Solution Overview

Problem

Binocular displaying devices often cause visual fatigue and discomfort due to non-optimal picture positioning for individual wearers, and existing adjustment methods are cumbersome.

Innovation Solution

A method and system for automatically positioning pictures on binocular display elements based on wearer-specific parameters, such as interpupillary distance, to minimize physiological fatigue and simplify the adjustment process, using measurement means to determine and generate stereoscopic pictures with adapted margins for each eye.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a binocular displaying device is designed for an average wearer, then the device structure is simple and easy to manufacture, but it causes visual fatigue and discomfort for individual wearers with different physiological parameters

Engineering Contradiction:
Improvedevice structure simplicityVSAvoidvisual fatigue and discomfort
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by measuring the wearer's interpupillary distance and other physiological parameters, then dynamically adjusting the picture positioning parameters (horizontal position, vertical position, size) based on these measurements. This allows the device to adapt to individual wearers without changing the physical device structure, thereby maintaining manufacturing simplicity while eliminating visual fatigue caused by mismatched positioning.

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If setting means are used to adapt a binocular displaying device to a particular wearer, then the picture positioning can be optimized for the wearer, but the adjustment process becomes fastidious and complex

Engineering Contradiction:
Improvepicture positioning optimizationVSAvoidadjustment process complexity
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent implements self-service by incorporating automatic measurement means (such as cameras or sensors) that automatically measure the wearer's physiological parameters when the device is worn. The system then automatically calculates and adjusts the picture positioning without requiring the wearer to manually input data or perform adjustment operations. This eliminates the fastidious adjustment process while achieving optimal positioning tailored to each wearer.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If manual adjustment methods are used to adapt picture positioning, then some level of customization is achieved, but the process is time-consuming and cumbersome

Engineering Contradiction:
Improvepicture positioning customizationVSAvoidadjustment time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by performing the measurement and positioning calculation automatically as soon as the device is put on, before the wearer begins using it. The system pre-adjusts the picture positioning based on the measured physiological parameters, so that when the wearer starts viewing content, the optimal positioning is already in place. This eliminates the need for time-consuming manual adjustment processes during actual use.

Inventive Principle:
Principle #10Preliminary action
