Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive foam is used to attach insulating panels, then bonding strength is improved, but positional accuracy deteriorates due to post-expansion
Solution Approach 1:
The patent applies preliminary action by pre-attaching fixing brackets to the insulating panel before applying adhesive foam. This preliminary fixation prevents the panel from moving during the adhesive's post-expansion phase, thereby maintaining positional accuracy while still allowing the adhesive to provide bonding strength.
Solution Approach 2:
The patent implements preliminary anti-action by using fixing brackets to counteract the harmful effect of adhesive foam expansion before it can cause misalignment. The brackets are positioned to resist the outward force of expanding adhesive, preventing positional deviation of the insulating panel.
2Manufacturing precision
If fixing brackets are used to prevent misalignment, then positional accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges the functions of the insulating panel and fixing brackets into a single pre-assembled unit. The brackets are attached directly to the panel in the factory, combining two separate components into one integrated element that is installed as a single unit on-site, thereby reducing the number of separate fixing operations required.
Solution Approach 2:
The fixing brackets are pre-attached to the insulating panels during manufacturing before delivery to the construction site. This preliminary action transfers part of the assembly work to the factory setting, reducing on-site complexity and the number of steps required during installation.
3Stability of the object's composition
If fixing brackets are used to counteract adhesive expansion, then positional stability is improved, but productivity decreases due to additional work steps
Solution Approach 1:
The fixing brackets are pre-attached to the insulating panels during manufacturing, transferring the bracket attachment operation to the factory setting. This eliminates the need for workers to install brackets on-site, thereby maintaining positional stability while improving assembly speed and productivity during construction.
Solution Approach 2:
The patent combines the insulating panel and fixing brackets into a pre-assembled unit, merging two separate installation operations into one. This integration reduces the number of discrete work steps required on-site, thereby improving productivity while ensuring positional stability through the pre-positioned brackets.
4Reliability
If numerous fixing brackets are used to prevent misalignment, then reliability is improved, but cost increases
Solution Approach 1:
The fixing brackets are pre-attached to the insulating panels during manufacturing with precise positioning, ensuring reliable alignment is built into the component itself. This preliminary action eliminates the need for additional brackets or adjustment operations on-site, maintaining alignment reliability while reducing the total number of components required.
Solution Approach 2:
The patent integrates the fixing brackets directly onto the insulating panels, merging two separate components into one unified product. This integration ensures that the necessary number of brackets is optimally positioned and secured, maintaining alignment reliability while eliminating redundant components and reducing material quantity.

Function Achieved in This Case
This method ensures minimal positional change of insulating boards during adhesive expansion, reduces the need for additional tools and fixing brackets, and saves costs by allowing quick, cost-effective assembly without built-in aids, while maintaining precise alignment.
Implementation Method 1
Adhesive foams tend to expand during curing. Depending on the adhesive foam, the expansion rates can be between 1% and 30%.
