Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If screws are used to fix furniture components to panels, then the connection is strong and reliable, but the assembly process becomes time-consuming and requires tools

Engineering Contradiction:
Improveconnection strengthVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The fastening device is divided into separate components: a fastening element with protruding parts that can be inserted into grooves, and a panel with corresponding insertion grooves and edge grooves. This segmentation allows for tool-less assembly while maintaining connection strength through the interlocking mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fastening device incorporates a self-locking mechanism where the flexible tongue automatically engages with the protruding part upon insertion, eliminating the need for tools or additional fastening steps. The system serves itself by automatically securing the furniture component to the panel.

Inventive Principle:
Principle #25Self-service

2Strength

If traditional screw fastening is used, then the furniture component is securely attached, but the process requires tools and skilled operation

Engineering Contradiction:
Improveattachment strengthVSAvoidassembly ease
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The flexible tongue automatically engages with the protruding part when the fastening element is inserted into the groove, creating a self-locking mechanism that secures the attachment without requiring tools or specialized skills to operate.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The flexible tongue is made of elastomeric material that can deform during insertion and then elastic rebound to lock onto the protruding part, providing both ease of operation and secure attachment through the flexibility and elasticity of the material.

Inventive Principle:
Principle #30Flexible shells and thin films

3Productivity

If a tool-less fastening mechanism is implemented, then assembly time is reduced and operation is simplified, but the locking mechanism must be sufficiently reliable

Engineering Contradiction:
Improveassembly speedVSAvoidlocking reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The flexible tongue made of elastomeric material provides reliable locking through its ability to deform during insertion and then elastic rebound to firmly engage with the protruding part, ensuring the tool-less mechanism is sufficiently secure.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The protruding part has a curved surface that complements the flexible tongue's curvature, ensuring proper engagement and distribution of forces during locking, which enhances the reliability of the tool-less fastening mechanism.

Inventive Principle:
Principle #14Spheroidality (Curvature)
