Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing saw blades are limited to two angular positions and have complex assemblies, making them inefficient for cutting tasks in constrained spaces and costly to produce.
Innovation Solution
An angle adjustable saw with a handle comprising a first and second cover body, a grip body, and a control assembly that includes a pivot component, elastic button, and limiting component, allowing the blade to be pivoted and folded to various angles by engaging a block with recesses on the clamping portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the saw blade is designed with only two angular positions (unfolded or folded), then the assembly is simple, but the adaptability to different cutting angles is limited
Solution Approach 1:
The blade is designed with a pivotable connection to the handle, allowing it to rotate dynamically between multiple angular positions (unfolded, folded, and intermediate angles). The pivot component enables continuous angle adjustment rather than fixed positions, while the limiting component with multiple limiting positions provides stable stopping points. This dynamic design resolves the contradiction by enabling versatile angle adaptation without requiring complex multi-position locking mechanisms.
Solution Approach 2:
The blade angle relative to the handle is made adjustable through the pivot component, allowing the user to change the angular parameter as needed. The elastic button and limiting component work together to maintain the blade at selected angles while permitting easy transitions. This parameter change capability provides multiple cutting angles without increasing assembly complexity, as the same pivot mechanism serves all angle positions.
2Adaptability or versatility
If the saw blade is designed with multiple angular positions, then the adaptability to constrained spaces is improved, but the production cost increases
Solution Approach 1:
The pivotable blade design with a single pivot component allows the blade to assume multiple angular positions naturally during rotation, eliminating the need for multiple discrete locking mechanisms for each angle. This dynamic approach reduces manufacturing complexity and cost compared to designing separate fixed-position mechanisms for each angle, while still providing the adaptability needed for constrained spaces.
Solution Approach 2:
The pivot component serves multiple functions simultaneously: it enables rotation to various angles, provides stopping positions through the limiting component, and allows easy angle changes via the elastic button. This multi-functionality reduces the total number of parts needed, simplifying manufacturing and reducing production costs while achieving versatile angle adjustment for different cutting scenarios.
3Adaptability or versatility
If the saw blade uses a complex assembly to achieve multiple angles, then the blade angle adjustment capability is improved, but the ease of operation deteriorates
Solution Approach 1:
The elastic button provides a simple, intuitive operation for angle adjustment. When pressed, it releases the limiting component, allowing the blade to rotate freely to the desired angle. When released, the limiting component automatically engages at one of the limiting positions, providing stable angle retention. This dynamic interaction between the elastic button and limiting component simplifies operation compared to complex multi-step locking mechanisms, making angle changes quick and easy while maintaining versatility.

AI summary
An angle adjustable saw includes a handle including a first cover body and a second cover body. One of two ends of the handle includes an opening. A space is formed in the handle and communicates with the opening, the first pivot hole and the adjustment hole. A blade includes a clamping portion inserted into the space of the handle through the opening, and being pivotably relative to the handle by a control assembly. Multiple protrusions are formed on a distal end of the clamping portion. Multiple recesses are formed between the protrusions. The control assembly includes an elastic button and a limiting component respectively connected to the first and second cover bodies of the handle. The limiting component has a block and is movable by pushing the elastic button to engage the block with one of the recesses of the clamping portion to set the blade at an angle.
