Push Button Band-Shaped Housing Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing configuration of push buttons, particularly at the corner between the front and side surfaces of an apparatus, poses a risk of accidental activation during operator movement, leading to erroneous operations.
Innovation Solution
The apparatus features a band-shaped portion extending over the side and front surfaces with a push button positioned within this range, recessed in a groove, which protrudes from the bottom, reducing the likelihood of accidental activation by providing a distinct tactile and visual cue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the push button is provided at the corner between the front surface and side surface, then the button is easily accessible to operators, but the operator may unexpectedly press the button when moving, causing erroneous operations
Solution Approach 1:
The push button is relocated from the corner (2D surface intersection) to the front surface center area, and a band-shaped portion is added extending from the front surface toward the side surface. This dimensional reconfiguration creates a distinct tactile and visual zone that separates the button from the corner region, allowing operators to access the button easily while avoiding accidental presses during movement.
Solution Approach 2:
The band-shaped portion creates a localized distinct region on the housing surface. By concentrating the push button within this band-shaped zone rather than at the corner, the design provides local differentiation that helps operators intentionally locate and press the button while minimizing accidental activation during operator movement.
2Area of stationary object
If the push button is disposed at the corner of the apparatus, then the button occupies minimal space, but the likelihood of accidental activation increases during operator movement
Solution Approach 1:
Instead of placing the button at the corner where surfaces intersect, the design extends a band-shaped portion from the front surface toward the side surface, creating a three-dimensional zone that accommodates the button. This dimensional extension provides a dedicated button area that is easily accessible while physically separating it from the corner region where accidental presses during movement are most likely to occur.
3Ease of operation
If the push button is made prominent to ensure easy location, then the button is easily found by operators, but the button becomes more susceptible to accidental presses during movement
Solution Approach 1:
The band-shaped portion creates a localized distinct region on the housing surface that serves as a visual and tactile marker for the push button's location. This local differentiation helps operators easily identify and locate the button without making it overly prominent in a way that would increase accidental presses during movement.
Solution Approach 2:
The band-shaped portion extends from the front surface toward the side surface, creating a three-dimensional zone that provides spatial context for the button's location. This dimensional extension allows operators to easily locate the button through tactile feedback and visual cues while the band's boundaries help prevent accidental activation during operator movement.

AI summary
An apparatus includes a housing in which a band-shaped portion extending over a side surface and a front surface of the apparatus is formed, and a push button disposed within a range of the band-shaped portion on the side surface, the push button protruding from the band-shaped portion in a pressing direction.
