Mower Slope Portion Attachment Mechanism
Solution Overview
Problem
The existing configuration of mid-mount mowers requires complex and labor-intensive operations for attaching and detaching slope portions, which can be prone to detachment due to vibration during use.
Innovation Solution
A mower design featuring passage portions with front and back slope portions that can be easily attached and detached using holding portions and a disengaging operation tool, allowing for simultaneous operation of both slope portions in the same direction, and incorporating an urging member for automatic engagement, enhancing operational simplicity and strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the slope portion is attached and detached manually through complex operations, then the structural design can be simpler, but the operability and ease of attachment/detachment deteriorates
Solution Approach 1:
The patent combines the attachment and detachment operations for both slope portions into a single integrated operation. The holding portions are positioned and structured such that one simultaneous operation can engage or disengage both slope portions together, reducing the number of separate manual operations required and improving ease of attachment/detachment
Solution Approach 2:
The holding portions are designed to automatically engage with the slope portions when the holding member is operated, eliminating the need for complex manual alignment or multiple adjustment steps. The structure allows the system to self-engage through a simple operating motion
2Reliability
If the holding portion is designed to firmly hold the slope portion, then the reliability improves, but the ease of detachment deteriorates
Solution Approach 1:
The holding portion employs a dynamic engagement mechanism where the holding member can be operated to simultaneously change the engagement state of both slope portions. The holding portions are positioned to allow a single operating motion to release both engagements at once, making detachment as easy as attachment while maintaining firm holding during operation
Solution Approach 2:
The holding system is segmented into multiple holding portions that are independently positioned but collectively operated. Each holding portion can engage its corresponding slope portion firmly, but all can be released simultaneously through one operating action on the holding member, balancing reliability with ease of detachment

AI summary
There are included front and back slope portions attachable to and detachable from storage positions and use positions, front and back holding portions capable of engaging with engagement portions of the front and back slope portions as attached to the storage positions and holding the front and back slope portions at the storage positions, and a disengaging operation tool capable of being manually operated to a disengaging position at which the front holding portion and the back holding portion are releasable from the engagement portions of the front and back slope portions and at which the slope portions are detachable from the storage positions.
