Swiveling Lamp Seat for Tool-Free Detector Lamp Replacement

Solution Overview

Problem

The process of changing lamps in analytical devices, particularly in HPLC detectors, is cumbersome and dangerous due to the need for disassembly and handling high-voltage lamps, posing risks to operators.

Innovation Solution

A detector with a lamp seat and movement mechanism that allows swiveling or moving between operating and service orientations, enabling automatic electric contact and mechanical positioning, facilitating tool-free and safe lamp exchange.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If the detector housing is disassembled to change the lamp, then the lamp can be replaced, but the process becomes cumbersome and time-consuming

Engineering Contradiction:

Core Design Contradiction:

Ease of repairVSLoss of time

Solution Approach 1:

The detector is divided into modular components, with the lamp housed in a separate, accessible lamp holder that can be independently accessed through the openable housing section. This segmentation allows the lamp to be replaced without disassembling the entire detector, reducing maintenance time and complexity.

Inventive Principle:

Principle #1Segmentation

2Ease of repair

If the lamp is handled during operation, then lamp replacement is possible, but high voltage poses safety risks to the operator

Engineering Contradiction:

Core Design Contradiction:

Ease of repairVSObject-affected harmful factors

Solution Approach 1:

The lamp is extracted from the main detector housing and placed in a separate, accessible lamp holder. This extraction allows the lamp to be removed and replaced without handling high-voltage internal components, isolating the replacement process from dangerous electrical elements and ensuring operator safety.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The housing is designed with an openable section that provides direct access to the lamp holder before the lamp is removed. This preliminary access mechanism allows the lamp to be safely extracted and replaced without exposing the operator to high-voltage internal components, as the dangerous elements remain enclosed in the closed housing.

Inventive Principle:

Principle #10Preliminary action

3Stability of the object's composition

If the lamp seat is fixed in the housing, then mechanical stability is maintained, but lamp exchange requires complex disassembly

Engineering Contradiction:

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The lamp holder is designed with movable characteristics, allowing it to be accessed and manipulated independently through the openable housing section. This dynamic design enables the lamp to be exchanged without fixed mechanical constraints requiring complex disassembly, while the lamp remains securely positioned during operation through the stable mounting structure.

Inventive Principle:

Principle #15Dynamics

AI summary

A detector for an analytical device for analyzing a fluidic sample includes a housing, a lamp seat arranged in the housing and configured to receive a lamp for generating an electromagnetic radiation, and a movement mechanism to swivel the lamp seat with respect to the housing, and/or move the lamp seat between an operating orientation and a service orientation, so that the movement from the service orientation to the operating orientation results automatically in an electric contact and/or a mechanical positioning, in particular alignment, of the lamp.
