Sensor Holder With Single Snap Fitter and Harness Regulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sensor holders with two snap fitters for temperature detection sensors in image forming apparatuses are cumbersome and difficult to replace, leading to inefficiencies in maintenance and assembly.
Innovation Solution
A single snap fitter and a harness regulator are used to secure the temperature detection sensor, allowing for easier attachment and detachment, while a thermistor with temperature compensation ensures accurate temperature detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two snap fitters are used to hold the sensor, then the sensor is securely held in place, but the sensor replacement becomes cumbersome and difficult
Solution Approach 1:
The holding function is segmented into two independent mechanisms: a single snap fitter for mechanical attachment and a separate regulator for harness management. This segmentation allows the sensor to be securely held while simplifying replacement, as the regulator can be independently adjusted without affecting the snap fitter's holding function.
2Ease of operation
If a single snap fitter is used to hold the sensor, then the sensor replacement becomes easier, but the sensor may detach during operation
Solution Approach 1:
The regulator acts as an intermediary element between the harness and the snap fitter. It manages the harness to prevent interference with the snap fitter's holding action, thereby maintaining secure sensor attachment while allowing easy replacement. The intermediary regulator ensures that the harness does not compromise the single snap fitter's ability to reliably hold the sensor.
3Device complexity
If the harness is not regulated, then the structure is simpler, but the sensor may be pushed away from the snap fitter during operation
Solution Approach 1:
The regulator is designed to automatically manage the harness through its elastic properties and geometric constraints. The harness itself provides the regulation function by being constrained within the regulator's structure, eliminating the need for additional active control mechanisms. This self-service approach maintains sensor position stability while keeping the overall structure relatively simple.

AI summary
A sensor holder is provided that includes a single snap fitter, and a regulator. The single snap fitter holds a sensor. The regulator regulates a harness extending from the sensor by a regulation force such that the sensor is pushed to the snap fitter by the regulation force.
