Stabilizer bracket for electronic device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing e-poll book systems face connection instability between the encoder and tablet due to repeated stress from voter access card insertions, leading to potential disconnection and system failure.
Innovation Solution
A stabilizer bracket is designed to provide stability between the encoder and tablet, featuring a pocket-like structure with rear and front tabs to secure the encoder, a beveled slot for voter access cards, and a power cord passage, ensuring secure mounting and easy access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the encoder and tablet are connected only through the dock connector port, then the setup is simple and easy to assemble, but the connection becomes unstable and prone to disconnection due to repeated stress from card insertions
Solution Approach 1:
The bracket is divided into multiple functional segments: a main body portion that cradles the encoder, rear tabs that engage with the tablet, front tabs that provide additional support, and a slot for card insertion. This segmentation allows each part to perform its specific function while collectively providing a stable connection between the encoder and tablet.
Solution Approach 2:
The bracket acts as an intermediary component between the encoder and tablet. Instead of the encoder connecting directly to the tablet through the dock connector port alone, the bracket provides an additional structural intermediary that distributes mechanical stress and prevents direct transmission of forces from card insertions to the electrical connector.
2Reliability
If the encoder is securely mounted to prevent disconnection, then connection reliability improves, but the device complexity increases due to additional mounting components
Solution Approach 1:
The bracket combines multiple functions into a single integrated component: it provides structural support for the encoder, engages with the tablet through rear tabs, guides card insertion through the slot, and protects the dock connector port. By merging these functions into one piece, the design achieves reliable mounting without proportionally increasing complexity.
Solution Approach 2:
The bracket serves multiple purposes simultaneously: it acts as a mounting structure, a stress distributor, a card guide, and a connector protector. This multi-functionality reduces the need for separate components for each function, thereby limiting the increase in overall device complexity while achieving secure mounting.
3Ease of operation
If the encoder slot is directly accessible, then card insertion is easy and quick, but repeated insertions cause stress and wear on the connector connection
Solution Approach 1:
The bracket's slot serves as an intermediary structure that guides the card insertion process. The slot is positioned and shaped to direct the card toward the encoder slot, providing ease of insertion while the bracket's rigid structure absorbs and distributes the mechanical stress, preventing direct transmission of insertion forces to the electrical connector between the encoder and tablet.
Data Source
AI summary
A device that stabilizes the connection between the encoder and the tablet of an e-poll book system is provided. The device prevents disconnection of the encoder and/or wear on the connectors between the encoder and tablet that can result in failure of the system. The stabilizer bracket includes a first, primary opening or pocket that is sized to receive the body of the encoder therein and includes an opening that allows the user to see and encoder indicator light on the front face of the encoder 20. A pair of tabs extend from the rear face of the stabilizing bracket, and a shorter pair of tabs extend from the front face of the stabilizing bracket to provide stability.
