Solution Overview

Problem

Existing devices for storing or handling optical waveguides face challenges in achieving high packing density with low mechanical stress and ensuring secure, yet easily accessible, locking mechanisms due to limited space, particularly with spring pressure pins and rocker arm locking devices being insufficient or unsuitable.

Innovation Solution

A locking device with a monolithic plastic injection-molded locking element and holding element, featuring a locking bolt and actuating handle, that securely locks and automatically engages with the receptacle and housing, allowing easy manual unlocking, and requiring minimal additional installation space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If spring pressure pins are used as locking devices, then the device can be simple in structure, but insufficient locking and thus unreliable locking of the receptacle relative to the housing can be achieved

Engineering Contradiction:
Improvestructure simplicityVSAvoidlocking reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The locking element is divided into functional segments: a locking section with locking bolt, an operating section with actuating handle, and a connecting section. This segmentation allows each part to perform its specific function efficiently while maintaining overall simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The locking element is designed to be resilient and pivotable relative to the holding element, transforming from a static structure to a dynamic component that can automatically engage and disengage. This dynamic capability ensures reliable locking while maintaining simple operation.

Inventive Principle:
Principle #15Dynamics

2Reliability

If rocker arm locking devices are used, then locking reliability can be improved, but they cannot be used due to cramped spatial conditions

Engineering Contradiction:
Improvelocking reliabilityVSAvoidinstallation space
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The locking element is nested within the holding element, with the locking element pivotally connected to the holding element. This nested arrangement allows the locking mechanism to be compact while maintaining the reliability of a positive locking action, fitting within the cramped spatial conditions of the device.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Reliability

If a secure locking mechanism is implemented, then locking reliability is improved, but ease of manual unlocking deteriorates

Engineering Contradiction:
Improvelocking securityVSAvoidmanual unlocking ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The locking element is resilient and automatically engages with the holding element when the receptacle is in the correct position, providing self-locking functionality. This ensures secure locking without requiring complex manual intervention, while still allowing easy manual unlocking when needed.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The resilient nature of the locking element allows it to dynamically respond to positioning forces, automatically engaging and disengaging as needed. This dynamic behavior provides both secure automatic locking and easy manual operation.

Inventive Principle:
Principle #15Dynamics

4Reliability

If additional locking components are added to improve locking reliability, then installation space requirements increase

Engineering Contradiction:
Improvelocking reliabilityVSAvoidinstallation space
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The locking element combines multiple functions into a single integrated component: it provides locking action through the locking bolt, manual operation through the actuating handle, and resilient engagement through its flexible design. This merging eliminates the need for separate components, reducing installation space while maintaining reliability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The locking element serves multiple purposes: it acts as a locking mechanism, an operating handle, and a resilient element all in one component. This multi-functionality reduces the total number of parts needed, thereby reducing installation space requirements.

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