Solution Overview

Problem

Existing methods for mounting a leap block on eyeglass lenses are inconvenient and prone to user errors, such as incorrect orientation and adhesive contamination, due to the narrow mounting space and reliance on manual alignment.

Innovation Solution

A leap block mounting device that uses magnetic coupling and automated alignment to ensure the leap block is mounted in the correct direction automatically, minimizing user intervention and adhesive contact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual alignment method is used to mount leap block, then user can control mounting direction, but mounting space is narrow and user error is prone

Engineering Contradiction:
Improvemounting operationVSAvoidmounting direction accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The leap block mounting device enables automatic self-alignment through magnetic coupling. The leap block is automatically attracted to the mounting unit in the correct orientation without requiring manual alignment, making the system self-servicing and eliminating user error in direction control.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the manual mechanical alignment system with a magnetic field-based system. The magnetic coupling between the leap block and mounting unit automatically orients the leap block correctly, substituting human manual operation with a magnetic field mechanism.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of manufacture

If manual mounting from below to above is used, then leap block can be fixed, but adhesive portion adheres to hands and strength deteriorates

Engineering Contradiction:
Improvemounting processVSAvoidadhesive strength
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The patent inverts the traditional mounting direction by approaching the leap block from above rather than from below. The mounting unit descends from above to engage with the leap block, preventing adhesive contact with user hands while maintaining secure fixation.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The magnetic coupling acts as an intermediary mechanism that secures the leap block before adhesive application. The magnetic force holds the leap block in position during the adhesive setting process, preventing premature displacement while avoiding direct hand contact with the adhesive portion.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Manufacturing precision

If stand with directional fitting is used, then leap block mounting direction is controlled, but custom-made components are required

Engineering Contradiction:
Improvemounting direction controlVSAvoidcomponent customization
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The magnetic coupling mechanism provides universal applicability for leap block mounting. The same magnetic mounting unit can accommodate leap blocks of different orientations and positions without requiring custom-made components, as the magnetic field automatically provides the necessary directional control.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent changes the mounting control parameter from mechanical geometric constraints (requiring custom stands) to magnetic field parameters. By adjusting magnetic field strength and distribution, the system achieves precise directional control using standard components rather than custom-made parts.

Inventive Principle:
Principle #35Parameter changes

AI summary

Disclosed is a device and method for mounting a leap block capable of automatically adjusting the mounting direction of the leap block. The leap block mounting device comprises: a block stand (70) fixedly mounted to one end of a blocking device frame (10) and configured to support a leap block (5) so that the leap block (5) is rotatable in a horizontal direction; the leap block (5) in which a support (82) rotatably supported by the block stand (70) is formed in the center, and a first magnetic body (84) is mounted in one direction; and a leap block mounting unit (30) to which a second magnetic body (38) that couples with the first magnetic body (84) by magnetic force is mounted in one direction, and which rotates in the horizontal direction and couples with the leap block (5) in a fixed direction.
