Mower Deck Trimmer Bracket with Height and Length Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lawn mower and tractor deck-mountable trimmer solutions lack adjustability, ease of maintenance, and storage, requiring additional time, effort, and separate equipment to edge areas inaccessible to the mower, and are often costly or not available for existing mowers.
Innovation Solution
A mower deck-mountable trimmer attachment with a two-section bracket system allowing height and length adjustment, featuring a hinge for easy access and storage, and electrical connectivity with safety features like a spring attachment and fuse for secure operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed deck-mountable trimmer is used, then the structure is simple, but the adjustability for different deck heights and extension lengths is poor
Solution Approach 1:
The bracket is designed with adjustable features allowing dynamic reconfiguration. Multiple adjustment mechanisms including height adjustment along the side wall, extension length adjustment via radially distributed bores, and rotational adjustment enable the structure to adapt to different operational requirements while maintaining a relatively simple overall design
Solution Approach 2:
The single bracket structure serves multiple functions: it provides structural support, enables height adjustment for different deck configurations, allows extension length variation, and facilitates rotational positioning. This multi-functionality reduces the need for multiple separate components while achieving high adaptability
2Ease of operation
If a rigid fixed-length bracket is used, then the manufacturing is simple, but the ease of adjustment for maintenance and storage is poor
Solution Approach 1:
The bracket is segmented into adjustable sections with distinct adjustment mechanisms. The height adjustment section, extension length adjustment section, and rotational section are separated into functional zones, each with its own adjustment features (slots, bores, pins), allowing independent adjustment without disassembling the entire structure
Solution Approach 2:
The bracket incorporates dynamic adjustment capabilities through multiple mechanisms: height adjustment via slots or bores along the side wall, extension length adjustment through radially distributed bores, and rotational adjustment. These dynamic features enable easy reconfiguration for maintenance access and storage while maintaining manufacturing feasibility through standardized adjustment components
3Length of moving object
If the trimmer extends far from the deck, then the cutting area is increased, but the stability and control become difficult
Solution Approach 1:
The trimmer extension length is made dynamically adjustable through radially distributed bores in the bracket. Users can select different extension lengths based on operational needs, allowing optimization between cutting area coverage and stability/control. The adjustable nature enables the system to adapt to different ground conditions and operational requirements
4Adaptability or versatility
If multiple adjustment mechanisms are added, then the versatility is improved, but the device complexity increases
Solution Approach 1:
The bracket design integrates multiple adjustment functions into a unified structure. Height adjustment, extension length adjustment, and rotational adjustment are incorporated as integrated features of the single bracket rather than separate mechanisms, reducing the overall number of components while maintaining high versatility
Solution Approach 2:
Multiple adjustment mechanisms are merged into the bracket structure. The height adjustment slots/bores, extension length bores, and rotational features are combined in a single bracket component, eliminating the need for separate adjustment devices and reducing overall system complexity
