Thermally Insulated Test Recess for Electronic Component Temperature Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current temperature-dependent testing machinery for electronic components is complex and costly due to the need for the entire system to withstand extreme temperature variations, causing mechanical stress on robotic arms and increasing energy consumption with extensive insulation requirements.
Innovation Solution
A machinery design where the temperature-dependent test area is thermally insulated from the rest of the system, allowing only the test recess to be brought to extreme temperatures, while the robotic arms and other components remain at ambient temperature, using a thermally insulated test recess with means for generating predetermined thermal conditions via fluid circulation and a laminar gaseous flow to prevent thermal leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the whole machinery is brought to testing temperature, then temperature-dependent tests can be performed, but the machinery becomes complex and costly due to extreme temperature variations affecting all mechanical and electronic parts
Solution Approach 1:
The patent divides the testing system into two distinct zones: a temperature-controlled testing chamber and a ambient-temperature operational zone. The testing chamber is isolated thermally from the rest of the machinery, allowing only the necessary testing components to be exposed to extreme temperatures while robotic arms and control systems remain in the stable ambient environment.
Solution Approach 2:
The patent extracts the thermal testing function into a separate, isolated chamber that is thermally decoupled from the main machinery. This extraction allows the core testing capability to be maintained while removing the harmful thermal effects from the robotic arms and electronic control systems.
2Temperature
If the whole machinery is brought to testing temperature, then temperature-dependent tests can be performed, but production and maintenance costs increase
Solution Approach 1:
The patent segments the thermal loading so that only the testing chamber undergoes extreme temperature cycles, while the majority of the machinery operates in the stable ambient environment. This dramatically reduces the number of components requiring temperature-resistant materials and design, lowering both production and maintenance costs.
3Temperature
If handling robotic arms operate in extreme temperature environment, then temperature-dependent tests can be performed, but the robotic arms experience high mechanical stress and reduced lifespan
Solution Approach 1:
The patent extracts the robotic arms from the extreme temperature environment and places them in the ambient-temperature operational zone. The arms transfer components to the testing chamber through a thermally isolated interface, ensuring they never experience the extreme temperatures that would cause thermal expansion, contraction, and mechanical stress.
4Temperature
If the environment to heat or cool is wide, then temperature-dependent tests can be performed, but more powerful and expensive air conditioning systems are required
Solution Approach 1:
The patent applies thermal control locally only to the small testing chamber volume rather than the entire machinery environment. This localized approach dramatically reduces the energy required for heating or cooling, as the thermal mass to be controlled is minimal and the chamber can be efficiently isolated with insulation.
5Temperature
If the environment to heat or cool is wide, then temperature-dependent tests can be performed, but the cost of air conditioning systems increases
Solution Approach 1:
The patent confines the thermal control requirement to a small, localized testing chamber rather than a large environmental volume. This reduces the capacity requirements for air conditioning equipment, allowing the use of smaller, less expensive systems that are energy-efficient for the reduced thermal load.
