Removable Blade Knife System With Flexing Tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing knives do not offer a convenient and secure method for selectively removing and replacing blades, which can lead to inefficiencies and safety concerns when using different blades for various tasks.
Innovation Solution
A knife system comprising a blade support with a handle and a blade carrier, along with a blade tool that includes a compartment for receiving the blade, allowing for the blade to be flexed for connection and disconnection from the blade support, and a blade holder to prevent the blade from moving with the support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the blade is made resiliently flexible to enable connection and disconnection, then the ease of operation is improved, but the reliability deteriorates due to potential accidental movement
Solution Approach 1:
The blade is designed with resilient flexibility, allowing it to bend slightly during connection and disconnection operations. This flexibility enables the blade to be easily manipulated for mounting and removal while maintaining sufficient rigidity during normal use through the blade holder's securing mechanism
Solution Approach 2:
The blade holder serves as an intermediary component between the user and the blade. It provides a secure mounting interface that prevents accidental blade movement during use, while still allowing controlled flexing for intentional connection and disconnection operations
2Productivity
If the blade carrier is designed for quick release, then the productivity is improved, but the device complexity increases due to additional components
Solution Approach 1:
The blade carrier is segmented into distinct functional components: a mounting portion that interfaces with the blade connector, and a release mechanism portion. This segmentation allows for quick blade interchange while keeping each component relatively simple in design
Solution Approach 2:
The blade carrier incorporates a self-release mechanism that utilizes the resilient flexibility of the blade itself to automatically disengage the blade connector when the blade is flexed. This eliminates the need for complex external release tools or mechanisms

AI summary
A knife system including a blade, a blade support, and a blade tool. The blade includes a cutting edge, a blade connector, and a blade holder opening. The blade support includes a handle and a blade carrier. The blade carrier releasably connects to the blade connector to mount the blade to the blade support. The blade tool includes a blade tool compartment that receives the blade. The blade tool is able to flex the blade to enable the blade carrier to connect to the blade connector to mount the blade to the blade support and to disconnect from the blade connector to separate the blade and the blade support. The blade tool includes a blade holder receivable in the blade holder opening of the blade to prevent the blade from moving with the blade support when the blade carrier is connected to and disconnected from the blade.
