Solution Overview

Problem

Existing deck board fixing devices struggle with accommodating varying board thicknesses due to expansion and inconsistent groove positions, requiring multiple types of devices and manual adjustments, which complicates installation and durability.

Innovation Solution

A universal fixing device with a base, sliding housing, and adjustable holding element that accommodates different board thicknesses and groove positions, ensuring secure attachment and drainage, featuring deformable guide members to absorb expansion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional fixed fixing devices are used, then installation is simple, but they cannot accommodate varying board thicknesses and groove positions

Engineering Contradiction:
Improveaccommodation of varying board thicknessesVSAvoidfixing device structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The housing is made movable relative to the base along guide members, allowing dynamic adjustment of the holding element's position to accommodate varying board thicknesses and groove heights. This transforms a static fixing device into a dynamic one that can adapt to different board conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The fixing device is designed with adjustable components that allow a single device type to work with multiple board models and thicknesses, eliminating the need for multiple specialized fixing devices for different board specifications.

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

2Ease of operation

If fixed fixing devices are used, then device structure is simple, but manual adjustment is required for groove position corrections

Engineering Contradiction:
Improveinstallation processVSAvoidmanual adjustment time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The housing automatically positions itself relative to the base by sliding along the guide members until the holding element engages with the groove, eliminating the need for manual measurement and adjustment by the installer.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The guide members are pre-positioned on the base to guide the housing into the correct position, preparing the adjustment mechanism in advance so that the holding element automatically aligns with the groove without requiring installer intervention.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If multiple fixing device types are used for different board models, then each device is optimized for its specific board, but device inventory and selection complexity increases

Engineering Contradiction:
Improvefixing accuracy for specific board modelVSAvoidcompatibility with different board models
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

A single fixing device design with adjustable housing and guide members can accommodate multiple board models and thicknesses, replacing the need for multiple specialized device types while maintaining reliable fixing accuracy for each board model.

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

Solution Approach 2:

The device allows changing the vertical position parameter of the holding element by moving the housing along the guide members, enabling the same device to adapt to different board thicknesses and groove positions through parameter adjustment rather than requiring different device types.

Inventive Principle:
Principle #35Parameter changes

4Adaptability or versatility

If the holding element is fixed relative to the base, then device structure is simple, but it cannot accommodate board expansion and groove height variations

Engineering Contradiction:
Improveaccommodation of expansion and groove variationsVSAvoidhousing and guide member mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The housing is designed to move dynamically along the guide members to accommodate board expansion and groove height variations, transforming a static structure into an adaptive mechanism that responds to dimensional changes in the board.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The solution adds vertical movement capability along the guide members, introducing a new dimensional degree of freedom that allows the holding element to adjust its position to accommodate groove height variations and board expansion in the vertical direction.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
