Electronic Doorframe with Cable Diverter for Retrofitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic door frames lack flexibility in installation and retrofitting, as wiring must be completed before installation and sealed with masonry, making it difficult to add or change electronic hardware post-installation.
Innovation Solution
A system that allows for post-installation cabling and connection of electronic features within the door frame, using a hollow body structure with spring clips and spacers for securement, and ports and diverters for guiding cables, enabling easy retrofitting and integration of new electronic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wiring is completed before door frame installation and sealed with masonry, then structural integrity and security are improved, but flexibility for future hardware changes deteriorates
Solution Approach 1:
The door frame system is divided into modular components: the main frame structure, removable access panels, and separate electronic hardware modules. This segmentation allows the frame to remain structurally intact while enabling easy access to internal wiring and components through removable panels, resolving the contradiction between structural integrity and adaptability.
Solution Approach 2:
Conduit pathways and cable routing channels are pre-installed within the frame structure during manufacturing, but actual wiring connections are designed to be made after installation through accessible panels. This preliminary preparation of pathways without completing all wiring beforehand allows both structural security and future flexibility.
2Stability of the object's composition
If door frame is sealed with masonry after installation, then security and stability are improved, but ease of cabling and retrofitting deteriorates
Solution Approach 1:
Removable access panels serve as intermediaries between the external environment and the internal wiring spaces. These panels provide a controlled access point that maintains the sealed masonry structure while enabling cable installation and hardware retrofitting without breaking the seal or compromising stability.
Solution Approach 2:
The access panels are designed to nest within the frame structure when closed, maintaining the external appearance and structural integrity of the sealed frame. When opened, they provide access to nested internal compartments containing wiring channels and electronic components, enabling easy cabling operations.
3Manufacturing precision
If conduit and cabling are installed in factory before shipping, then manufacturing precision is improved, but adaptability at installation site deteriorates
Solution Approach 1:
The system separates fixed infrastructure elements (conduit pathways, mounting brackets, frame structure) that are precision-manufactured in the factory from flexible connection elements (cable routing, electronic hardware configuration) that can be adapted on-site. This segmentation maintains manufacturing precision for critical components while preserving site adaptability.
Solution Approach 2:
The system incorporates dynamic, adjustable elements such as reconfigurable cable management features, adjustable mounting positions, and flexible cable routing options within the pre-installed conduit system. This allows the statically precision-manufactured frame to accommodate dynamically changing site requirements.

AI summary
A system for providing electronic features in a doorframe includes a body structure having a top wall, a bottom wall and a plurality of side walls. The walls define an interior space of the body structure. A plurality of ports are formed in the top wall and a plurality of ports are formed in the bottom wall with each port opening into the interior space. One or more of the top wall ports is longitudinally aligned with a respective bottom wall port to form a port pair. A diverter is positioned in the interior space and extends in the interior space from one side wall and toward an opposing side wall. The diverter spans between the port pair. The diverter has a diverter surface that is configured for directing an element that extends through a port of the port pair toward an area in the body structure.
