Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bolt escapement devices face issues where bolts may tilt obliquely and get caught in air tube holes, and waiting bolts in rails are lifted upward, leading to wear and jamming risks.
Innovation Solution
A bolt escapement device featuring holding rails, a reciprocating blade with a bolt passageway, and a chute with bolt guides, which allows bolts to be released one-by-one without tilting and prevents waiting bolts from being lifted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a piston rod is used to push bolts laterally to release them one-by-one, then bolts can be released sequentially, but bolts may tilt obliquely and get caught in the air tube hole
Solution Approach 1:
The patent introduces a blade as an intermediary component between the piston rod and the bolts. The blade reciprocates to push bolts laterally through a bolt passageway, acting as a mediator that transfers the pushing force while maintaining bolt orientation. This intermediary mechanism prevents direct contact between the piston rod and bolt, eliminating the tilting problem while preserving sequential release capability
Solution Approach 2:
The patent replaces the direct mechanical pushing system (piston rod directly contacting bolts) with a blade-based reciprocating system. The blade moves back and forth within a guide groove, substituting the simple linear pushing mechanism with a controlled reciprocating motion that ensures bolts are pushed horizontally without tilting, thus improving positioning accuracy while maintaining productivity
2Ease of operation
If a piston rod applies lateral force to release bolts, then bolts can be pushed out, but waiting bolts are lifted upward causing wear and jamming risks
Solution Approach 1:
The blade serves as an intermediary that isolates the lateral pushing force from the waiting bolts in the rail. By using the blade to transfer force through the bolt passageway, the system prevents direct transmission of lateral force to waiting bolts, eliminating the upward lifting effect that causes wear and jamming while maintaining ease of operation
Solution Approach 2:
The patent segments the bolt release operation into distinct phases using the blade mechanism. The blade reciprocates to push individual bolts through the passageway while the closure portion isolates waiting bolts in the rail. This segmentation prevents force transmission to waiting bolts, eliminating harmful lifting effects while preserving operational simplicity
3Productivity
If bolts are flowed continuously through inclined rails, then efficient bolt supply is achieved, but bolts cannot be released one-by-one without clogging
Solution Approach 1:
The patent maintains continuous bolt flow through inclined rails for efficient supply, while the blade reciprocating mechanism ensures continuous one-by-one release. The blade constantly reciprocates to push bolts through the passageway, and the closure portion continuously isolates waiting bolts, ensuring uninterrupted sequential release that prevents clogging while maintaining supply efficiency
Solution Approach 2:
The patent uses dynamic reciprocating motion of the blade to control bolt release timing. The blade moves back and forth within a guide groove, dynamically adjusting its position to push bolts sequentially through the passageway. This dynamic mechanism provides precise timing control for one-by-one release while maintaining continuous bolt flow from the inclined rails, preventing clogging without sacrificing productivity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively releases bolts one-by-one without clogging and prevents waiting bolts from being lifted, reducing wear and jamming risks.
Implementation Method 1
The bolts hanging down in the rails are flowed continuously by natural fall
Implementation Method 2
a bolt passageway extending in the blade body in a direction acute to a moving direction of the blade body and allowing a bolt having been released to pass therethrough

AI summary
A bolt escapement device includes holding rails, a blade disposed downstream of the holding rails, and a chute disposed downstream of the blade. The blade includes: a blade body configured to reciprocate in a direction intersecting the holding rails to pass through a first position and a second position; a bolt passageway extending in the blade body in a direction acute to a moving direction of the blade body; and a closure portion provided on a side surface of the blade body. At least one of the holding rails and the chute is provided with bolt guides. When the blade body moves from the first position to the second position, a corner portion of the bolt passageway that is closer to the holding rails is inserted between a bolt having entered the bolt passageway and a subsequent bolt and the rail gap is closed by the closure portion.
