Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fully automated electric cutting machine is used, then cutting precision is improved, but device size and structural complexity increase, making it unsuitable for stores with limited space
Solution Approach 1:
The cutting machine is divided into independent functional modules: a cutting module with a circular saw blade, a positioning module with a scale and positioning block, and a control module. This segmentation allows each module to perform its specific function independently, reducing overall system complexity while maintaining automated cutting precision
Solution Approach 2:
The machine is designed with a universal positioning mechanism that can accommodate different window covering sizes and cutting requirements through a single scale and positioning block system, eliminating the need for multiple specialized machines or complex reconfiguration mechanisms
2Adaptability or versatility
If a fully automated electric cutting machine with multiple capabilities is designed, then adaptability to different window covering styles and sizes is improved, but device complexity and maintenance difficulty increase
Solution Approach 1:
The positioning block can be dynamically adjusted along the scale to different positions, and the cutting depth can be dynamically modified, allowing the same machine structure to adapt to various window covering styles and sizes without requiring complex reconfiguration mechanisms
Solution Approach 2:
The machine achieves adaptability through parameter changes rather than structural changes: adjusting the positioning block location on the scale and modifying cutting depth parameters allows the same physical apparatus to handle different window covering specifications, maintaining simplicity while improving versatility
3Extent of automation
If the motor drives transmission mechanisms to activate internal components, then automated operation is achieved, but activation time increases due to sequential movement
Solution Approach 1:
The heavy transmission mechanisms are extracted and replaced with direct manual operation for positioning, while only the cutting action itself is automated with an electric motor. This eliminates time-consuming transmission sequences while maintaining essential automation for the cutting operation
4Volume of moving object
If manual cutting is used, then device size is reduced, but cutting precision deteriorates due to reliance on user judgment
Solution Approach 1:
A scale and positioning block serve as intermediaries between the user and the cutting action. The user manually positions the block on the scale according to measurement requirements, and the scale provides precise reference markings, eliminating reliance on user judgment while keeping the device compact and simple

AI summary
A method of cutting a window covering includes providing a window covering cutting apparatus, and utilizing an input device thereof to receive a mounting mode, cutting size information and identification information of the window covering. A position detecting device detects a position of a limit assembly and generates a position detecting value correspondingly. A signal processing circuit generates adjusted position information and target position information according to received information and the position detecting value. A manual operating member is manually adjusted to move the limit assembly until the adjusted position information equals to the target position information. The signal processing circuit sets a cutting device to cut the window covering after it abuts against the limit assembly. The method obtains a correct cutting position of the window covering by calculation of the signal processing circuit, thereby reducing cutting errors in size of the window covering due to miscalculation by users.
