Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heating devices for cutting laminated glass panels of different widths are inefficient, leading to energy wastage and prolonged heating times due to the use of emitters that extend over the entire width, even when processing smaller panels, and are limited by current and voltage restrictions.
Innovation Solution
An emitter system comprising multiple elongated emitters arranged along a common longitudinal axis, with angled ends to protect power connections and allow independent control, emitting shortwave infrared radiation to heat and cut laminated glass panels, using a glass cutting device that can adjust power density and emitter activation based on panel width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional heating devices extend over the entire width of the glass cutting bench, then the entire emitter can be used for heating, but energy is wasted when processing smaller formats and heating time increases
Solution Approach 1:
The emitter system is divided into multiple independent emitter segments arranged along a common longitudinal axis. Each segment can be independently controlled and switched on or off based on the width of the glass panel being processed. This segmentation allows the system to use only the necessary number of emitters for each specific task, eliminating energy waste from activating the entire emitter length for smaller panels while maintaining sufficient heating capacity for larger formats.
2Reliability
If the entire emitter length is switched on for all panel sizes, then consistent heating coverage is achieved, but heat energy and heating up time are lost for smaller formats
Solution Approach 1:
The emitter system incorporates dynamic control capabilities where the number of active emitter segments can be adjusted in real-time based on the detected width of the glass panel. The control unit receives width information and dynamically activates only the necessary number of emitters, ensuring optimal heating consistency for each panel size while minimizing heating time by avoiding unnecessary activation of excess emitters.
3Loss of time
If current density is increased to shorten irradiation duration, then heating time is reduced, but current and voltage restrictions limit the maximum achievable current density
Solution Approach 1:
By segmenting the emitter system into multiple independent units, the patent enables concentrated power delivery to fewer active segments. This allows the system to achieve higher effective current density at the target area by distributing total power across multiple segments, where each active segment operates at optimal current density within electrical restrictions, thereby reducing overall irradiation duration without exceeding voltage and current limits.
4Adaptability or versatility
If emitters are arranged to cover the full width, then all panel widths can be processed, but power connections are exposed to heat and emitter life is reduced
Solution Approach 1:
The emitter segments are designed with asymmetric angular orientation of their ends relative to the common longitudinal axis. This asymmetric arrangement strategically positions the power connections away from the direct path of infrared radiation and heat zones. The angled configuration allows heat to be directed toward the glass panel while power connections remain in cooler regions, reducing thermal stress on electrical components and extending emitter operational life while maintaining full width processing capability.
