Solution Overview

Problem

Existing lamps with integrated low light level bulbs, such as night lights, are difficult to maintain as they require extensive dismantling to replace burned-out bulbs, disrupting the lamp's structure.

Innovation Solution

A lamp design featuring a hollow chamber with translucent material and a locking ring mechanism allows easy access to the low light level bulbs for replacement, minimizing structural disturbance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the low light level bulb is integrated into the lamp body for decorative purposes, then the lamp provides additional night light function and decorative appearance, but the bulb becomes difficult to replace requiring extensive dismantling

Engineering Contradiction:

Improvefunctional versatilityVSAvoidbulb replaceability

Core Design Contradiction:

Adaptability or versatilityVSEase of repair

Solution Approach 1:

The lamp body is segmented into multiple components including a removable top portion, middle section, and base. The top portion can be detached to provide access to the interior chamber where the low light level bulb is located, allowing bulb replacement without dismantling the entire lamp structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The top portion of the lamp is designed to be extractible or removable from the main body. This extraction provides direct access to the interior chamber containing the bulb socket and low light level bulb, enabling easy maintenance while preserving the integrated decorative function.

Inventive Principle:

Principle #2Taking out (Extraction)

2Stability of the object's composition

If the lamp structure is made intact and enclosed for aesthetic purposes, then the lamp maintains structural integrity and decorative appearance, but access to the interior for bulb replacement becomes difficult

Engineering Contradiction:

Improvestructural integrityVSAvoidaccessibility for maintenance

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The lamp structure incorporates a dynamic element through the removable top portion. While the lamp maintains its enclosed aesthetic appearance during normal use, the top can be dynamically removed or opened to provide access for bulb replacement, then reattached to restore the intact appearance.

Inventive Principle:

Principle #15Dynamics

3Ease of repair

If extensive dismantling is required to replace the low light level bulb, then the bulb can be accessed, but the lamp structure is disrupted and replacement becomes time-consuming

Engineering Contradiction:

Improvebulb accessibilityVSAvoidreplacement time

Core Design Contradiction:

Ease of repairVSLoss of time

Solution Approach 1:

The lamp is pre-configured with a removable top portion that is designed from the outset to facilitate easy access to the bulb. This preliminary design consideration eliminates the need for extensive dismantling during bulb replacement, reducing maintenance time while preserving structural integrity.

Inventive Principle:

Principle #10Preliminary action

AI summary

A lamp having a body which defines a hollow chamber and is constructed at least in part from translucent material has one or more night lights directed upwardly and supported therein. The body includes a top crown which is held in place by a lock ring secured upon threads of a coupling device. Access to the upwardly directed night lights is obtained by removing the lock ring and moving the top crown upwardly to provide access to the hollow chamber so that one may insert his or her hand into the hollow chamber to remove and replace the lamp. The top crown is then replaced and the lock ring again secured.
