Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Traditional hand controllers for lifting tables are inflexible and cannot be properly installed on surfaces of varying thicknesses due to fixed installation positions, leading to usability issues.

Innovation Solution

A hand controller design featuring an adjustable connection assembly with engagement portions and guide bevels that allow the connection portion to move up and down along the housing's thickness direction, enabling secure attachment to desks of different thicknesses through a snap connection and fastener system, along with a detachable USB module for enhanced functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the hand controller is fixedly connected to the tabletop via fixed connection parts, then the installation structure is simple, but the hand controller cannot be installed on tabletops of varying thicknesses

Engineering Contradiction:

Improveadaptability to different tabletop thicknessesVSAvoidcomplexity of connection assembly

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connection assembly is designed with movable connection parts that can adjust their position along the thickness direction of the housing. The engagement portions with teeth and grooves enable the connection parts to move up and down to adapt to different tabletop thicknesses, transforming a static fixed connection into a dynamic adjustable connection.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The connection assembly is divided into multiple independent connection parts, each with its own engagement portions. This segmentation allows each connection part to independently adjust to the tabletop thickness, providing flexibility while maintaining overall structural integrity.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If the connection assembly is made adjustable to fit different tabletop thicknesses, then adaptability improves, but the installation and positioning process becomes more complex

Engineering Contradiction:

Improveadjustability to tabletop thicknessVSAvoidease of installation

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The connection assembly utilizes elastic buckles that automatically snap into engagement with the engagement portions when the housing is installed on the tabletop. This self-service mechanism eliminates the need for complex manual adjustment or additional fastening tools, making installation simple despite the adjustable functionality.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The engagement portions with teeth and grooves act as intermediaries between the connection parts and the housing, enabling smooth positioning and secure locking without requiring precise manual alignment or complex fastening procedures.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of manufacture

If fixed connection parts are used, then the manufacturing process is simple, but the hand controller cannot be properly positioned on tabletops of different thicknesses

Engineering Contradiction:

Improvesimplicity of manufacturingVSAvoidusability of hand controller

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The connection parts are designed to move dynamically along the thickness direction to accommodate different tabletop thicknesses, ensuring that the hand controller keys are always positioned at the correct height for usability, while the manufacturing process remains relatively simple using standard injection molding techniques.

Inventive Principle:

Principle #15Dynamics

4Stability of the object's composition

If the housing and cover plate are rigidly connected, then structural stability is high, but the connection assembly cannot move to adjust to different thicknesses

Engineering Contradiction:

Improvestructural stabilityVSAvoidmovability of connection assembly

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The housing is segmented into multiple connection parts, each with independent engagement portions that can move relative to the housing body. This segmentation allows localized movement for adjustment while maintaining overall structural stability of the housing and cover plate connection.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connection parts are nested within the housing structure, with engagement portions that slide within guided slots. This nesting arrangement allows the connection parts to move for adjustment while being constrained by the housing, maintaining structural stability during operation.

Inventive Principle:

Principle #7Nested doll (Nesting)
