Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mechanical coupling methods are used to join laminations, then structural strength is achieved, but manufacturing efficiency is reduced and costs increase
Solution Approach 1:
The patent replaces mechanical coupling methods with an adhesive-based system. An adhesive applicator delivers adhesive through passages in a support structure, allowing laminations to be joined chemically rather than mechanically. This substitution eliminates complex mechanical fasteners and assembly steps, thereby improving manufacturing efficiency and reducing device complexity.
Solution Approach 2:
The adhesive delivery system utilizes pressurized air to propel adhesive through passages in the support structure. This pneumatic mechanism enables controlled adhesive application without complex mechanical pumping systems, improving manufacturing efficiency while maintaining simplicity.
2Ease of manufacture
If adhesive application systems are implemented, then manufacturing costs are reduced, but system complexity increases
Solution Approach 1:
The support structure serves multiple functions: it provides structural support for the laminations and simultaneously acts as an adhesive delivery system with integrated passages. This multi-functionality reduces the need for separate adhesive application equipment, thereby lowering manufacturing costs without significantly increasing system complexity.
Solution Approach 2:
The adhesive applicator system is designed to be self-contained, with the support structure's passages serving as both structural elements and adhesive conduits. The system uses readily available pressurized air for adhesive propulsion, eliminating the need for specialized pumping mechanisms and reducing overall system complexity.

AI summary
An adhesive applicator for applying adhesive to a lamination of a core of an electric motor has a first substrate having an adhesive flow passage for conveying adhesive and an air flow passage for conveying pressurized air, a second substrate having a second substrate passage, and a slider having a slider passage. The slider is between the first and second substrates and moves between first and second positions. In the first position, the slider passage receives adhesive from the adhesive flow passage. In the second position, pressurized air from the air flow passage propels adhesive out of the slider passage, into the second substrate passage, out of the second substrate passage, and onto the lamination of the core.
