Solution Overview

Problem

Existing column shoes lack user flexibility in selecting and fastening different sizes or types of attachment units, limiting their adaptability to various concrete building elements.

Innovation Solution

The column shoe features a bolt housing with a base plate and an upper structure, incorporating a securing means that allows the attachment unit to be pressed between the upper structure and the securing means, enabling user selection and fastening of the attachment unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed attachment unit is integrated into the column shoe, then the structural integrity is maintained, but the user cannot select or choose different sizes or types of attachment units

Engineering Contradiction:

Improveuser flexibility in selecting attachment unitsVSAvoidcolumn shoe structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The column shoe is divided into separate components: the bolt housing (base structure) and the attachment unit (separate fastening component). This segmentation allows the attachment unit to be removed and replaced with different types or sizes, providing user flexibility while keeping the base structure simple and structurally sound.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bolt housing is designed with a universal interface that can accommodate multiple types of attachment units. The securing means (such as a universal clamp or fastening mechanism) can hold different attachment units, allowing the same base structure to serve multiple functions and adapt to various concrete building elements.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If the attachment unit is pre-fixed to the bolt housing, then the connection strength is ensured, but the end user cannot secure their own attachment unit

Engineering Contradiction:

Improveuser ability to secure attachment unitVSAvoidattachment unit connection

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The column shoe incorporates a securing means that enables the end user to independently secure their own attachment unit to the bolt housing. The design includes user-accessible fastening mechanisms (such as accessible bolts, clamps, or locking features) that allow non-expert users to properly install and secure attachment units without requiring specialized tools or expertise.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The bolt housing is pre-configured with the securing means and guiding features that prepare the interface for attachment unit installation. This preliminary setup ensures that when the user installs the attachment unit, the connection is made correctly and reliably from the start, maintaining connection strength while enabling user installation.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If a standardized attachment unit is used, then the manufacturing is simplified, but the column shoe cannot adapt to different concrete building elements

Engineering Contradiction:

Improveadaptability to different concrete building elementsVSAvoidcolumn shoe production

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By separating the bolt housing from the attachment unit, the manufacturing process can be optimized for each component independently. The bolt housing can be mass-produced as a standardized base structure, while attachment units can be manufactured in various sizes and types according to specific requirements, allowing the system to adapt to different concrete building elements without complicating the production of the main housing.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bolt housing is designed as a universal base that can work with multiple types of attachment units. This universality allows a single standardized housing design to be produced in large quantities, while the attachment units can be varied to suit different applications, maintaining ease of manufacture for the housing while achieving adaptability through the modular attachment system.

Inventive Principle:

Principle #6Universality (Multi-functionality)
