Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding devices face challenges in improving object holding ability, particularly in handling objects of varying sizes and shapes, due to difficulties in detecting fine deviations and vibrations, which can lead to object dropping or damage.
Innovation Solution
A holding device with a first holder comprising a first member and a second member, where the first sensor is disposed inside the first member to detect vibrations, allowing for precise detection of object deviations and deformations, and a controller adjusts the holding force based on these detections to prevent dropping or damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a sensor is disposed outside the holder to detect vibrations, then the detection range is wider, but external noise interferes with detection accuracy
Solution Approach 1:
The sensor is nested inside the holder body, placing the detection element within the structural component itself. This nesting arrangement allows the sensor to detect vibrations of the holder from the interior while being protected from external noise sources, directly resolving the contradiction between detection accuracy and noise interference.
Solution Approach 2:
The holder structure itself acts as an intermediary medium that transmits vibrations to the internal sensor. By positioning the sensor inside the holder, the holder becomes the transmission path for vibration signals while simultaneously shielding the sensor from external acoustic noise, thus mediating between the detection requirement and noise protection.
2Measurement precision
If multiple sensors are added to improve detection accuracy, then object deviations can be detected more precisely, but device complexity increases
Solution Approach 1:
A single sensor inside the holder performs multiple detection functions simultaneously - detecting holder vibrations, inferring object deviations, and monitoring object deformations. This multi-functionality approach achieves high detection precision without adding multiple separate sensors, thereby avoiding increased device complexity.
Solution Approach 2:
The holder structure serves dual purposes: it is both the gripping mechanism and the vibration transmission medium to the sensor. The holder's own structural response to object interactions provides the detection signal, eliminating the need for additional dedicated sensing components and reducing overall system complexity.
3Measurement precision
If a complex sensor system is used to detect fine vibrations, then detection accuracy improves, but manufacturing cost increases
Solution Approach 1:
The invention employs inexpensive, simple sensors (such as acceleration sensors or microphones) that can be easily manufactured and replaced if needed, rather than using complex, expensive precision sensing systems. The simplicity of these sensors directly reduces manufacturing costs while still achieving adequate detection accuracy for the application.
Solution Approach 2:
The invention replaces complex mechanical vibration sensing mechanisms with simpler electronic sensors that detect vibrations through electrical or acoustic means. This substitution eliminates the need for complex mechanical linkages, amplifiers, or transducers, thereby significantly reducing manufacturing complexity and cost while maintaining detection capability.
