Innovation Solution
A device with a frame and suction pad for secure attachment, featuring two winding pulleys and one guide pulley with intersecting central axes, and spacing elements to guide the cutting wire, ensuring a safe cutting angle and preventing damage, with the ability to wind the wire from both ends for efficient cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cutting wire device is used to remove glasses from vehicle bodies, then the glass can be released from the bonding agent, but the cutting wire may cut into the vehicle body or glass causing damage
Solution Approach 1:
The patent introduces guide grooves as intermediary structures that channel and constrain the cutting wire's path. These grooves act as mediators between the cutting wire and the glass/vehicle body, ensuring the wire follows a safe trajectory that releases the glass without damaging surrounding structures.
Solution Approach 2:
The device uses the glass frame itself as part of the cutting path definition. The guide grooves are positioned to utilize the natural geometry of the glass frame, allowing the cutting wire to follow the frame's contour while releasing the bonding agent, thus the glass structure serves its own protective function.
2Adaptability or versatility
If the device is designed for small-sized glasses only, then it can fit the glass area, but it cannot handle glasses of different sizes and shapes
Solution Approach 1:
The device is designed with a universal fastening system that can accommodate glasses of various sizes and shapes. The fastening elements and guide groove configuration allow the same device to be adapted to different glass geometries, making it a multi-functional tool for various vehicle glass types.
Solution Approach 2:
The device incorporates adjustable or flexible positioning mechanisms that allow dynamic adaptation to different glass configurations. The fastening system can be adjusted during operation to match the specific geometry of the glass being removed, enabling precise positioning regardless of glass size or shape.
3Reliability
If the cutting wire is fastened to the glass by mere attachment, then the device structure is simple, but the cutting wire may loosen causing safety hazards
Solution Approach 1:
The cutting wire is pre-fastened to the device structure before the cutting operation begins. The guide grooves and fastening elements are positioned and secured in advance, ensuring the wire maintains proper tension and positioning throughout the cutting process without risk of loosening.
Solution Approach 2:
The device incorporates redundant fastening features and guide structures that provide backup containment for the cutting wire. Even if one fastening point experiences stress, the additional guide grooves and structural elements prevent wire loosening, providing a safety margin against wire detachment.
4Object-affected harmful factors
If the device requires moving additional guide elements during operation, then the cutting can be performed safely, but the work time increases and handling becomes complex
Solution Approach 1:
The guide structure is segmented into fixed guide grooves that are pre-positioned on the device body. These stationary guides divide the cutting path into manageable sections, each with its own guide feature, allowing the wire to be directed safely through the entire circumference without requiring movement of guide elements during operation.
Solution Approach 2:
The device structure itself provides the guiding function through integrated guide grooves that are permanently formed on the device body. The device does not require external or movable guide elements - the guiding function is built into the device's own structure, eliminating the need for additional handling operations.
