Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If visual observation of expert movement is used for learning assistance, then the learner can observe and imitate the movement, but the learning efficiency is insufficient

Engineering Contradiction:

Improvelearning efficiencyVSAvoidtactile sensation information

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The system provides tactile feedback to the learner by generating force tactile sensations that replicate the expert's operational feelings. The operation controller compares the learner's operation with the expert's operation and provides corrective tactile feedback through the haptic device, enabling the learner to sense the differences and improve learning efficiency.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The haptic device serves as an intermediary that translates the expert's operational parameters into tactile sensations that the learner can perceive. Instead of directly transmitting physical contact, the system uses the haptic device to mediate the transfer of tactile information between the expert's operation and the learner's experience.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If only visual information is provided to the learner, then the system is simple to operate, but the learning assistance is not efficient

Engineering Contradiction:

Improvesystem operation simplicityVSAvoidlearning efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The system replaces complex mechanical instruction methods with electronic haptic feedback. Instead of using physical demonstrations or complex visual aids, the system uses an operation controller with haptic feedback capabilities to provide intuitive tactile guidance, maintaining simplicity while enhancing learning efficiency.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system changes the parameter of information transmission from purely visual to include tactile sensations. By introducing force tactile feedback as a new parameter, the system enriches the learning experience without significantly complicating the operation, as the feedback is automatically generated based on operation parameters.

Inventive Principle:

Principle #35Parameter changes

3Measurement precision

If pattern matching video comparison is used, then objective determination of movement differences is achieved, but tactile sensation feedback is missing

Engineering Contradiction:

Improvemovement difference detection accuracyVSAvoidforce tactile sensation

Core Design Contradiction:

Measurement precisionVSLoss of information

Solution Approach 1:

The system merges the advantages of visual pattern matching with tactile feedback. The operation controller combines the objective measurement capability of video analysis with the intuitive perception of haptic feedback, creating a comprehensive learning assistance system that provides both precise comparison and sensory guidance.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The haptic device acts as an intermediary that converts the measured movement differences into tactile sensations. While the video pattern matching provides objective measurement, the haptic device mediates this information by translating it into force feedback that the learner can physically sense, compensating for the loss of tactile information in visual-only systems.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A learning assistance system includes an operation control unit, a parameter acquisition unit, and a display control unit. The operation control unit causes an apparatus to be controlled to operate in accordance with force tactile sensation during operation by a user. The parameter acquisition unit acquires control parameters that are used for the control by the operation control unit. The operation control unit and the display control unit comparably provide, to a second user, a first control parameter acquired by the parameter acquisition unit in a case where the operation control unit controlled the operation of the apparatus based on operation by the first user and a second control parameter acquired by the parameter acquisition unit in a case where the operation control unit controlled the operation of the apparatus based on operation by the second user.
