Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas combustion tools lack modularity, requiring multiple tools to meet diverse combusting and soldering needs, and are cumbersome due to fixed heating units that complicate packing and transport.
Innovation Solution
A combustion tool with a detachable heating unit design featuring an insertion pipe with wedge locking tenons, a push-button unlocking mechanism, and elastic support arms, allowing rapid assembly and disassembly of different heating units to meet various operational requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed heating unit is installed in the combustion tool, then the tool structure is simple and reliable, but the tool cannot satisfy different operational requirements (combusting, soldering, heat shrinking) and requires multiple tools
Solution Approach 1:
The heating unit is segmented from the main body of the combustion tool, allowing it to be detached and replaced. The heating unit includes a heating pipe, fasten ring, and elastic support arm with locking hook, while the main body has an insertion pipe with insertion slot. This segmentation enables different heating units to be installed on the same main body to satisfy different operational requirements.
Solution Approach 2:
The heating unit is designed to be dynamically replaceable rather than fixed. The elastic support arm with locking hook can be engaged or disengaged from the insertion slot through a push button mechanism, allowing the heating unit to be quickly swapped between different configurations (combusting, soldering, heat shrinking) based on operational needs.
2Reliability
If the heating unit is permanently fastened to the combustion tool, then the connection is stable and reliable, but the packing volume increases and portability decreases
Solution Approach 1:
The heating unit is designed as a separable component that can be detached from the main body. When not in use, the heating unit can be removed and stored separately, significantly reducing the packing volume required for transport while maintaining stable connection during operation through the locking mechanism.
Solution Approach 2:
The heating unit can be extracted from the main body when not needed for operation. The elastic support arm with locking hook allows the heating unit to be securely attached during use, but easily removed when storage or transport is required, thus reducing packing volume while maintaining connection reliability during operation.
3Adaptability or versatility
If multiple combustion tools are prepared to satisfy different requirements, then each tool can be optimized for its specific function, but the device complexity and number of components increases
Solution Approach 1:
The main body of the combustion tool is designed with universal compatibility to accept different types of heating units. The insertion pipe with insertion slot can accommodate heating units for combusting, soldering, and heat shrinking operations, allowing one main body to perform multiple functions by simply changing the heating unit attachment.
Solution Approach 2:
Multiple heating unit functions are merged into a single combustion tool system. Instead of requiring separate tools for combusting, soldering, and heat shrinking, the invention combines these functions by allowing different heating units to be installed on the same main body, reducing the total number of tools needed.
4Volume of moving object
If a detachable heating unit mechanism is implemented, then the packing volume is reduced and portability is improved, but the assembly and disassembly process becomes more complex
Solution Approach 1:
The elastic support arm with locking hook provides automatic engagement with the insertion slot when the heating unit is attached. The push button mechanism automatically actuates the locking and unlocking actions, eliminating the need for complex manual assembly procedures and reducing the complexity of the assembly process while maintaining the benefits of detachability.
5Reliability
If a locking mechanism is added to secure the heating unit, then the connection reliability is improved, but the ease of operation for assembly and disassembly decreases
Solution Approach 1:
The elastic support arm with locking hook automatically engages with the insertion slot when the heating unit is attached, providing secure connection without requiring manual locking actions. The push button mechanism simplifies the unlocking process to a single pressing action, maintaining ease of operation while ensuring reliable connection during use.
Solution Approach 2:
The push button acts as an intermediary mechanism that controls the locking and unlocking actions. By pressing the button, the user activates the elastic support arm to release the locking hook from the insertion slot, providing a simple and intuitive operation method that balances connection reliability with ease of assembly and disassembly.
