Woven Wood Blind Cutting Machine Clamp Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machines are unable to accurately cut woven wood blinds without cracking or splintering, as they cannot securely hold blinds with varying stick diameters, leading to uneven cuts and damage.
Innovation Solution
A window covering cutting machine with a clamping mechanism using a hand screw, clamp block, and spring to securely hold the blind, along with rigid cutting support members and a cutting device, ensures accurate and damage-free cuts by maintaining the blind's stability during the cutting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If clamps are used to secure woven wood blinds in a cut-down machine, then the blinds can be held in place for cutting, but the blinds are difficult to clamp securely and can be easily damaged when clamped due to varying stick diameter and compression
Solution Approach 1:
The clamping force is distributed across multiple points along the blind rather than concentrated at a single location. The clamp mechanism applies pressure through segmented contact points that accommodate the varying diameters of individual sticks while distributing the clamping load to prevent localized damage or splitting.
Solution Approach 2:
The clamp design incorporates adjustable parameters including variable clamping pressure and adaptable contact surface geometry. This allows the clamping mechanism to accommodate different blind thicknesses and stick diameters while maintaining secure holding without exceeding the damage threshold of the woven wood material.
2Productivity
If a circular blade is used to cut the blind, then cutting can be performed, but the blade may not make even cuts or may crack or splinter the blind if the woven wood blind is not securely held
Solution Approach 1:
The blind is securely clamped in a fixed position before the cutting operation begins. This preliminary securing action prevents movement during cutting, ensuring that the circular blade follows a consistent cutting path and produces even cuts without causing cracks or splinters from blind displacement.
Solution Approach 2:
The cutting blade is positioned and aligned with the marked cutting line before the actual cutting motion is initiated. This preliminary positioning ensures that the blade engages the material at the correct location and maintains proper cutting geometry throughout the operation, resulting in precise and even cuts.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The machine effectively cuts woven wood blinds without cracking or splintering, providing accurate and even cuts, suitable for use in retail settings with minimal training, reducing poorly cut or damaged material.
Implementation Method 1
a spring between the hand screw and the clamp block. The spring is attached between the clamp block and the hand screw such that the spring is compressed when the clamp is moved to the clamping position and the spring expands when the clamp block is moved out of the clamping position
Data Source
AI summary
A method and machine for cutting woven wood blinds is disclosed. The disclosed machine can include a cutting mechanism, a support surface adjacent at least one opening in the cutting mechanism housing, a spring loaded clamp which engages the woven wood blind to hold the blind securely for cutting without damaging the blind. The clamp is preferably operated by a hand screw. An indicator such as a collar attached to the hand screw is provided to tell the user when the clamp is positioned to provide the desired pressure. The disclosed method can include positioning a window covering into a cutting machine, positioning a first cutting support member on the window covering, moving a clamp to engage the first cutting support member and cutting the window covering.
