Solution Overview

Problem

Conventional binoculars lack stability and comfort when worn on the nose, leading to limited maneuverability and reliability due to inadequate holding mechanisms, which result in discomfort and reduced usability, especially during movement.

Innovation Solution

A binocular design featuring a flexible, curved junction with inflection points that allows for adjustable nasal gap and reversible deformation of the holding element, ensuring secure fit and ease of use, combined with a case that accommodates the binocular in a stored position, maintaining tension for secure holding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If binoculars rest solely on the nose without temples, then the binoculars are lightweight and simple in structure, but they lack stability and shift easily during movement

Engineering Contradiction:
ImprovestructureVSAvoidstability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent applies this principle through the flexible retaining element made of elastomeric material that can deform and rebound to secure the binoculars on the nose without rigid temple structures. The flexible nature allows adaptation to nose contours while maintaining secure holding.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent changes the physical state of the retaining element from rigid to flexible elastomeric material, allowing it to deform under compression and rebound to maintain constant securing force. This parameter change enables stable holding without complex temple structures.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If a nose clip style retaining element is used, then the binoculars can be held securely on the nose, but the user experiences intense pinching pressure and discomfort

Engineering Contradiction:
ImproveretentionVSAvoidcomfort
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The flexible elastomeric retaining element distributes pressure evenly across the nose bridge area through its ability to conform to the nose contours, eliminating intense pinching points while maintaining secure retention.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The retaining element features curved and rounded surfaces that match the natural contours of the nose, distributing contact pressure smoothly across a broader area rather than concentrating force at sharp edges, thereby improving comfort.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Reliability

If a temple is added to one side of the frame, then the binoculars can be held more securely, but the maneuverability is limited as the user must hold the binoculars while reading

Engineering Contradiction:
Improveholding securityVSAvoidmaneuverability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent extracts the temple structure entirely from the design, relying solely on the nose-mounted flexible retaining element to provide all necessary holding security, thereby fully restoring maneuverability and hands-free operation capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The flexible retaining element automatically adjusts and secures itself on the nose through elastic deformation and rebound, providing secure holding without requiring any manual intervention or temple structures that would limit maneuverability.

Inventive Principle:
Principle #25Self-service

4Reliability

If two circular elements are used in the retaining element, then the binoculars can be attached to the nose, but the elements protrude from the outside causing discomfort and require constant adjustment

Engineering Contradiction:
ImproveattachmentVSAvoidcomfort
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent merges the retaining elements into a single integrated flexible elastomeric structure that conforms to the nose bridge, eliminating protruding circular elements and providing smooth contact surfaces for comfort during wear.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The flexible elastomeric material allows the retaining element to smoothly conform to the nose contours without rigid protruding elements, eliminating discomfort while maintaining secure attachment through elastic deformation.

Inventive Principle:
Principle #30Flexible shells and thin films

5Device complexity

If the binoculars are designed without a case, then the structure is simpler, but the retaining element suffers from long-term wear and reduced reliability

Engineering Contradiction:
ImprovestructureVSAvoiddurability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent provides beforehand protection for the retaining element through a dedicated case with a molded recess that holds the element in a relaxed state, preventing deformation and reducing wear during storage and transport.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The case enables recovery of the retaining element's original shape and position after each use, preventing cumulative deformation and wear that would occur without proper storage, thereby extending the element's service life and maintaining reliability.

Inventive Principle:
Principle #34Discarding and recovering
