Post Driver and Puller with Gripping Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional post handling equipment is inefficient and time-consuming, as it requires switching between different implements for driving and pulling posts, and often results in larger holes than needed, with safety hazards from augers striking stones.
Innovation Solution
A compact post driving and pulling system with a base frame, gripping apparatus, and driver apparatus that can grip and impact posts without switching tools, utilizing a pinching member and pivot assemblies for both functions, mounted on a mobile base for ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a post hole digger with auger is used to form holes, then holes can be formed in the ground, but the device becomes difficult and dangerous to use when stones are struck, and the auger stops turning causing the rest of the digger to turn instead
Solution Approach 1:
The patent removes the auger component entirely and replaces it with a post driver that drives posts directly into the ground. This extraction of the problematic auger eliminates the safety hazards associated with stone strikes while maintaining the ability to form holes and install posts.
Solution Approach 2:
The post driver is designed to perform multiple functions: forming holes, driving posts, and pulling posts out. This multi-functional design eliminates the need for separate tools for each task, improving ease of use while maintaining safety through a unified, controlled operation system.
2Ease of operation
If a post hole digger is mounted on a vehicle, then movement between post locations is eased, but the device still cannot move the post to the hole location or help place the post in the hole
Solution Approach 1:
The patent combines the post driver, gripping apparatus, and pulling mechanism into a single integrated system mounted on a vehicle. This merging allows the vehicle to perform all post installation tasks (hole formation, post driving, and removal) without switching tools, dramatically improving productivity while maintaining ease of movement between locations.
Solution Approach 2:
The vehicle-mounted system is designed to perform multiple functions: forming holes, driving posts into the ground, and pulling posts out. This universal design eliminates the need for multiple separate tools and operations, enabling faster post installation while maintaining the ability to move freely between post locations.
3Quantity of substance
If the hole created by the auger is larger in diameter than the post, then the hole can accommodate the post, but the hole must be backfilled with soil and the soil tamped after the post is inserted
Solution Approach 1:
The patent changes the parameter of hole size by using a post driver with a smaller, post-specific bit that creates a hole size matching the post diameter. This parameter change eliminates the need for backfilling and tamping operations, reducing the time required for post installation while ensuring proper fit and stability.
4Adaptability or versatility
If conventional post handling equipment is used, then posts can be driven and pulled, but switching between different implements is required for different tasks
Solution Approach 1:
The patent designs a universal post handling system that can drive, pull, and form holes using a single integrated apparatus. The gripping apparatus and driver mechanism are configured to handle all post installation tasks, eliminating the need to switch between different implements and reducing overall operation time while maintaining full task capability.
Solution Approach 2:
The patent merges the post driver, gripping apparatus, and pulling mechanism into a single integrated system. This combining of functions allows the operator to perform all post handling tasks without switching tools, improving efficiency and reducing the time loss associated with tool changes while maintaining adaptability to different post installation scenarios.
