Bent Rod Position Detector for Window Frame Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing position detectors for movable fittings in windows and doors are complex, requiring separate components and large spaces, with limited guidance for the rod's movement, making them difficult to install and prone to damage during transport and installation.
Innovation Solution
A compact position detector with a bent rod and integrated electronic means, including a position sensor system and battery, arranged within a casing that allows the rod to bypass the battery, enabling easier installation and protection from external damage, while the detector's housing fits within a bore on the edge of the frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a remote detection unit is used, then the detector does not require integrated batteries and circuit board, but significant space is required and the rod is minimally guided
Solution Approach 1:
The patent combines the detection unit, battery, and electronic components into a single integrated housing mounted on the frame edge, eliminating the need for separate remote detection units and wired connections. This merging reduces the overall space required while maintaining functional complexity.
Solution Approach 2:
The bent rod is nested within the housing, with its bends allowing it to fit around the battery and electronic components. The rod's path is routed through the housing interior, nesting the moving element within the stationary housing structure.
2Ease of operation
If the rod protrudes from the housing, then it can be actuated by the movable fitting, but it is vulnerable to damage during transport and installation
Solution Approach 1:
The rod is designed with bends that allow it to dynamically route around obstacles (battery, housing walls) while maintaining its actuation function. The flexible bent path allows the rod to be actuated from the exterior while protected within the housing.
Solution Approach 2:
The housing acts as an intermediary structure that protects the rod during transport while still allowing actuation. The rod passes through the housing rather than protruding externally, with the housing walls serving as the protective intermediary barrier.
3Ease of manufacture
If all components are integrated in a single housing, then installation is simplified, but space within the housing must be efficiently utilized
Solution Approach 1:
The rod is bent in multiple dimensions to route around the battery and electronic components. By changing the rod's path from a straight line to a multi-dimensional bent path, the design efficiently utilizes the three-dimensional space within the housing.
Solution Approach 2:
The rod features curved bends rather than sharp angles, allowing it to smoothly navigate around the cylindrical battery and other components. The curved geometry optimizes space utilization within the housing volume.
