Elongated Detection Window Groove for Human Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing human detection systems in image forming apparatuses often have noticeable detection windows, which can affect the design aesthetics and user experience, as they are typically positioned centrally or with lengths similar to the window, making them conspicuous.
Innovation Solution
The human detection system incorporates a recessed portion with a detection window that is elongated in the right-left direction, positioned to extend to the ends of the exterior part, with dimensions where the groove length is significantly longer than the width, allowing the detection window to be less noticeable by being integrated into a groove that is part of the housing design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the detection window is disposed at a central position or with a groove length similar to the window, then the detection function is achieved, but the detection window becomes conspicuous and affects design aesthetics
Solution Approach 1:
The groove extends in the right-left direction (horizontal dimension) rather than vertically, creating an elongated shape that spans across the exterior part. This dimensional approach allows the groove to integrate the detection window horizontally, making it less conspicuous while maintaining detection functionality.
Solution Approach 2:
The groove is positioned to extend to the ends of the exterior part, creating a design element that is distributed across the housing surface. This local quality approach integrates the detection window into the overall housing design rather than treating it as a separate, conspicuous component.
2Shape
If the groove length is made significantly longer than the groove width, then the detection window becomes less noticeable, but the groove dimensions become more constrained
Solution Approach 1:
The groove dimensions are specifically configured with length greater than width, creating an elongated shape that horizontally spans the exterior part. This parameter change transforms the groove from a simple opening into a design element that conceals the detection window while providing sufficient space for the sensor.

Function Achieved in This Case
This configuration enhances the design aesthetics by making the detection window less noticeable, providing a unified and inconspicuous appearance while maintaining effective human detection functionality.
Implementation Method 1
a detection window which is disposed at a portion of the exterior part, and allows a detection wave used by the human detection sensor to pass through

AI summary
An apparatus having a human detection function includes: a housing having an exterior part; a human detection sensor that detects a human; and a detection window which is disposed at a portion of the exterior part, and allows a detection wave used by the human detection sensor to pass through. The exterior part has a recessed portion where the detection window is disposed, and the recessed portion is a groove which extends to ends of the exterior part, which are provided in a right-left direction, and the groove has dimensions such that a groove length is longer than a groove width.
