Lockable Multi-Axis Foot Switch for Selectable Pedal Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing foot switches require multiple designs to accommodate different operating modes, leading to inefficiencies and the need for suppliers to maintain multiple types of devices, whereas users often prefer switches that can operate in both single and multi-axis modes.
Innovation Solution
A foot switch design with a locking device that allows selective locking of pedal movement about one axis, enabling operation in both single and multi-axis modes, and includes a manually or remotely controllable locking mechanism with a sensor arrangement to detect the locking state, allowing users to switch between modes based on preference or application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a foot switch is designed with a pedal movable around multiple axes to provide multiple operating modes, then the adaptability and versatility of the device is improved, but the device complexity increases
Solution Approach 1:
The foot switch is designed with a pedal that can move around multiple axes (first axis for vertical movement, second axis for horizontal movement) to provide multiple operating modes. A locking device with locking pins can selectively lock the pedal in different positions to enable either single-axis or multi-axis operation, making the device universal and adaptable to different user preferences and applications without requiring multiple separate devices.
2Device complexity
If a foot switch is designed with a pedal movable around only one axis to simplify the structure, then the device complexity is reduced, but the adaptability and versatility deteriorate
Solution Approach 1:
The foot switch incorporates a locking device that can dynamically change the degree of freedom of the pedal. The locking pins can be positioned to lock the pedal around the first axis only (single-axis mode) or released to allow movement around both the first and second axes (multi-axis mode). This dynamic adjustment capability allows the device to adapt its complexity level based on the required operating mode, providing simplicity when needed while maintaining versatility when required.

AI summary
A foot switch includes at least one pedal rotationally mounted for actuating about at least two axes arranged at an angle with respect to each other. A stop device that can stop a movement of the pedal about one of the two axes is provided.
