E-Throttle Switch Block Radial Housing Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand throttle twist grip designs face challenges in accommodating necessary components like sensors and switches within the limited installation space near the rotary handle, compromising operational safety and environmental protection.
Innovation Solution
The design separates the housing into upper and lower parts, with the magnet and sensor assembly in one part and the switch unit in another, allowing for sufficient space and protection, and includes a radial extension for the circuit board and cable harness with sealing for environmental protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If components are arranged in the axial direction of the twist grip, then the installation space is compact, but sufficient space cannot be provided for sensor, shield, and switch
Solution Approach 1:
The patent transitions from axial arrangement to radial arrangement of components. The sensor, shield, and switch are positioned radially around the rotary handle rather than sequentially along its axis, utilizing the circumferential space to achieve sufficient component accommodation while maintaining compact overall dimensions.
Solution Approach 2:
The housing is divided into multiple segments or sections, each accommodating specific components. This segmentation allows optimal positioning of the sensor, shield, and switch in different radial zones, providing sufficient space for each component while maintaining a compact overall structure.
2Reliability
If housing is divided into attachable parts, then assembly and sealing are improved, but device complexity increases
Solution Approach 1:
The housing is segmented into modular sections that can be separately assembled and sealed. This segmentation enables improved sealing at each interface while maintaining manufacturing simplicity through standardized connection elements.
