Solution Overview

Problem

The existing access terminal box mounting systems are inconvenient to detach, often causing damage to the base and fibers due to excessive separating force, which complicates the detachment process.

Innovation Solution

The access terminal box component features a mounting plate with opposing locking slots and hooks on both the plate and the fiber optic terminal base, allowing for simple and secure detachment by operating pressing parts to release the locking mechanisms, avoiding direct contact with the base and fibers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual separation of mounting member is used for detachment, then the access terminal box can be detached from the mounting plate, but the detaching operation is inconvenient and may cause damage to the base part or fiber when separating force is too large

Engineering Contradiction:
Improvedetachment convenienceVSAvoiddamage risk to base and fiber
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The pressing part serves as an intermediary tool between the operator and the locking hook. By pressing the pressing part, the locking hook is driven to rotate and disengage from the locking slot, thereby detaching the terminal box without requiring direct manual separation of the mounting member. This intermediary mechanism reduces the risk of damage to the base part and fiber during detachment.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the direct mechanical pulling action with a rotational mechanism. The pressing part converts linear pressing force into rotational motion of the locking hook, which then disengages from the locking slot. This mechanical substitution allows for controlled detachment with reduced separating force, preventing damage to the base and fiber.

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

2Stability of the object's composition

If locking mechanism with hooks and slots is used, then secure mounting is achieved, but the detachment process becomes complex requiring specific pressing operations

Engineering Contradiction:
Improvemounting securityVSAvoiddetachment mechanism complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The pressing part is integrated with the locking hook as a single component. The pressing part is arranged on the terminal base and connected to the locking hook, combining the pressing function and locking function into one integrated structure. This merging simplifies the overall device while maintaining both secure mounting and convenient detachment capabilities.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The locking hook is designed to automatically disengage from the locking slot when the pressing part is actuated. The rotational motion of the locking hook upon pressing causes it to naturally release from the slot without requiring additional manual manipulation. This self-service mechanism reduces operational complexity while maintaining secure mounting during normal use.

Inventive Principle:
Principle #25Self-service
