Solution Overview

Problem

Existing built-in elements, such as lights, are limited to specific mounting opening diameters, restricting their versatility and increasing manufacturing and storage costs, as well as waste, due to the need for multiple variants to fit different installation sizes.

Innovation Solution

A built-in element with a mounting body that can be adjusted to fit various installation opening dimensions by changing its external dimensions through a guide body and fastening means, allowing for secure fixation and reuse across different sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a built-in element is designed with a fixed outer diameter to ensure secure mounting, then mounting reliability is improved, but adaptability to different installation opening sizes deteriorates

Engineering Contradiction:
Improvemounting reliabilityVSAvoidadaptability to different installation opening sizes
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The mounting body is designed with adjustable outer diameter through movable mounting elements (41) that can be repositioned along the guide body (3). This dynamic adjustment capability allows the element to adapt to different installation opening sizes while maintaining secure mounting through fastening means (31, 32).

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mounting body (4) is divided into separable components including the guide body (3), movable mounting elements (41), and fastening means (31, 32). This segmentation allows independent adjustment of the outer diameter while maintaining the structural integrity needed for reliable mounting.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple variants of built-in elements with different dimensions are produced to fit various installation openings, then adaptability is improved, but device complexity and manufacturing costs worsen

Engineering Contradiction:
Improvefit for various installation opening sizesVSAvoidnumber of variants
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single built-in element design serves multiple functions by accommodating different installation opening sizes through adjustment of the mounting body's outer diameter. This universal design eliminates the need for multiple size-specific variants, reducing device complexity and manufacturing overhead.

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

3Adaptability or versatility

If the outer diameter of the mounting body is made adjustable to fit different openings, then adaptability is improved, but device complexity worsens

Engineering Contradiction:
Improveadjustable outer diameterVSAvoidstructure of mounting body
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting elements (41) are nested within the guide body (3), allowing them to move along predefined paths. This nesting approach enables adjustment functionality while maintaining a compact overall structure, minimizing the increase in device complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The guide body (3) acts as an intermediary between the fixed housing and the movable mounting elements (41). It provides the structural framework and guidance necessary for adjustment while isolating the complexity of the adjustment mechanism from both the housing and the mounting elements.

Inventive Principle:
Principle #24Intermediary (Mediator)
