An adhesive force confirmation device with a configuration that includes an attaching portion with a reference surface and working surfaces designed for easy peeling of electrodes, featuring curved or stepped surfaces and optional confirmation units for measuring peeling, such as transparent scales or sensors, to assess adhesive strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a thermostatic bath is used to maintain high-temperature and high-humidity environment for evaluating adhesive force, then the evaluation accuracy is improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The patent extracts the essential evaluation function from the complex thermostatic bath environment. Instead of requiring controlled temperature and humidity conditions, the invention uses a simple attaching portion with reference and working surfaces that can be used in any environment. The evaluation is reduced to attaching the electrode to the working surface and observing peeling behavior, eliminating the need for specialized environmental control equipment.
Solution Approach 2:
The attaching portion is designed to automatically indicate adhesive force status through visual observation of peeling. The electrode either peels easily from the working surface or remains attached, providing self-evident feedback without requiring complex measurement instruments or environmental controls. This self-service mechanism allows users to evaluate adhesive force simply by observation.
2Reliability
If a thermostatic bath is used for adhesive force evaluation, then the measurement reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The invention extracts the core evaluation capability from the complex thermostatic bath system, retaining only the essential function of comparing adhesive force between reference and working surfaces. This simplified approach maintains reliability through consistent surface design while dramatically improving ease of operation by eliminating environmental control requirements and complex procedures.
Solution Approach 2:
The system provides automatic visual feedback through the peeling behavior of the electrode on the working surface. Users simply attach the electrode and observe whether it peels easily or remains firmly attached, providing reliable evaluation without requiring operation of complex equipment or interpretation of complex data.
3Ease of operation
If the working surface is designed for easy peeling, then the ease of operation is improved, but the measurement precision may deteriorate
Solution Approach 1:
The working surface is designed with specific local properties - a curved shape that facilitates easy peeling observation while the reference surface maintains different properties for consistent attachment. This local quality differentiation allows the working surface to be easily peeled for observation while the reference surface provides reliable baseline attachment, maintaining measurement precision through controlled local characteristics rather than uniform design.
Solution Approach 2:
The working surface incorporates a curved shape that introduces a geometric dimension to facilitate peeling. This curvature creates a natural peeling path and visual indicator, making it easy to observe whether peeling has occurred while maintaining the ability to precisely measure adhesive force through the presence or absence of peeling at the curved surface.

AI summary
An adhesive force confirmation device is a device that confirms adhesive force of an electrode and is to be used for an electrical treatment device and includes an attaching portion to which an adhesive portion included in the electrode is attachable. The attaching portion includes a reference surface and working surfaces connected to the reference surface. The action surfaces are configured such that in a state where the adhesive portion is attached to the action surfaces, the adhesive portion is easily peeled off from sides of the action surfaces farther from the reference surface than from sides of the action surfaces closer to the reference surface.
