Blade Mounting Bracket With Strip-Shaped Hole And Grooves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blade replaceable knives have complex structures that complicate the process of disassembling and reassembling blades, leading to high manufacturing costs and safety concerns during blade replacement.
Innovation Solution
A blade mounting bracket with a strip-shaped hole featuring a mounting section and a tightening section, along with a simple unlocking mechanism using a reed and button, allows for easy blade replacement without direct contact with the cutting edge, ensuring user safety and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional blade replaceable knife structure with multiple gaskets and clamping nails is used, then blade replacement is facilitated, but the structure becomes complicated and manufacturing cost increases
Solution Approach 1:
The blade mounting bracket is divided into distinct functional sections: a mounting section with a strip-shaped hole for blade insertion, and a tightening section with grooves for securing the blade. This segmentation allows each part to perform its specific function independently, simplifying the overall structure while maintaining ease of blade replacement.
Solution Approach 2:
The blade mounting bracket is designed as a universal component that can accommodate different types of blades through the standardized strip-shaped hole configuration. The mounting section and tightening section work together to provide a multi-functional solution that handles both blade insertion and securing operations, reducing the need for multiple separate components.
2Ease of operation
If a traditional blade replaceable knife structure with multiple gaskets and clamping nails is used, then blade replacement is facilitated, but manufacturing cost increases
Solution Approach 1:
The mounting section and tightening section are merged into a single integrated blade mounting bracket component. This consolidation reduces the total number of parts that need to be manufactured, assembled, and inventoried, thereby lowering manufacturing costs while still providing the necessary functionality for easy blade replacement.
Solution Approach 2:
The universal blade mounting bracket design allows for standardized manufacturing processes that can be applied across different knife models. By creating a multi-functional component that handles both mounting and tightening operations, the invention reduces per-unit manufacturing costs through economies of scale and simplified production workflows.
3Object-affected harmful factors
If a simple unlocking mechanism with reed and button is used, then user safety is enhanced by avoiding direct contact with cutting edge, but the locking mechanism must still ensure blade stability
Solution Approach 1:
The reed and button mechanism serves as an intermediary system that allows users to operate the blade mounting bracket without directly contacting the cutting edge. The button presses against the reed, which in turn interacts with the blade or mounting bracket components to facilitate safe blade replacement while maintaining secure locking when engaged.
Solution Approach 2:
The locking mechanism is segmented into distinct functional elements: the button for user activation, the reed for force transmission and control, and the grooves for actual blade retention. This segmentation allows each component to be optimized for its specific function while working together to provide both safety and reliability.

AI summary
A blade mounting bracket includes a blade mounting part and a handle connecting part. A blade mounted on the blade mounting bracket defines a strip-shaped hole. The strip-shaped hole includes a mounting section and a tightening section. A width of the mounting section is greater than a width of the tightening section. The blade mounting part includes a base and a fixing piece connected with the base. An upper surface of the fixing piece is matched with the mounting section. An upper portion of the fixing piece extends downwards to connect with the base. Grooves are formed between the upper surface of the fixing piece and the base. The fixing piece includes a fixing block matched with the mounting section. The grooves and the fixing block fix the blade in a plane in which the blade is located.
