Salt Lamp Assembly Tool-Free Light Source Replacement

Solution Overview

Problem

Existing salt lamp assemblies make it difficult to install and remove the light source from the salt crystal, often requiring tools or breaking adhesive bonds, which complicates replacement or swapping of the light source and crystal.

Innovation Solution

A salt lamp assembly design featuring a hollow crystal body with a base and retaining plate that includes an aperture and passages, allowing a light source plate with clips to be removably inserted and rotated for secure engagement, enabling easy installation and removal of the light source without tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the light source is secured within the salt crystal with fasteners or adhesive, then the light source is firmly fixed, but subsequent removal becomes difficult and requires tools or breaking adhesive bonds

Engineering Contradiction:
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The light source assembly is segmented into a light source plate and a socket portion, allowing the light source to be firmly fixed when assembled while enabling easy separation for removal. The retaining plate also segments the fixing mechanism into discrete engagement features (protrusions and recesses) that provide secure attachment yet simple release.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fixing mechanism transitions from a static adhesive bond to a dynamic mechanical engagement system. The clips can be inserted through passages and engaged with protrusions, providing firm fixation during operation, while the same mechanism allows easy disengagement by simply pulling the light source plate outward, converting the static strong bond into a dynamically controllable connection.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the light source is firmly fixed within the salt crystal, then the light source remains stable during operation, but replacement or swapping of the light source and crystal becomes difficult

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The system is divided into separable components: the light source plate, the socket, and the retaining plate. This segmentation allows the light source to be reliably fixed during operation while enabling easy replacement by simply disassembling the segmented components without tools or damage to the salt crystal.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The retaining plate acts as an intermediary component between the light source plate and the salt crystal. It provides the mechanical engagement features (protrusions and recesses) that ensure stable operation, while also serving as the interface for easy removal by allowing the light source plate to be pulled out through the aperture.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Strength

If adhesive bonds are used to secure the light source, then the light source is firmly attached, but removal requires breaking the adhesive bond which complicates the process

Engineering Contradiction:
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The adhesive bonding system is replaced with a mechanical engagement system consisting of clips, protrusions, and recesses. This mechanical system provides comparable or superior attachment strength while dramatically simplifying the removal process, eliminating the need to break adhesive bonds or use tools, and reducing the overall complexity of the attachment mechanism.

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

AI summary

A salt lamp assembly includes: a crystal body having a hollow cavity formed within the crystal body and a base attached to a bottom end of the crystal body; a retaining plate attached to the base the crystal body, the retaining plate including an aperture formed through a center of the retaining plate and at least one passage formed adjacent the aperture; and a light source plate removably inserted into the hollow crystal body through the aperture of the retaining plate, the light source plate including a socket and at least one clip extending upwardly from the light source plate for engaging the retaining plate through the at least one passage.
