Solution Overview

Problem

Existing bed height adjustment mechanisms are costly and require additional components, increasing material and production costs, while also lacking effective height and depth limitations, particularly for child beds where safety is a concern.

Innovation Solution

The bed's frame struts are designed with thickening sections that serve as stop surfaces for height and depth limitations, allowing for simple and safe height adjustment without additional parts, using a clamping device that can be detachably connected to the frame to set the support surface height between these limits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If additional components (guide, stationary catch, limiting struts with grooves) are added for height adjustment, then height adjustment functionality is achieved, but material cost and device complexity increase

Engineering Contradiction:
Improveheight adjustment functionalityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The struts serve dual functions: they provide structural support for the bed frame and simultaneously act as height adjustment limiting elements through their thickening sections. This eliminates the need for separate guide components and stationary catches, reducing device complexity while maintaining height adjustment functionality.

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

Solution Approach 2:

The height adjustment limiting function is merged into the existing strut structure by adding thickening sections. Instead of being separate components, the limiting struts are integrated into the frame parts, reducing the number of parts and material costs while achieving the same functional effect.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If additional components (guide, stationary catch, limiting struts with grooves) are added for height adjustment, then height adjustment functionality is achieved, but material cost increases

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The height adjustment limiting function is merged into the existing strut structure by adding thickening sections. Instead of being separate components, the limiting struts are integrated into the frame parts, reducing the number of parts and material costs while achieving the same functional effect.

Inventive Principle:

This eliminates the need for separate guide components and stationary catches, reducing device complexity while maintaining height adjustment functionality.

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

3Ease of operation

If no depth limitation is provided for the front frame part, then ease of operation is improved, but safety is compromised due to risk of child falling when front frame part is fully lowered

Engineering Contradiction:
Improveease of operationVSAvoidsafety hazard
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The thickening section on the front frame part preemptively prevents the frame from being lowered beyond a safe position. The stop surface created by the thickening acts as a mechanical barrier that stops the lowering action before it can create a dangerous situation, thus preventing harm before it can occur.

Inventive Principle:
Principle #9Preliminary anti-action

4Reliability

If limiting struts with large transverse extent are added to create stop surfaces, then safety and height limitation are improved, but device complexity and material cost increase

Engineering Contradiction:
Improveheight limitation reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The height limitation function is merged into the existing strut structure by adding thickening sections. Instead of being separate components, the limiting struts are integrated into the frame parts, reducing the number of parts and material costs while achieving the same functional effect.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:
