Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If resin composition is applied using conventional applicators, then the application process can be completed, but the time required for application is excessive and process tact time is increased
Solution Approach 1:
The applicator is divided into distinct functional segments: a cartridge part for resin storage, a mixer part for combining resin components, and an application part for dispensing. This segmentation allows each part to be optimized independently, with the mixer part continuously preparing resin for application, thereby increasing overall application speed and reducing idle time.
Solution Approach 2:
The mixer part performs preliminary mixing of resin components before they reach the application point. By continuously mixing resin in advance within the mixer part, the system ensures ready-to-apply resin is always available at the discharge end, eliminating waiting time and maintaining continuous high-speed application.
2Ease of operation
If resin composition is applied using conventional applicators, then the application can proceed, but the applicator is vulnerable to impact and shaking during the process
Solution Approach 1:
The discharge part is designed with a storage space that acts as a buffer between the mixer part and the application point. This storage space cushions against impact and shaking by providing a reservoir that can absorb sudden movements or pressure changes, protecting the mixing mechanism and ensuring consistent resin flow despite external disturbances.
Solution Approach 2:
The storage space in the discharge part serves as an intermediary between the mixer part and the application environment. It isolates the sensitive mixing mechanism from external impacts and shaking, allowing the mixer to operate smoothly while the storage space absorbs and dampens external disturbances before they reach the application point.
3Productivity
If resin composition is applied quickly to reduce process tact time, then productivity improves, but the quality of resin application may be compromised
Solution Approach 1:
The mixer part continuously mixes resin components throughout the application process, ensuring that high-quality, well-mixed resin is constantly supplied to the application point. This continuous mixing action maintains resin homogeneity and application quality even at high speeds, eliminating the need to slow down for periodic mixing cycles.
Solution Approach 2:
Resin components are mixed in advance in the mixer part before reaching the application point. This preliminary mixing ensures that resin is fully prepared and homogeneous before application begins, allowing high-speed dispensing without compromising mixing quality or resin uniformity.

AI summary
A resin composition applicator for applying a resin composition to at least one surface of a housing or to at least a part of at least one surface of the battery is provided. The resin composition applicator includes a cartridge unit, a mixer unit connected to the cartridge unit, and an application unit connected to the mixer unit. The application unit includes at least one application pipe provided such that the resin composition introduced from the mixer unit can pass therethrough, and a discharge unit having a storage space provided such that the resin composition introduced from the at least one application pipe is accumulated therein. The discharge unit may at least include a first surface and a second surface for forming the storage space, and be configured such that the resin composition is discharged through a space between one end of the first surface spaced apart from one end of the second surface.
