Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing riding mowing devices require manual key operation, which is inconvenient and lacks the advanced keyless start systems found in automobiles, due to differences in power systems.
Innovation Solution
A keyless start system for riding mowing devices, incorporating an authentication module and controller that allows smart unlocking and locking, using smart keys with communication technologies like Bluetooth or NFC, and biometric or speech recognition for secure operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual key system is used for starting the riding mowing device, then the device can be operated, but the operation process becomes tedious and inconvenient
Solution Approach 1:
The patent replaces the mechanical key system with an electronic authentication system. The controller authenticates user identity through electronic means (password, fingerprint, or facial recognition) and automatically controls the power supply assembly, eliminating the need for manual key insertion and removal. This substitution of mechanical operation with electronic automation directly resolves the contradiction by improving ease of operation while reducing time loss.
2Ease of operation
If a keyless start system from automobiles is applied to riding mowing devices, then operation convenience is improved, but the system becomes too complicated for the mowing device's power system
Solution Approach 1:
The patent extracts only the essential authentication and control functions from complex automobile keyless systems. It implements a simplified version using basic authentication modules (password input, fingerprint sensor, or facial recognition camera) directly integrated with the mowing device's existing controller and power supply assembly. This extraction approach provides keyless operation convenience while avoiding the unnecessary complexity of full automobile keyless systems.
Solution Approach 2:
The patent adapts the authentication system to match the specific parameters and capabilities of riding mowing devices. Instead of using complex multi-factor authentication systems designed for automobiles, it implements authentication methods appropriate for the simpler power system of mowing devices, adjusting the system complexity to match the application requirements.
3Reliability
If traditional manual key operation is used, then the system structure remains simple, but user experience and security are insufficient
Solution Approach 1:
The patent replaces the simple mechanical key system with electronic authentication mechanisms that provide enhanced security. The controller can authenticate users through passwords, fingerprint recognition, or facial recognition, and automatically control power supply. This substitution improves reliability and anti-theft security while maintaining manageable system complexity through integrated electronic control.
Solution Approach 2:
The patent introduces an authentication module as an intermediary between the user and the power supply system. This intermediary verifies user identity through various methods (password, fingerprint, facial recognition) before authorizing operation. The intermediary approach enhances security and reliability while keeping the overall system structure organized and manageable through clear separation of authentication and power control functions.

AI summary
A riding mowing device includes a keyless start system which allows a user to start the riding mowing device without a key. The keyless start system includes an authentication module and a controller. The authentication module is configured to authenticate the validity of a smart key of the user. The controller is electrically connected to at least the power supply assembly, where the controller controls the riding mowing device to switch from a locked mode to an unlocked mode after the validity authentication of the smart key succeeds. In the locked mode, the riding mowing device cannot walk or perform a mowing function, and in the unlocked mode, the riding mowing device can walk or perform the mowing function.
