Telescopic Contact Probe Retraction for Optical Lens Collision Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anti-collision systems for precision measurement face issues such as large ranging errors due to diffuse reflection, high manufacturing and maintenance costs, limited precision, and inability to protect small-sized or low-reflectivity samples, especially in optical devices with small working distances.
Innovation Solution
A contact type telescopic guiding and positioning anti-collision protection system comprising a guide shaft sleeve, concentrated ball slide sleeve, sliding shaft, spring, baffle, contact type sensing assembly, movable contact, and optical lens, which uses rolling friction and conical surface positioning to prevent collisions without the need for reflecting or receiving devices, allowing flexible triggering and power-off protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If laser ranging is used for anti-collision protection, then measurement capability is provided, but manufacturing cost and environmental requirements increase
Solution Approach 1:
The patent replaces optical sensing systems (laser ranging, ultrasonic ranging) with a mechanical contact-based anti-collision system. The probe includes a contact switch that triggers when the probe tip physically contacts the sample, eliminating the need for complex optical components, laser sources, and environmental control systems while providing reliable anti-collision protection.
2Ease of manufacture
If contact type sensing is used, then cost is reduced and environmental requirements are lowered, but positioning precision and triggering flexibility may be affected
Solution Approach 1:
The patent incorporates a spring mechanism that provides dynamic response to contact forces. When the probe contacts the sample, the spring compresses and triggers the contact switch, enabling the system to respond to varying contact forces and maintain positioning precision while using simple mechanical components.
Solution Approach 2:
The patent uses a contact switch as an intermediary between the mechanical probe and the control system. This switch accurately detects the moment of contact and triggers the anti-collision response, ensuring precise positioning and triggering without requiring complex sensing electronics.
3Ease of operation
If optical systems are used for ranging, then non-contact measurement is achieved, but system complexity and maintenance requirements increase
Solution Approach 1:
The patent extracts and eliminates the complex optical subsystems (laser sources, detectors, optical paths) from the anti-collision system, replacing them with a simple mechanical contact switch that requires no power supply, calibration, or environmental control, thereby dramatically reducing system complexity and maintenance needs.
