Removable Window Vent Stop Bolt Channel Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior vent stops with bolts having axles through apertures in housing or cover components suffer from mechanical strain, leading to uneven wear and malfunction over time, and are complex and costly to manufacture.
Innovation Solution
A simplified removable window vent stop with a bolt having protuberances guided along channels in the housing and cover, where the bolt is urged laterally by a resilient member, reducing mechanical strain and allowing easy insertion and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a bolt contains an axle positioned through an aperture formed in the housing or cover, then the vent stop can be manufactured with simple components, but the axle protrudes from lateral sides creating mechanical strain and uneven wear
Solution Approach 1:
The invention removes the axle component entirely from the bolt assembly. Instead of having an axle positioned through an aperture in the housing or cover, the bolt is designed to move directly within channels formed in the housing and cover surfaces, eliminating the protruding axle that caused mechanical strain and uneven wear.
Solution Approach 2:
The invention introduces channels formed in the housing and cover as intermediary structures that guide the bolt's movement. These channels replace the direct axle-to-aperture interaction, providing a controlled path for the bolt that reduces mechanical strain and distributes wear more evenly across the housing and cover surfaces.
2Device complexity
If prior vent stops include axles positioned through apertures in housing or cover, then the structure is simple, but it creates mechanical strain leading to malfunction after extended use
Solution Approach 1:
The axle component is completely removed from the design. The bolt now moves directly within channels formed in the housing and cover, eliminating the source of mechanical strain that led to premature malfunction while maintaining structural simplicity through the channel-guided movement mechanism.
3Ease of manufacture
If the bolt protrudes from lateral sides of the housing, then the vent stop can be constructed with basic components, but it creates uneven wear causing malfunction
Solution Approach 1:
The protruding axle is removed and replaced with a bolt that moves within channels formed directly in the housing and cover surfaces. This eliminates the lateral protrusion that caused uneven wear while keeping the component structure simple and easy to manufacture.
Solution Approach 2:
Channels formed in the housing and cover act as intermediary structures that guide the bolt's movement laterally. This channel-guided mechanism distributes the wear more evenly across the housing and cover surfaces compared to the direct axle protrusion, improving reliability while maintaining manufacturing simplicity.

AI summary
A removeable window control device in the nature of a vent stop including a housing having a peripheral flange defining an opening, at least one channel, and a pair of opposingly oriented sockets, a bolt including at least one leg, wherein the leg further includes a protuberance and a tab, a cover including a lateral side of substantially similar shape and size of a lateral side of the housing, wherein the cover further includes a pair of opposingly oriented pegs and at least one channel, and a resilient member engaging a conduit defined in the bolt and a back side of the housing to urge the bolt along the channels formed in the housing and cover towards the opening defined by the peripheral flange of the housing. The vent stop is preferably inserted into a frame of a window.
