Solution Overview

Problem

Existing spoke supply devices for spoked wheels experience issues with inconsistent beam picking and conveying, leading to downtime and increased manufacturing time due to misalignment, stacking, and the need for hub flipping during spoke insertion.

Innovation Solution

A spoke supply device with an intermediate waiting area that ensures continuous beam supply by allowing beams to be deposited one by one, featuring adjustable guides, detection means, and gravity-assisted beam isolation to ensure a constant flow to the ejection gun.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If beams are picked and conveyed directly from reserve to evacuation zone, then the structure is simple, but picking failures and misalignment cause downtime

Engineering Contradiction:
Improvebeam supply continuityVSAvoidsupply device structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

An intermediate waiting area is introduced between the picking/conveying means and the evacuation zone. This intermediary zone receives beams one by one from the picking means and supplies them to the evacuation zone, decoupling the direct connection and allowing the system to maintain operation even when picking fails or beams are misaligned.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The intermediate waiting area prepositions beams in a stable horizontal orientation before they reach the evacuation zone. By stabilizing beams horizontally in advance, the system ensures ready-to-eject beams are available even if the picking/conveying process experiences interruptions.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If beams are stabilized horizontally during guidance, then alignment improves, but supply time increases

Engineering Contradiction:
Improvebeam alignmentVSAvoidspoke supply time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The intermediate waiting area creates a horizontal equipotential zone where beams rest on a support surface. This horizontal positioning eliminates the need for complex vertical stabilization mechanisms during the supply process, maintaining alignment while reducing stabilization time compared to vertical orientation.

Inventive Principle:
Principle #12Equipotentiality

3Ease of operation

If spokes are inserted alternately from inside and outside of flanges, then both sides are loaded, but hub must be turned over which is difficult

Engineering Contradiction:
Improvehub loading operationVSAvoidmanufacturing speed
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

Instead of alternating spoke insertion from inside and outside of flanges (conventional approach), the invention positions the ejection gun and supply device to insert all spokes from one side of the hub. This inverted approach eliminates the need to turn over the hub during the process, making the operation easier and faster.

Inventive Principle:
Principle #13The other way round (Inversion)
