Innovation Solution
A method of manufacturing the apparatus involves measuring electrical properties before and after mechanical manipulation of the heater to detect damage, allowing for the rejection of damaged heaters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If mechanical manipulation is performed on the heater during manufacture, then the heater can be formed into the desired configuration, but the heater may be damaged during manipulation
Solution Approach 1:
The patent applies preliminary action by measuring the electrical property of the heater before mechanical manipulation (first measurement) and after mechanical manipulation (second measurement). This allows damage to be detected early in the manufacturing process, before the damaged heater is assembled into the final apparatus, preventing wasted assembly time and ensuring only functional heaters are installed.
Solution Approach 2:
The patent replaces mechanical inspection methods with electrical measurement to detect heater damage. Instead of visually inspecting or mechanically testing the heater for damage, the invention uses electrical property measurements (such as resistance) to detect whether the heater has been damaged during mechanical manipulation, providing a more sensitive and efficient detection method.
2Productivity
If damaged heaters are not detected, then manufacturing proceeds quickly, but the apparatus will have performance failures
Solution Approach 1:
The heater performs self-inspection through its electrical property measurements. The heater's own electrical characteristics (resistance, conductivity) serve as the indicator of its integrity. By measuring these intrinsic properties before and after manipulation, the system uses the heater's own attributes to detect damage without requiring external complex testing equipment or procedures.
Solution Approach 2:
The patent implements feedback by comparing the first measured value (before manipulation) with the second measured value (after manipulation). This comparison provides feedback on whether damage occurred during the manufacturing process. If the electrical property changes beyond acceptable thresholds, the system receives feedback that the heater is damaged and should be rejected, allowing corrective action before final assembly.

AI summary
A method of manufacture of an aerosol generating apparatus is described. The aerosol generating apparatus includes an electric heater. The method includes performing a first measurement of an electrical property of the heater in a first physical configuration to obtain a first measured value. Mechanically manipulating the heater into a second physical configuration. Performing a second measurement of the electrical property of the heater after mechanically manipulating the heater to obtain a second measured value. Based on a comparison of the first measured value and the second measured value, a determination of the heater having been damaged during the mechanical manipulation is made. Heaters damaged during manufacture can thus be rejected during the manufacture process.
