approach 1:
The system inverts the traditional window retrofit approach by performing all window installation work from the exterior of the building rather than the interior. This allows workers to access windows from the outside, eliminating the need to disrupt tenants inside the building while still being able to install replacement windows and improve energy efficiency.
