Solution Overview
Problem
Existing connectors for devices like joysticks and cell phones fail to provide a robust yet easily removable connection, often resulting in damage during transport or increased theft risk due to cumbersome disconnection methods.
Innovation Solution
A quick release connector system featuring a mount plate with alignment notches, a latch cog with mount tabs, a release lever with a spring mechanism, and a top mount with coupling feet, allowing for secure attachment and easy detachment of devices without requiring tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If robust connection methods such as screws or threaded connectors are used, then connection strength is improved, but removal complexity increases requiring tools or multiple steps
Solution Approach 1:
The connector is divided into separate functional components: a mounting surface with alignment features, a removable device with corresponding alignment features, and a latch mechanism with a release lever. This segmentation allows the connection to be robust when engaged while enabling simple one-handed release by actuating the lever, resolving the contradiction between strong connection and easy removal.
Solution Approach 2:
The latch cog with spring-loaded lever acts as an intermediary mechanism between the mounting surface and removable device. It provides robust mechanical retention through the latch engagement while allowing quick release through the lever action that disengages the latch, eliminating the need for tools and simplifying the removal process.
2Adaptability or versatility
If frequent disconnecting is required for devices like cell phones, then adaptability is improved, but connection robustness deteriorates due to wear or accidental detachment
Solution Approach 1:
The connector transitions from a static fixed connection to a dynamic controllable connection. The spring-loaded latch mechanism allows the connection state to change easily between engaged and disengaged positions through lever actuation, enabling frequent safe disconnecting while maintaining robust connection during use through the reliable latch engagement.
3Ease of operation
If alignment features are added to enable quick connection, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The alignment features use asymmetric geometric shapes (such as shaped apertures and corresponding shaped portions) that guide the removable device into proper orientation during attachment. This asymmetric design enables intuitive alignment without complex adjustment mechanisms, achieving quick and accurate positioning while adding minimal structural complexity.

AI summary
A quick release connector for coupling a removable device with a mounting surface. The mounting surface can include a wheelchair arm, and the removable device can include a user controller. The quick release connector can enable a user to briefly contact a release mechanism, rotate the removable device by a limited amount, and remove the device with a single hand. The quick release connector can robustly couple the removable device with the mounting surface, enabling the mounted removable device to resist dislodging by knocks and bumps.
