Color Measuring Apparatus Bottom Protrusion Buffering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Color measuring apparatuses face reduced measurement accuracy due to unstable distance between the housing bottom and the measurement unit, and gaps between the housing and the measurement target, which existing buffering structures on side surfaces cannot effectively address.
Innovation Solution
A color measuring apparatus with a protrusion member that switches between protruding and non-protruding states from the bottom surface, combined with a pressing member for impact buffering and stabilization, which mitigates impacts and suppresses gap formation between the housing and the measurement target.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a buffering member is provided on a side surface of the housing, then impact buffering is improved, but measurement accuracy deteriorates due to unstable distance between bottom surface and measurement unit
Solution Approach 1:
The buffering function is segmented from the side surface to the bottom surface. The protrusion member is specifically positioned at the bottom surface to provide buffering in the measurement direction, separating the buffering function from general housing structure and targeting it precisely where needed for measurement stability.
Solution Approach 2:
The protrusion member acts as an intermediary element between the housing bottom surface and the measurement target. It mediates the interaction by providing controlled buffering while maintaining stable positioning, thus protecting both the housing and the measurement accuracy simultaneously.
2Strength
If the housing structure is made rigid for stability, then structural strength is improved, but measurement accuracy deteriorates due to gap formation between housing and measurement target
Solution Approach 1:
The housing structure exhibits local quality differentiation: the main housing body maintains rigidity for overall structural strength, while the protrusion member at the bottom surface provides localized flexibility and buffering. This allows the structure to be rigid where needed for stability and compliant where needed for consistent contact.
Solution Approach 2:
The protrusion member introduces dynamic capability to an otherwise static rigid housing structure. It can deform elastically under load to maintain contact with the measurement target, transforming the housing from a completely rigid structure to one with controlled flexibility at the measurement interface.

AI summary
A color measuring apparatus includes an opening portion that is provided in a bottom portion of the apparatus and takes light from a measurement target into the apparatus, an incident light processing unit that processes light that enters the apparatus through the opening portion, a housing that covers an apparatus internal unit including the incident light processing unit, at least one protrusion member that is configured to switch between a first state in which the protrusion member protrudes from a bottom surface of the housing and a second state in which the protrusion member does not protrude from the bottom surface of the housing, and at least one pressing member that presses the protrusion member in a protruding direction from the bottom surface of the housing.
