Door Handle Assembly with Interchangeable Lever and Auxiliary Battery Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional door locks with electronic keypads face issues when batteries run low, making the keypad inoperable, and asymmetric door handles require complex swapping and partial disassembly for orientation changes, complicating user access and maintenance.
Innovation Solution
A door handle assembly with interchangeable handles and auxiliary battery terminals located on the keypad face for easy temporary power access, featuring spring-biased pins for secure handle attachment and quick swapping, allowing flexible orientation and easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If asymmetric door handles are used to provide directional functionality, then the door lock provides proper directional operation, but the handle requires complex swapping and partial disassembly for orientation changes
Solution Approach 1:
The door handle assembly is divided into separable components: a handle body and a handle lever that can be detached and reattached. The lever can be removed from one side and installed on the other side of the door without disassembling the entire handle assembly, enabling easy orientation changes while maintaining directional functionality.
Solution Approach 2:
The handle lever is designed to be dynamically reconfigurable between different orientations. A release mechanism allows the lever to be detached from its mounting position and reattached to the opposite side of the door, providing adaptability for different installation scenarios without permanent fixed orientation.
2Adaptability or versatility
If electronic keypads are used to provide modern access control, then the door lock offers code-based unlocking, but the keypad becomes inoperable when batteries run low
Solution Approach 1:
The door lock system accepts variable power source parameters by providing both battery-powered and manual operation modes. When battery power becomes insufficient, the system can transition to manual key operation or alternative power sources, maintaining functionality across different power conditions and ensuring continuous operability.

AI summary
A door handle assembly that allows for easy removal and switching of handles. Such an arrangement may provide the flexibility to change handle orientation and interchange handles based on a user's circumstances or preferences such as when a door handle is configured as a lever having a curved shape. Further, the door handle may be configured as a door lock having a keypad access control. The face of the keypad accessible from outside the door may include auxiliary battery terminals to provide the user with easy accessibility for providing temporary power to the door lock with an auxiliary battery should the installed batteries housed within the door lock fail to provide sufficient power.
