Asymmetric Handheld Controller with Flexible Strap Harness for EPMDs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional handheld controllers for electric personal mobility devices lack safety features, adaptability, and user-friendly design, posing challenges for rider safety and control, especially in visibility and interaction with various types of EPMDs.
Innovation Solution
A flexible strap harness assembly with adjustable length and perforations to secure various accessories, including headlights, taillights, horns, and mirrors, that conforms to asymmetrically shaped controllers, combined with a wireless module for enhanced functionality and connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional handheld controllers are used, then basic functionality is provided, but rider safety and adaptability are insufficient
Solution Approach 1:
The controller is designed with universal adaptability to work with different types of electric personal mobility devices (EPMDs) while incorporating multiple safety functions including headlights, taillights, horns, and brakes into a single integrated device, allowing one controller to serve multiple safety and control purposes across different EPMD platforms
Solution Approach 2:
The patent combines previously separate safety accessories (headlights, taillights, horns, brakes) and control functions into a single integrated handheld controller unit, merging multiple functions into one device that can be universally attached to different EPMD types
2Reliability
If basic handheld controllers are used, then simplicity is maintained, but safety features and user access are limited
Solution Approach 1:
The controller is divided into functional modules (lighting, horn, brake, control interfaces) that can be independently configured and attached to different EPMDs, allowing safety features to be segmented into manageable components while maintaining overall system integration
Solution Approach 2:
A single controller unit provides multiple safety functions (lighting, horn, brake, control) that would traditionally require separate devices, reducing the number of components users need to manage while enhancing safety capabilities
3Ease of operation
If fixed design controllers are used, then manufacturing is simplified, but ease of use and fitting to users are reduced
Solution Approach 1:
The controller incorporates adjustable and reconfigurable elements that allow users to customize the device for their specific EPMD and personal preferences, while the modular design enables flexible assembly and disassembly without requiring complex manufacturing processes
Solution Approach 2:
The controller allows users to adjust operational parameters such as light intensity, horn volume, and control sensitivity to suit different users and riding conditions, providing customization without requiring multiple fixed-design models

AI summary
An asymmetrically shaped handheld controller and harness assembly for securing safety accessories to the handheld controller for electric personal mobility devices (EPMDs), and a kit thereof, generally includes an asymmetrically shaped handheld controller, an adjustable and a flexible strap that is perforated along its length, releasable connectors that secure the flexible strap about the controller, and headlight and taillight assemblies. The flexible strap conforms to at least three sides of the controller and has an oblong aperture sized to allow access through the strap to a thumb control on the controller. Stabilizing side members may connect accessories including horns, bells, and mirrors to the flexible strap. The controller is configured to wirelessly connect to EPMDs. The taillight operates as a brake light.
