Problem

Existing particle suction machines face challenges in the connection and removal of removable receiving means, leading to inefficient sealing, external pollution, and ergonomic issues for operators, particularly during assembly and emptying processes.

Innovation Solution

The design incorporates a guide rail system with nested sleeves for the removable receiving means, allowing for a secure and ergonomic attachment and detachment process, ensuring sealed containment and minimizing exposure to particles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If adhesive tape is used to fix the bag to the hopper, then the bag can be attached, but the sealing is not guaranteed and particles may escape externally

Engineering Contradiction:
Improvesealing reliabilityVSAvoiddifficulty of correct placement
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

A rigid annular element is introduced as an intermediary component between the flexible bag and the hopper outlet. This rigid element provides a stable sealing surface that ensures reliable sealing while simplifying the attachment operation, as the rigid element can be easily positioned and fixed to the hopper outlet before attaching the bag.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The bag is designed as a flexible shell that can be securely attached to the rigid annular element. The flexibility of the bag allows it to conform to the sealing surface while the rigid annular element provides the structural stability needed for reliable sealing and easy operation.

Inventive Principle:
Principle #30Flexible shells and thin films

2Ease of operation

If adhesive tape is used to fix the bag, then attachment is possible, but removal requires tedious manipulation and particle exposure risk

Engineering Contradiction:
Improveease of removalVSAvoidparticle exposure during removal
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The rigid annular element serves as a mediator that remains fixed to the hopper outlet, allowing the bag to be easily attached and removed without tedious manipulation. The bag can be quickly detached from the rigid element, minimizing operator exposure to particles, while the rigid element stays in place to maintain sealing readiness.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If access door is located at the lower part of the machine, then structural design is simplified, but operator ergonomics deteriorate and dust exposure increases

Engineering Contradiction:
Improveaccess door positioningVSAvoidoperator ergonomics
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The rigid annular element acts as a mediator that stays fixed at the hopper outlet, allowing the bag to be attached and removed from a convenient position near the access door. This reduces the need for the operator to reach into difficult-to-access lower areas, improving ergonomics while maintaining the simplified structural design with the access door at the lower part.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The machine comprises: - a working zone (ZT) where particles are produced; - a fan (3) generating, in an internal space (9) of the machine, a flow of particles drawn in; - a hopper (4) located below said working zone and in fluidic communication with the fan's suction flow; - removable receiving means (5) located at the bottom of said hopper for receiving particles by gravity; and - a filter element (6) opening into said hopper to receive the remaining particles from the flow. Advantageously, said removable receiving means (5) comprise an inlet opening (23) with associated stiffening means (26, 27), arranged to slide in a guide rail (24) located at the outlet (18) of the bottom of the hopper.
