Customizable Telescopic Shovel with Button-Actuated Length Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shovels have fixed sizes, making them inconvenient for users who need to accommodate different tasks, as they require multiple shovels for various applications, and are difficult to transport due to their size and weight.
Innovation Solution
A customizable shovel with a telescopic assembly that allows adjustment of the shaft length using adjustment buttons, a removable blade, and a handle assembly for ease of use and storage, along with a locking mechanism for secure attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size shovel is used, then the structure is simple and easy to manufacture, but it cannot accommodate different task requirements and requires multiple shovels
Solution Approach 1:
The shovel shaft is divided into multiple telescopic sections that can be independently adjusted. The shaft includes a first shaft section, second shaft section, third shaft section, and fourth shaft section, each capable of relative movement to provide different length configurations for different task requirements.
Solution Approach 2:
The shovel employs dynamic adjustment mechanisms including telescopic sections with expansion joints, adjustable angle joints between shaft sections, and a blade that can be rotated and tilted relative to the shaft. These dynamic features allow the shovel to adapt its configuration based on task requirements.
2Adaptability or versatility
If a large-sized shovel is used to accommodate different tasks, then versatility is improved, but portability and ease of transport deteriorate
Solution Approach 1:
The telescopic shaft sections are nested within each other, with the second shaft section disposed within the first shaft section, the third within the second, and the fourth within the third. This nesting arrangement allows the shovel to be compacted to a minimal length for easy portability while maintaining full extension capability for various tasks.
Solution Approach 2:
The shovel employs dynamic adjustment mechanisms including telescopic sections with expansion joints, adjustable angle joints between shaft sections, and a blade that can be rotated and tilted relative to the shaft. These dynamic features allow the shovel to adapt its configuration based on task requirements.
3Adaptability or versatility
If multiple shovels are purchased to accommodate different needs, then task-specific performance is improved, but the number of items to transport increases
Solution Approach 1:
The shovel is designed as a universal tool that can perform multiple functions through its adjustable features. The telescopic shaft, adjustable angle joints, and removable blade configurations enable a single shovel to replace multiple fixed-function shovels, accommodating various task requirements from digging to scraping to snow removal.
Solution Approach 2:
The shovel employs dynamic adjustment mechanisms including telescopic sections with expansion joints, adjustable angle joints between shaft sections, and a blade that can be rotated and tilted relative to the shaft. These dynamic features allow the shovel to adapt its configuration based on task requirements.
4Adaptability or versatility
If a telescopic assembly with adjustment mechanisms is added, then adjustability and portability are improved, but device complexity increases
Solution Approach 1:
The shovel shaft is divided into multiple telescopic sections that can be independently adjusted. The shaft includes a first shaft section, second shaft section, third shaft section, and fourth shaft section, each capable of relative movement to provide different length configurations for different task requirements.
Solution Approach 2:
The telescopic shaft sections are nested within each other, with the second shaft section disposed within the first shaft section, the third within the second, and the fourth within the third. This nesting arrangement allows the shovel to be compacted to a minimal length for easy portability while maintaining full extension capability for various tasks.
