Universal Frame Tongue for Quick Implement Changeover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing land prep and maintenance equipment for small-scale applications is either expensive, poorly constructed, or limited in functionality, making it impractical for non-commercial users, and lacks a universal frame for easy implement changeover.
Innovation Solution
A universal frame system designed for small tractors or ATVs that allows for quick and robust attachment of multiple implements, featuring a tongue element with adjustable hitch and lifting mechanism, enabling cost-effective and versatile land preparation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate implements are purchased for different land prep and maintenance tasks, then functionality and versatility are improved, but cost of ownership and device complexity increase
Solution Approach 1:
The patent implements a universal frame system with a standardized tongue assembly featuring multiple hole patterns that can accommodate various implements including tillers, seeders, and trailers. This single frame structure replaces the need for multiple separate equipment purchases, providing versatile land preparation and maintenance capabilities while reducing overall cost of ownership.
Solution Approach 2:
The implement system is divided into separable components: a universal frame with standardized connection points and interchangeable implements. Each implement can be independently attached or detached via the saddle and bolt mechanism, allowing users to select only the functionality needed for specific tasks rather than owning complete separate equipment for each function.
2Quantity of substance
If a universal frame system is implemented to reduce cost of ownership, then cost efficiency is improved, but the complexity of the connection mechanism may worsen
Solution Approach 1:
The tongue assembly incorporates multiple pre-drilled hole patterns at specific locations to accommodate different implement types. The saddle feature includes corresponding mounting holes that align with specific tongue holes depending on the implement configuration. This localized variation in hole placement provides adaptability without requiring complex adjustable mechanisms, maintaining connection simplicity while enabling versatility.
3Strength
If robust and rigid connections are made between frame and implements, then connection strength is improved, but the time required for implement changeover may worsen
Solution Approach 1:
The tongue assembly is pre-configured with multiple hole patterns during manufacturing, and the saddle feature includes pre-positioned mounting holes. When changing implements, users simply need to align the saddle with the appropriate pre-drilled holes and insert bolts, eliminating the need for drilling or complex alignment procedures. This preliminary preparation of connection points maintains strong rigid connections while enabling quick implement changes.

AI summary
A small-scale land prep and maintenance equipment system includes a universal frame with a tongue element that includes an implement connection point (such as a through-hole or threaded hole) configured for receiving a saddle and bolt aspect of an implement. Advantageously, the implement connection point of the universal frame and the saddle of the implement provide for a robust and rigid connection between the universal frame and an implement while also enabling quick changeover of landscaping implements. Moreover, because the universal frame may be used on any number of implements, the cost of an integrated frame in each implement is avoided.
