Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component tape handling systems struggle to accommodate variations in component tape size and mechanical properties, leading to issues such as jamming, inadequate creasing, and increased machine downtime due to rigid frame designs that cannot adjust to different tape geometries and elasticities.
Innovation Solution
A mechanism featuring a floating frame with a flexible coupling to a base, equipped with springs and fasteners that allow linear translation and rotation, enabling controlled pressure application to both knife and creasing regions, thereby adapting to variations in tape thickness and geometry, ensuring consistent creasing and preventing jamming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid frame design is used, then structural stability is improved, but adaptability to different tape geometries deteriorates
Solution Approach 1:
The frame is transformed from a rigid static structure to a dynamic flexible structure that can adapt its shape. The flexible coupling allows the frame to deflect and adjust its position automatically in response to variations in tape thickness and geometry, resolving the contradiction between structural stability and adaptability.
Solution Approach 2:
The mechanical properties of the frame are changed by introducing flexibility through the flexible coupling. This allows the frame to change its physical state from rigid to compliant, enabling it to accommodate different tape geometries while maintaining operational stability through controlled deflection.
2Ease of manufacture
If a rigid frame design is used, then manufacturing simplicity is improved, but reliability in handling varied tapes deteriorates
Solution Approach 1:
The frame is transformed from a rigid static structure to a dynamic flexible structure that can adapt its shape. The flexible coupling allows the frame to deflect and adjust its position automatically in response to variations in tape thickness and geometry, resolving the contradiction between structural stability and adaptability.
Solution Approach 2:
The mechanical properties of the frame are changed by introducing flexibility through the flexible coupling. This allows the frame to change its physical state from rigid to compliant, enabling it to accommodate different tape geometries while maintaining operational stability through controlled deflection.

AI summary
A mechanism comprising a base having a top surface and including a groove extending along the top surface and a frame flexibly coupled to the base. The frame includes a right side attached to a left side. The right side has a substantially “L-shaped” cross-section and includes a knife portion and a creasing portion. The left side includes a substantially “L-shaped” cross-section and is rigidly coupled to the right side such that the frame has a substantially “U-shaped” cross-section that is sized to receive at least a portion of the base. A first spring is positioned proximate the knife portion and is arranged to control a compressive force between the knife portion and the base and a second spring is positioned proximate the creasing portion and is arranged to control a compressive force between the creasing portion and the base.
