Electronic Deadbolt Installable Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic deadbolts face installation challenges due to pinched wires and aesthetic concerns related to their larger size compared to mechanical deadbolts, necessitating a compact and easily installable electronic deadbolt solution.
Innovation Solution
The electronic deadbolt assembly features a latch assembly with a bolt movable between extended and retracted positions, an exterior assembly with an electronic input device, and an interior assembly with an electronic control unit, including a gear train and an extendable electrical connector for easier installation, along with a compact design and user mode switching capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wiring harness is passed through a bore in the door for connection between exterior and interior assemblies, then electrical connection is achieved, but excess wires become pinched and installation becomes difficult
Solution Approach 1:
The electrical connector is pre-configured with an extended configuration that positions the wiring harness away from potential pinching zones before installation occurs. This preliminary positioning prevents wire pinching during the installation process while maintaining reliable electrical connection between assemblies.
2Adaptability or versatility
If electronic deadbolt components are made larger to accommodate electronic components, then electronic control functionality is achieved, but aesthetic appearance deteriorates due to larger size
Solution Approach 1:
The electrical connector utilizes an extended configuration in the dimensional space, allowing electronic components to be accommodated while maintaining a compact external profile. This dimensional arrangement enables electronic functionality without compromising aesthetic appearance.
3Ease of operation
If the electrical connector is extended for easier access during installation, then installation ease is improved, but device complexity increases
Solution Approach 1:
The electrical connector is segmented into distinct configuration states (extended and retracted), allowing it to adapt to different installation phases. This segmentation enables easy access during installation while maintaining a compact form when installed, balancing installation ease with device simplicity.
