Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing solutions for attaching poles or beams to fundaments lack adjustment flexibility, are complex to mount, and often require additional costly components that weaken the fundament, making them unsuitable for varied soil conditions and incorrect positioning.

Innovation Solution

An assembly comprising a lower elliptic plate, an adjustment plate with recesses and holes, and an upper elliptic plate, allowing for adjustable attachment with few parts, enabling horizontal and vertical adjustments through movable components without relying on single, load-bearing elements, and compatible with standardized pole dimensions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If adjustment means are added to allow horizontal and vertical adjustment of the pole attachment, then adaptability to varied soil conditions and positioning flexibility is improved, but device complexity increases

Engineering Contradiction:

Improveadjustment flexibilityVSAvoidmounting complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adjustment plate is nested between the lower and upper elliptic plates, which are themselves nested on the fundament. This nested structure allows multiple adjustment functions (horizontal positioning via recesses, vertical positioning via hole alignment) to be integrated within a compact layered assembly, providing adaptability without proportionally increasing overall complexity

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The attachment assembly is segmented into distinct functional components: the lower elliptic plate for fundament attachment, the adjustment plate with recesses and holes for positioning, and the upper elliptic plate for pole attachment. This segmentation allows each component to perform its specific function independently while maintaining overall simplicity

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple components are used to provide adjustment capability, then adaptability is improved, but manufacturing cost increases

Engineering Contradiction:

Improveadjustment flexibilityVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The adjustment plate serves multiple functions simultaneously: it provides horizontal adjustment through its recesses, vertical adjustment through its holes, and acts as a structural connector between the elliptic plates. This multi-functionality reduces the need for separate adjustment mechanisms, thereby lowering manufacturing costs while maintaining adaptability

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The adjustment functions for both horizontal and vertical positioning are merged into a single adjustment plate component rather than using separate mechanisms. This consolidation reduces the total number of parts, simplifies manufacturing, and lowers costs while providing the required adaptability

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If holes are arranged in the fundament for lock bar mounting, then adjustability is improved, but fundament strength deteriorates

Engineering Contradiction:

Improvemounting adjustabilityVSAvoidfundament construction strength

Core Design Contradiction:

Adaptability or versatilityVSStrength

Solution Approach 1:

The adjustment functionality is extracted from the fundament itself and relocated to the adjustment plate. Instead of cutting holes in the fundament for adjustment purposes, the adjustment plate provides all necessary adjustment features (recesses and holes) while the fundament maintains its intact, strong structure with only the minimal centrally located through hole

Inventive Principle:

Principle #2Taking out (Extraction)

4Device complexity

If a single load-bearing bolt is used to connect the lock bar and mounting plate, then device complexity is reduced, but reliability deteriorates

Engineering Contradiction:

Improvenumber of partsVSAvoidmounting security

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

Instead of relying on a single critical load-bearing bolt, the load path is distributed across multiple local connection points: the lower elliptic plate connects to the fundament, the adjustment plate connects to both elliptic plates at multiple positions, and the upper elliptic plate connects to the pole. This distribution of load paths at different locations enhances reliability without significantly increasing complexity

Inventive Principle:

Principle #3Local quality
