Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a rotatable support member is used to enable stacking and nesting positions, then the device can be stacked or nested efficiently, but the mechanism for transitioning between positions becomes complex

Engineering Contradiction:
Improvestacking and nesting capabilityVSAvoidtransition mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The resilient biasing member is configured to automatically urge the support member into either the stacking or nesting position based on the relative position of adjacent devices, eliminating the need for manual intervention or complex control mechanisms to transition between positions

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The cam mechanism translates rotational movement of the support member into linear displacement, changing the positional parameter of the support member relative to the side wall as it transitions between stacking and nesting positions, enabling automatic positioning through simple rotation

Inventive Principle:
Principle #35Parameter changes

2Stability of the object's composition

If the support member is held in position by friction or simple contact, then the structure remains simple, but the positioning stability and security are insufficient

Engineering Contradiction:
Improvepositioning stabilityVSAvoidpositioning mechanism complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The cam mechanism utilizes curved surface geometry to convert rotational motion into precise linear positioning, where the cam surface profile ensures the support member is urged into exact stacking or nesting positions with stable contact against the side wall

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The resilient biasing member acts as an intermediary element between the support member and the side, providing continuous urging force to maintain stable positioning while allowing for controlled movement during transitions between positions

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A material handling device (10) includes a base (20), a side (14), a support member (50), and a resilient biasing member (60). The side extends from the base and defines a device interior (12) with the base. The support member is disposed within the device interior proximate the side. The support member includes a cam (52) and is rotatable between a material handling device stacking position and a material handling device nesting position. The biasing member is coupled to the side and is configured to engage the cam and thereby urge the support member into one of the stacking and nesting positions. The resilient biasing member is also configured to effect a translation of the support member towards the side as the support member rotates from a position intermediate the stacking and nesting positions to the one of the stacking position and nesting positions.
