Solution Overview

Problem

Existing longitudinal support elements for household appliances in kitchen worktops are difficult to install quickly and efficiently, especially when dealing with varying depth and height dimensions, often requiring manual adjustment and potentially leaving gaps between appliances.

Innovation Solution

A telescopic longitudinal support element with an elastic adjustment mechanism, featuring a spring-loaded connection between two longitudinal bodies that automatically adjusts to fit different opening sizes, along with height adjustment elements and secure fastening options, ensuring easy and secure installation without manual dimensioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a telescopic support element is used to adapt to different opening sizes, then the adaptability is improved, but the device complexity increases due to the need for adjustment mechanisms

Engineering Contradiction:
Improveadaptability to different opening sizesVSAvoidcomplexity of adjustment mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The support element employs a telescopic mechanism with two longitudinal bodies (inner and outer) that can move relative to each other along the longitudinal axis. The inner longitudinal body can slide within the outer longitudinal body, allowing the support element to dynamically adjust its length to fit different opening sizes while maintaining structural integrity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The inner longitudinal body is nested within the outer longitudinal body, forming a telescopic structure. This nesting arrangement allows one support element to accommodate multiple size requirements without requiring multiple separate support elements, thereby reducing overall system complexity while improving adaptability

Inventive Principle:
Principle #7Nested doll (Nesting)

2Manufacturing precision

If manual adjustment is required to fit different depth dimensions, then the manufacturing precision is improved, but the ease of operation deteriorates due to complex installation procedures

Engineering Contradiction:
Improveprecision of depth dimension fitVSAvoidease of installation
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The spring element automatically adjusts the telescopic support element to the correct length by exerting a restoring force that pushes the inner longitudinal body against the stop element. This self-adjusting mechanism eliminates the need for manual measurement and adjustment, allowing the support element to self-fit to different opening sizes while maintaining precise depth dimension alignment

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The spring element provides continuous mechanical feedback by maintaining constant contact force between the inner longitudinal body and the stop element. This feedback mechanism ensures that the support element automatically compensates for variations in opening dimensions, maintaining precise fit without requiring manual intervention during installation

Inventive Principle:
Principle #23Feedback

3Reliability

If the support element is made secure with multiple fastening options, then the reliability is improved, but the device complexity increases due to multiple fastening mechanisms

Engineering Contradiction:
Improvesecurity of installationVSAvoidcomplexity of fastening system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The support element integrates multiple fastening capabilities into a single unified structure. The longitudinal bodies are designed with features that accommodate different fastening methods (screws, adhesive, clips) without requiring separate fastening systems, thereby improving reliability across different installation scenarios while avoiding the complexity of multiple independent fastening mechanisms

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

Solution Approach 2:

The fastening features are merged directly into the longitudinal bodies themselves rather than being separate components. The outer and inner longitudinal bodies incorporate integrated fastening elements that work together with the telescopic mechanism, combining the support and fastening functions into a single unified structure that improves reliability without adding device complexity

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If the telescopic support element is used to cover gaps between appliances, then the adaptability is improved, but the manufacturing precision becomes more difficult to maintain due to variable positioning

Engineering Contradiction:
Improveability to cover gapsVSAvoidprecision of appliance alignment
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The support element changes its longitudinal dimension parameter dynamically through the telescopic mechanism. By adjusting the length of the inner longitudinal body relative to the outer longitudinal body, the support element can adapt to different gap sizes between appliances while maintaining precise positioning, as the spring element ensures consistent contact force and alignment throughout the adjustment range

Inventive Principle:
Principle #35Parameter changes

AI summary

The support element has an internal longitudinal body joined with an external longitudinal body (12) in a longitudinal direction of a carrier element (10) so that the bodies are moved in the longitudinal direction. Longitudinal support element ends are distant from each other and converged to each other. An elastic longitudinal adjustment unit (16) i.e. spiral spring, is provided between the bodies. The adjustment unit is actuated by pressure in the longitudinal direction to exert an insertion force in a displacement direction of the ends in an insertion position of the carrier element.
