Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electric mowers have a single power supply that cannot be adjusted, failing to meet the diverse operational requirements of users.
Innovation Solution
An electric mower equipped with a hybrid power system combining DC and AC power supplies, a handle adjusting mechanism with a hinge pin and compressed spring, and a back grass discharging device with an adjustable rod structure, allowing for flexible power usage and operation customization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single power supply is used in the electric mower, then the device complexity is reduced, but the adaptability to different user needs deteriorates
Solution Approach 1:
The electric mower is designed with a hybrid power system that can accept both AC power input and DC battery pack input, allowing the single device to function in multiple power modes. The control circuit automatically detects and switches between power sources, enabling the mower to adapt to different user needs (indoor/outdoor use, extended operation requirements) without requiring separate devices for each scenario.
2Ease of operation
If the handle structure is fixed, then the device complexity is reduced, but the ease of operation for different users deteriorates
Solution Approach 1:
The handle assembly incorporates an adjustable height mechanism with a hinge pin and compressed spring system that allows the upper handle to be positioned at multiple heights. Users can easily adjust the handle height by pressing a release button that disengages the hinge pin from gear holes, allowing the spring to push the hinge pin into different positioning holes corresponding to different handle heights. This dynamic adjustment capability accommodates users of different statures while maintaining operational control.
3Adaptability or versatility
If the back grass discharging device has a fixed structure, then the device complexity is reduced, but the adaptability to different discharge needs deteriorates
Solution Approach 1:
The back grass discharging device features an adjustable angle mechanism where the back cover plate can be rotated to different angles using an adjustment rod with stretchable structure. The adjustment rod can be extended or retracted to change the discharge angle, allowing grass to be discharged at different directions based on terrain and user preference. This dynamic adjustment provides versatility in grass discharge while maintaining a relatively simple mechanical structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The hybrid power system and adjustable handle mechanism enable the electric mower to adapt to different user needs, providing versatile power supply options and improved usability, while the adjustable back grass discharging mechanism optimizes grass collection based on user preference.
Implementation Method 1
a hinge pin and a compressed spring, wherein the hinge pin is inserted into the gear hole under the action of the compressed spring
Implementation Method 2
a drive block is provided between the button and the hinge pin, a tapered wedge surface is provided on the drive block, and the button and the tapered wedge surface act to drive the disengagement of the hinge pin from the gear hole
